THERMOSTAT SWITCH No Normally open
STS 011
The mechanical thermostat closes when the temperature rises. Used for regulating filter fans, heat exchangers, coolers or switching signal devices in the event that the temperature limit is exceeded. The bimetal thermostat has a small hysteresis.
- Engaging adjustment dial
- Small hysteresis allows for precise regulation
- Optimised air inlets
- High switching capacity
