Switches • Temperature Switches

Temperature switches are used to increase or decrease differential temperature in industrial and light industrial applications that utilize air and water.Industrial temperature switches often feature a high grade of enclosure and are suited for use in harsh environments. They are also resistant to the effects of shock and vibration, and feature temperatures settings of 51ºC to 337ºC.These industrial switches are available in a variety of housings including polycarbonate, stainless steel or aluminum; and feature various explosion proof ratings.
