S4 headlight switch bezel cup

Does anyone know the origin of the chrome outer and inner cups used to hold the S4 headlight switch in place?

These two cups. The chrome on fits inside the other to 'sandwich' the dash and held together with the standard British switch holder, the one with the two notches in it.

Hmmmm thinking maybe cortina wiper / washer switch, where the recess allows for the washer pump to be pressed in? Would need to see both side by side however

I just looked at my S1-S2-Coupe parts book, which is a great place to look for sources of Elan parts. The cups were not even pictured. This vacuum switch was used on all Elan models. Interesting that the switch itself is a Lotus derived number, but the knob has a 109E Ford number, leading me to surmise that the cups and slotted nut were part of the switch. I do know that the nut is similar but larger diameter as those used on Lucas push-pull switches. I had misplaced the nut on my SS while it was recently out of the car, and I checked every Lucas switch I had for a replacement nut. I gave up on the replacement when I found the original.

I made a pair of cups to locate a Lucas push-pull switch in the dash of Lotus 20/22 Formula Junior. They are aluminum, made on my lathe.

Appreciate it guys. I checked my Cortina sources but unfortunately these are unheard of. My S4 parts book doesn't show these either but having a Federal Sprint, I"ve come across Europa stuff in my car quite often. Perhaps if anyone has a Europa parts manual, I'd appreciate it if you can tell me if these parts are listed.

I found the cups. They are the same as used on early Elan windhield wiper switch with the manual washer pump. I could not find the correct chrome nut but I have a knurled one that fits and you can cut a groove in it. Groovy baby! I'll mail it out tomorrow.

Thanks Bob! I owe you a lunch at the Paradise Pup.

p.s. - still wondering if they're unique to Lotus.

I have Sunbeams and they look very much like the ones used for the dash mounted manual windscreen washer pumps. I will measure one tonight and post the results. Eric

The Sunbeam one measures 3/4 inches across and 3/4 inches deep. The cup that fits on the back of the dash is a bit wider. Eric

It may be a case of looking for suitable egg-cups and bottle-tops that can be converted.
