Another type of thermal switch is a PTC (Positive Temperature Coefficient) thermistor; these thermistors have a "cutting off" temperature at which the resistance suddenly rises rapidly, limiting the current through the circuit. When used in conjunction with a thermistor relay, the PTC will switch off an electrical system at a desired temperature.
Resettable fuses - PolySwitch devices. A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits.
A thermistor is a semiconductor type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word thermistor is a ...

It’s a trend that’s expected to pick up pace next year, as a better economy and lower-rate environment are expected to lure companies off the sidelines.
A rotary hand control turns a shaft that is connected within the infinite switch to a cam and follower. At the off position both power line connections are interrupted. At all on positions the manual contacts connect one of the line terminals to the pilot lamp terminal and one of the terminals for the heating element being controlled.
