I don't believe the switches themselves are sealed against leakage. I had
a fluid leak from the switch after reinstalling it following a restoration
of my '73 Midget, so I replaced it with a new switch. It leaked, too. The
problem is really the o-rings on the shuttle valve inside the assembly. If
they are not leaking, there should be no fluid getting to the switch
plunger.
The o-rings are not available separately from the assembly, but you might
be able to find some that will work at a place like Lowe's or Home Depot.
They are about 1/4 inch in diameter.
