Thread-topic: Brake Light Switch
Yes these hydraulic switches are notoriously problematic.
I am of the opinion that the contacts get pitted and so this gives the erratic 
or non closing of the circuit. Have replaced at least 10 over the years on 
other Brit cars.
The solution is to fit a relay for this issue.
However this does not help with setting sensitivity.
I have fitted a mechanicat switch on the brake pedal shaft and the operating 
point is easily set - as sensitive as you want. This switch is wired in 
parallel with the hyd. one and drives a relay. So the hyd switch is just a back 
up.
Works just fine.

Subject: [Healeys] Brake Light Switch

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
