The mechanical thermostat NO (normally open) closes when the temperature rises and is used to control filter fans, heat exchangers, cooling devices or to switch signal transmitters when the temperature is exceeded. The bimetal thermostat has a small hysteresis.

| Note | The controller's contact system is exposed to the effects of the environment, which can change the contact resistance. This can lead to a voltage drop and/or self-heating of the contacts. Switching resistive loads (switching inductive loads). Wire end ferrules must be used for connections with stranded wires. |
