Frequently Asked Questions About Temperature Switches

Q: What is the function of a temperature switch?

Temperature switches are used to indicate or alarm when a fluid has reached a certain temperature.  In some applications temperature, switches can action an automated response when temperatures are too high or too low.

For example, switching on a fan to cool the equipment, or shutting down overheating machinery.

Q: What does normally open and normally closed mean?

When a switch is Normally Open (NO) the electrical contacts inside the switch are not touching, so the circuit is Open.  When a switch is Normally Closed (NC) the electrical contacts inside the switch are touching, so the circuit is Closed.  When used in this context, Normally refers to ambient temperature. 

Q: How do I choose a temperature switch?

To pick the right temperature switch, you need to know what temperature the switch needs to set at, the thread size and whether it should be normally open or normally closed.

Q: What does hysteresis mean with temperature switches?

The term refers to the difference between the switch point and the reset point of the switch.
