1769: In the sense of a "pin passed through the eye
of a rope, strap, or bolt to hold it in place" it’s of unknown origin but
etymologists agree it’s of nautical origin (though not necessarily from the Royal
Navy) thus the speculation that it’s a frequentative form of “tug” or “to tug” (in
the sense of “to pull”), the evolution influenced by regional (or
class-defined) pronunciations similar to tog. The wall fastener was first sold in 1934
although the toggle bolt had been in use since 1994. The term “toggle switch” was first used in
1938 although such devices had long been in use in the electrical industry and
they were widely used in motor vehicles until outlawed by safety legislation in
the 1960s. In computing, toggle was first
documented in 1979 when it referred to a keyboard combination which alternates
the function between on & off (in the sense of switching between functions
or states as opposed to on & off in the conventional sense). The verb toggle dated from 1836 in the sense
of “make secure with a toggle” and was a direct development from the noun. In computing, the toggle function (“to toggle
back and forth between different actions") was first described in 1982 when
documenting the embryonic implementations of multi-tasking (then TSRs
(terminate & stay resident programs).
Toggle is a noun, verb & adjective, toggled & toggling are verbs,
toggler, toggery and (the rare) togglability are nouns and togglable (the
alternative spelling is toggleable) is an adjective; the noun plural is
toggles. Use of the mysterious togglability
(the quality of being togglable) seems to be restricted to computer operating
systems to distinguish between that which can be switched between and that
which is a stand-alone function which must be loaded & terminated.
The Jaguar E-Type (XKE) and the toggle switches
1964 Jaguar E-Type roadster (Open Two Seater (OTS) as the factory at the time described the body-style).
Jaguar’s E-Type (sometimes informally called XK-E or XKE in the US), launched at the now defunct Geneva Motor Show in 1961, was one of the more seductive shapes ever rendered in metal. Enzo Ferrari (1898-1988) was at the show and part of E-Type folklore is he called it “the most beautiful car in the world”. Whether those words ever passed his lips isn’t certain because the sources vary slightly in detail and il Commendatore apparently never confirmed or denied the sentiment but it’s easy to believe and to this day many agree. If just looking at the thing was something visceral then driving one was more than usually tactile and over sixty years on, the appeal remains, even if some aspects in the early models (such as the seats which looked welcoming but frankly were uncomfortable and the rather agricultural (no synchromesh on first gear) Moss gearbox) were a little too tactile.
In 1968, the new wave of legislation came mostly from the US DOT so applied almost exclusively to vehicles sold in the US but such was the importance of that market it made little sense for Jaguar to continue to produce a separate line with toggle switches for sale in the rest of the word (RoW) so the decision was taken to standardize on the flatter, more rounded rocker switches. At much the same time, other changes were made to ensure the E-Type on sale in 1968 would conform also to other new rules, the most obvious being the banning of the lovely covered headlights which necessitated their replacement with higher-mounted units in a scalloped housing. In view of the extent of the changes required, it was decided to designate the updated cars as the “Series 2” (S2). Despite the perceptions of some, now fuelled by internet posts and re-posts, by 1967, Jaguar, while not a mass-production operation along the lines of a computerized Detroit assembly line, had long since ceased to be a cottage industry and as a change was made in a model’s specification, except for specified batches, that was applied to all production after a certain date. Despite the factory’s records documenting this, urban myths continue to circulate, stimulated by “unicorns” such as the handful of 3.8 litre Mark 2 sedans built after 1967 when the line was rationalized (as the 240 & 340) and restricted to the 2.4 & 3.4 litre XK-Six; those 3.8s were documented “special orders” and not ad-hoc aberrations. However, nothing in the era has resulted in as much misinformation as the specification of what came (unofficially) to be called the S1.25 & 1.5 E-Types, the most common myth being that before S2 production proper began, some cars left the factory with a sometimes unpredictable mix of S1 & S2 parts, this haphazardness accounted for by the expedient of “using up stock”. In the industry, (even in computerized Detroit) the practice was not unknown but there’s now no doubt it never applied to the 1967 E-Types. What notably attracts speculation is the phenomenon of “overlap”: a Jaguar might be found to include some “later” or “earlier” features than the build date and VIN (vehicle identification number) sugget should be fitted. It's part of the charm of the breed and is thought to be the result of the recorded “build date” reflecting when a car passed the final quality control checks so one with an earlier chassis number could be returned for rectification, thus picking up what appears to be an “out-of-sequence” date.
The pure lines of the S1 E-Type (top) were diluted, front and rear, by the need to comply with US safety legislation, the later S2's head & taillights more clunky. The collector market slang for the later headlight treatment is "sugar scoop".
