Temperature Switch

Temperature switches open or close a contact when temperature crosses a threshold, acting on a circuit directly with no controller or analog signal in between. Controls designers fit them when a heater or fan has to cut in and out on its own, when a failed thermostat has cooked the equipment it was protecting, or when a panel needs a hard high-limit cutout that works independently of its PLC.

 

As an authorized electrical distributor for multiple manufacturers, we stock temperature switches from Siemens, Yokogawa, Markel and more across competing lines, in a range of contact configurations and body sizes, so you can match the contact arrangement the circuit needs, compare configurations and dimensions across brands, and replace a failed switch without rewiring the panel.
