[Healeys] Brake Light Switch

[Bob Spidell]

A while ago, I bought a 'sensitive' brake light switch from Ron Francis 
Racing (IIRC, based on a recommendation from someone here).  Today I 
tried to install it and it has the wrong threads, which I only realized 
after fabbing a couple leads for it.  So my question is, does anybody 
make a higher-quality--i.e. more sensitive--switch that will actually 
fit a Healey's brake lines? I've got a mechanical switch, but would 
prefer to stay with the hydraulic if I can find one that doesn't take a 
quarter-pedal of motion to activate.

Also, the threads on my (now broken) current switch appear to be 
machine, whereas the RFR switch was 1/8" pipe; anyone know what the 
correct size of the current switch is (I had to put it back in to stop 
the leak).

TIA,

Bob
