I've had silicon fluid in since '88 or '89 and the switch is fine. That said,
I'm probably doomed for this spring, after the glaciers in my yard melt.....
Having had quite a fight with the pedal mounted stoplight switch in my '89
Cherokee, I wondered if the design might not fit on the Tiger. Never tried it,
though.
