[TR] Silicone Brake Fluid Tolerant Stoplight Switches?

[William Babbitt]

Hi Dave,
Here’s the info on the mechanical stoplight switch conversion for the TR3:


The switch came from Amazon:

Beck/Arnley Stop Light Switch -... https://www.amazon.com/dp/B000CRZEZ2?ref=ppx_pop_mob_ap_share

The threaded shaft fit perfectly in the master cylinder support frame. It only came with one nut but a quick trip to the local hardware store secured a couple more. It’s metric: 10M - 1.25 thread. 

Let me know if you need anything else.
