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. ---------------------------------------- _________________________________________________________________ See what people are saying about Windows Live.
