[TR] Silicone Brake Fluid Tolerant Stoplight Switches?

[aribert neumann]

I have a '61 Ford Falcon.   Also has the hydraulic stop light switch.
 Original switch lasted approx 40 yrs.   Once I switched over to DOT5, the
switch lasted a few more months.   My car gets about 7 to 9 months to a
switch when using DOT5.   I have used several different brands of switches,
all with the same results.    I typically tap my brakes to check the brake
light function (usually I check all lights) on every vehicle prior to
opening the garage door.  My experience is that the pedal force to activate
the switch increases as the switch begins to fail.  Then I know that I need
to change the switch in the next few weeks.   I now buy my switches (half
dozen at a time) from Rockauto buying Standard Motor brand.   This brand
also now has the disclaimer not to use w/ DOT5.    For me the DOT5 is
with the trouble with the switches.

im not sure we are fine.
i am constantly replacing the switch on my TR3 and my friends TR3. both of
us using dot 5.
it seems we get 9 to 12 months use per switch.
been happening for the better part of the last 10 years.
we don't get sludge accumulation, the switch just stops working.
have tried the moss, TRF and napa parts.

would love to find a compatible switch.

Ignore the warning.  They have to put that in there because if you mix Dot
5 and 3/4 you get sludge.   In this litigious society they put that in to
avoid being sued.  You are fine.
