NO NO NO!!!!!
THOSE were the silicone proof switches I bought.
2 of them, not cheap and I called him when the first one failed within a 
month, he said he would replace it. The 2nd one leaked out of the 
plastic/bake-o-lite stuff around the metal part.
I opened up the first failed switch, the contacts were coated in a 
*silicone* like slime thus making them not make contact, sort of like 
the regular $5 pressure switches, just a metal contact no different then 
any other but the gullible people will buy into the marketing, hell, I 
did but I learned real fast.
My A40 went thru many switches and I just can not fabricate a mechanical 
switch as the pedal and master are in a straight vertical line and there 
is no room. I have tried a Jag switch with an offset lever but still no 
good.

I am thinking the old original pressure switches, if never removed from 
the car when silicone was added, retain a spot of Castrol brake fluid in 
them and this keeps the silicone away from the contacts.
I have had a couple where the original Lucas switch lasted a year or so, 
others a month at best. The ones that did not last had a 100% new brake 
system, pipes and all. And I hear of pressure switches lasting years 
with silicone, how come not mine?
