Mark,
I think you missed the point ! He was not necessarily trying to use it
as a frequency standard. He said he was trying to RESTORE it,
including making it work !

The original thermoswitch sounds like is is a mechanical switch, so
it can't be all that accurate or stable.
I would use something like one of those TO-92 temperature sensor
chips. I would probably use a 8 pin micro with an A/D to read it
and drive a reed relay (or transistor). Analog people would use a
comparator and voltage reference chip/pot.
