Sensors and Switches are mechanical-type sensing devices that do not require power to operate. Engineered based on time-proven principles such as buoyancy, conductivity, magnetic latching, capacitance and more, SWI sensors and switches are manufactured to provide reliable industrial process measurement year after year.

SWI TS Series | Fixed Set-Point Temperature Switch


The TS Series Fixed Temperature Switch is an electromechanical device designed to detect a variation in the temperature of liquids and gases. The TS enables the user to customize a fixed temperature setpoint between +50º F (+10º C) and +250º F (+121.1º C). Comprised entirely of 316L stainless steel, additional switch options include normally-open or normally-closed contacts.

Principles of Operation

As the process temperature around the switch rises, gas filled within the stem expands. Then, a membrane within the switch body mechanically activates a snap action switch once it closes the electrical circuit.
