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
