[Healeys] brake switch

[Tom Felts]

I have few examples of "high" pressure to activate switches, but I know of at least 2 others (BJ8's) here thatr have the same problems and they added the mechanical sw for the same reason as I.

I'm sure my pressure sw is an aftermarket one.

I guess some people have had problems with some of the switches out there,
but I have four new switches on all four of my cars, and the lights on all
of them go one with the first touch of pressure, no problems.
