Yeah, I was thinking about one of those electric oven thermostats to let you dial in the temp.
Anybody use one of those "infinite switch" type controls like are used on the electric range burners?
This allows some power control but not a set temp, but it's a cheaper approach and ought to be quite adequate for the application.
An infinite switch
is a type of switch
that allows variable power output. They utilize a bi-metallic strip
conductive connection across terminals that disconnects with increased temperature. As current passes through the bimetal connection, it will heat and deform, breaking the connection and turning off the power. After a short time, the bimetal will cool and reconnect. Therefore, infinite switches vary the average power delivered to a device by oscillating quickly between on and off states. This makes them ideal for situations that are not sensitive to such changes, such as the resistive heating
elements in electric stoves
