Description of the temperature switch
The temperature switch is typically used in applications where a limited temperature range is required. It can be used to monitor the temperature of machinery and equipment. Once overheating is detected, the temperature switch shuts down the machine or activates the fan to cool the unit.
Features
Bimetal is the basic component of the Wika TFS35 temperature switch. The temperature switch is equipped with a bimetal that senses temperature changes and a kick occurs when the temperature reaches the nominal switching temperature (NST).
When the temperature cools to the reset switch temperature (RST) or below, the switch returns to its original state.
The bimetal in the TFS35 temperature switch does not carry any current, so no arcing occurs.
For bimetals carrying current, there is also the danger of premature switching due to self-heating.
Reset switch temperature is typically 15 ... 40 K lower than the switch temperature.
Electrical contact design
TFS35 bimetal temperature switch has two electrical contacts design.
A normally closed (NC) electrical contact that disconnects a mechanism when it is disconnected by a circuit.
And normally open (NO) electrical contacts can close a circuit when the temperature reaches the switching temperature, thus starting the fan or warning light.
Regardless of the electrical contact design, as long as the temperature is cooled below the reset switch temperature, the electrical contact will return to its initial state, allowing the monitored device to operate normally again.