The process
by which S1 evolved into S2 was transitional which is why the designations
S1.25 & 1.5 became accepted; not used by the factory, they’re said to have
been “invented” by JCNA (Jaguar Clubs of North America), the S1.25 run beginning
on 11 January 1967 after production resumed following the Christmas holiday while
the first 1.5s were built that August. Although
much is made in the collector community of the defining differences between the
“pure” S1 and the “transitional” S1.25 & S1.5, that “purity” is nuanced
because like many others, the E-Type was subject to constant product
development with changes appearing from time to time. Early in the model run, there were some
obvious changes such as (1) the modification to the “flat floors” to provide
more leg-room, (2) the integration of the bonnet (hood) louvers into the
pressing, (3) the external bonnet (really a “clamshell”) release being replaced
by an internal mechanism, (4) internal trim changes including the dashboard
materials, the console and seats, (5) the replacement of the Moss gearbox with
an all-synchromesh unit and (6) the 4.2 litre engine replacing the original
3.8. Beyond those well-known landmarks,
between 1965 and early 1967 there was also a wealth of barely detectable
(except to experts of which there are quite a few) cosmetic changes and mechanical
updates including: (1) the glass windshield washer bottle replaced with plastic
container (March 1965), (2) the addition of an alternator shield (October
1965), (3) an enclosed brake and clutch pedal box (October 1965), (4) a hazard
waring (4-way) flasher added to US market cars (November 1965), (5) sun-visors added
to roadsters (February 1966), (6) instrument lighting changed from blue to
green (March 1966), (7) the rubber boot at the base of the gear lever being replaced
by a black Ambla gaiter; there were also detail changes to the gearbox cover
and prop shift tunnel finisher (October 1966), (8) the material used for the
under-dash panels was changed from Rexine-skinned aluminum to fiberboard (October
1966) and (8) a Girling clutch master cylinder replaced the Dunlop unit (December
1966).

After the headlight covers were legislated to extinction, the replacement apparatus on the E-Types came to be called “sugar scoops”, a term earlier used for the Volkswagens & Porsches sold in North America (NA) which had to be fitted with sealed-beam headlights because of protectionist rules designed for the benefit of US manufacturers. The use of “sugar scoop” for the E-Type was appropriate because the visual link with the original utensil (which, in technical terms, is a "specialized spoon") was much more obvious than the more subtle hint seen on Volkswagens & Porsches.

The sugar scoop (centre) is Japanese, circa 1970s. Sugar scoops are used to scoop sugar from a “sugar scuttle” whereas if one’s sugar is in a “sugar bowl”, a “sugar spoon” is used. The difference between a “sugar spoon” and a “tea spoon” is the former has a deeper and usually more rounded bowl and most are supplied as part of a “tea set” or “tea service”, often with the same decorative elements.
Despite that myriad of modifications, all E-Types up to those informally dubbed 1.5 are S1s but the running changes can be of significance to restorers if the object is to emulate exactly the state in which a vehicle rolled off the production line; in events such as a concours d'elegance, judges can deduct points for even minor variations. Things became more distinct when on 11 January 1967 the first E-Type destined for the US market was built without the covered headlights and this marked the beginning of the run of what would come to be known as the 1.25 although it wouldn’t be until June-July that year the open headlights became a universal fitting on all E-Types. Unlike some cars where changes can be determined from the sequential VINs, the only way accurately to determine whether a 1967 E-Type built between January and July was fitted with covered or uncovered headlights is to authenticate the market for which it was built, those for NA using the uncovered fittings. What this meant was an analysis of successive VINs will reveal on a given day there might have been a mix of cars with the the different headlight assemblies going down the production line. Curiously, there were some 1968 E-Types built for Canada which included the triple SUs and while these included the interior changes mandated by US federal law, the Tex door mirror on the driver’s side wasn't fitted and the tail and side lights were a different specification. From 1969, Canada aligned its regulations with those of the US so from that point on, the NA specification was standardized.
Between August-October 1967, the 1.5 began to evolve and that included the twin Zenith-Stromberg carburetors replacing the triple SUs (on NA cars), the substitution of ribbed camshaft covers, a higher mounting of the headlights (to meet minimum height requirements) and the adoption of rocker switches. At this point, the teardrop tail lights remained, the most obvious external marker of the S2 being the chunky light below the rear bumper bar although, in the usual manner, updates continued, such as twin cooling fans (a good idea) and 1000-odd (the so-called "R2" run of cars, almost all of which are registered as 1971 models although some left the factory in 1970) E-Types gained a pair of "leaper" badges on the flanks, just behind the front wheel arches. Unlike the centrally mounted steel leapers used on the saloons, the badge used on the flanks required two part numbers, one each for the left & right. It seemed a pointless addition and just more clutter, as they were on the S1 (1968-1973) & S2 (1973-1979) XJs.

So much did the clutter created by bigger bumpers, protuberant headlight assemblies, badges and side-marker lights detract from the lovely, sleek lines of the Series 1 cars, bolting a luggage rack to the boot (trunk) probably seemed no longer the disfigurement it would once have been. The left-hand (left) and right-hand (right) badges, being directional, were different part numbers (BD35865 & BD35866 respectively) and those used on E-Types were silver on black. There were also variants used on the XJs which were gold on black and some had the leaping feline at a slight slope, both matters of note for those wishing to restore to the challenging "factory original" standard.
