Reverse light Switch - Success!

I think I've found a source for the Plus 2's reversing light switch. After I bought a couple of wrong 'uns including an Intermotor 54660 for a TR7 which was almost there but had a 3/8 UNC thread - my box has a 3/8 UNF thread for the switch.
I eventually found that Auto Electrical Spares (autoelectricalspares.co.uk) carried a Lucas SMB420 brake light switch which was 3/8 x 24 UNF fitting. So for the sake of a tenner I bought it. Now I expected it to be a 'release the plunger to turn on' mechanism but to my surprise it was a 'push the plunger in to turn on', so it works perfectly in my Ford three rail box. As no one seems to advertise these I thought I'd post this up for the hordes of you guys who have a unf bolt in the reverse light switch hole!

As the gearbox is the same in the "baby" elan
as the Plus2 I assume that the switch is the same?
Anyway here is a link to the switch to save everyone time searching -

Would this switch also be correct for the handbrake? Mine's been put somewhere so safe, even I can't find it

P.S.
I've got something like this in my pedal/box,it's a tight fit,needs the spade connectors "flattening " but does the job..

Hi Matt
Just wanted to say thank you for your post - I've been searching for the reverse switch for my 3 rail gearbox for ages to no avail (mine was physically damaged and plugs the hole but is u/s)
all the best

On the four speed the switch is screwed into a vertical hole on the top right hand side of the casing, just in front of the alloy cover on the top of the gearbox case.

I wish I'd known this a few decades ago, thank you Matt!
I fitted an oil-proof microswitch inside the gearbox, drilled a hole for the wires and sealed it with instant gasket. Many years later a short-circuit welded the switch closed, so now I have a microswitch next to the gear lever itself. FIT A FUSE, GUYS!