So it can be hard to follow without a flow chart but, because of some overlaps in the production process, the S1-to-S1.25-to-S1.5 transition wasn’t entirely lineal but none of this is mysterious because Jaguar’s Factory Service Bulletins (JFSB) have documented these “inconsistencies” (which were standard industrial practice). For example, there were a certain 32 specific NA market vehicles fitted with the headlight covers which were built with serial numbers later than the first of the open headlight cars. Not all E-Types built for NA in 1967 thus had the open headlights and a not insignificant number of those 1.25 spec vehicles have been retro-fitted with the covers. Such is the appeal of the covered headlights that although the E-Type market is monitored by the originality police (the “matching numbers” crowd which have an extraordinary knowledge of things like “correct” hose clamps or screw heads), there seems to be much untypical forgiveness for “back-dating” headlights to the sleeker look and they're not unknown even on the later, and much different, S3 cars.
The lure of the headlight covers: 1973 E-Type with headlight covers subsequently added (left) and with the original "sugar scoops" (left). These are US market cars with the additional "dagmars" appended to the bumperettes. Even by 1973, thin whitewall tyres were still a popular option on US Jaguars and they remained available until the last were sold in 1975 but the wide whitewalls often supplied in the early 1960s had long fallen from favor. Although the judges in the JCNA confederation are usually uncompromising members of the originality police, they make a rare exception in not deducting points from late-build E-Types (the so-called 1.25 & 1.5) which have been fitted with the headlight covers. Although the covers never appeared on the S3 E-Types, their presence clearly doesn't dissuade buyers because the S3 pictured above (left), in February, 2021 sold at auction for US$230,000. It was an exceptionally low-mileage example (8000-odd miles (13,000 km)) but even given that it represented an impressive premium.
While the loss of the toggle switches, teardrop taillights and headlight covers was a cause of some lament, some other changes also induce pangs of regret. The switch from three to two carburetors was necessitated by the emission control regulations; the claimed horsepower dropped from 265 to 246 and while not many took the original rating too seriously, there was a drop in performance, especially in the upper speed ranges. One often less noticed change mandated by the DOT was the replacement of the “eared” knock-off hubs for the wire wheels (the E-Types only ever using a two-eared version although third-party items with three ears are available) with a more “pedestrian friendly” type which, bewilderingly, are now referred to as the “non-eared”, “curly”, “octagonal”, “smooth”, “federal” “safety” and “continental” knock offs. Take your pick. Buyers could also take their pick of whether their “improved” wire wheels (now incorporating a forged centre hub) were painted in matte silver or chromed although the JFSB did caution that because of the altered configuration of the spokes, the wheels were not interchangeable with the earlier type except as a complete set (ie five per car). Available from 1 January 1968 (the effective date for many of DOT’s new rules), this was Jaguar’s last update of the wire wheels which, in a variety of forms, the company had been using since being founded in 1922 as the Swallow Sidecar Company. Never offered on the biggest and heaviest of the post-war cars (the Mark VII, VIII, IX and X/420G) or the new XJ range, they were last used on the “overlap” Daimler saloons (250 & Sovereign) in 1969 although they remained an option for the E-Type until the last was built in 1974. Although a handful of small-scale producers continued to offer wire wheels, their final appearance on the option lists of the UK industry’s volume models came in 1980 when the last MGB was built.
Norway’s Motorhistorisk Klubb Drammen (Historic Car Club of Drammen) from Buskerud county reported on an exhibition hosted on 2 July 2014 by the Norsk motorhistorisk museu (Norwegian Motor Historic Museum) in the village of Brund, the event honoring Lindsay Lohan’s (b 1986) 28th birthday. The S2 Jaguar E-Type was recently restored but it would require a detailed examination to determine the degree to which (note the triple carburetors) it remains in its original specification. Given the location this may have been a RoW car but there’s a lively two-way trans-Atlantic trade in E-Types (many now restored in Poland) so it may originally have been sold in the US or Canada.
The “Shaguar” used in the three Austin Powers movies (1997, 1999 & 2002).
The Shaguar was a 1967 S1.5 E-Type which thus featured the combination of teardrop taillights, sugar scoop headlights and rocker switches and, being right-hand drive (RHD), it wasn't built for NA. When the auction house published the photographs, the vibrant on-line Jaguar community did their analysis and concluded it was built in December 1967 as a 1968 model but was in far from original condition (beyond the obvious paint and Shaguar badge). The dashboard included the earlier manual choke and the heater and vent controls appeared to be missing and while the side & turn lights were NA specification, the taillights were those used on RoW cars. The tachometer was the one one fitted to S2 models and it was suspected this may have been swapped when the later, non-original engine with the twin Zenith-Stromberg carburetors was installed. Over the decades, many E-Types have for one reason and another drifted far from their original build and usually this limits their appeal to collectors but at Mecum Auctions in January 2025, the Shaguar achieved US$880,000 (including 10% buyers premium), several times the typical sale price of a non-original S1.5 E-Type in the same condition, its history as a cinema prop clearly an attraction.
