Multicomp Pro Thermal Switch, Normally Closed, 70°C

The Multicomp Pro Thermal Switch is a precision snap-action thermostat designed for reliable temperature regulation in a wide array of systems. This normally closed (NC) switch activates upon sensing a temperature of 70°C, automatically cutting power to heating elements or activating cooling systems to maintain a safe and consistent environment. Its robust construction and manual reset function make it a dependable safety component in critical applications.

Engineered for durability, the switch features high-grade materials including AgNi/Cu contacts, a brass stationary arm, and a PF case with an aluminium cap. The internal bimetal disc and alloy copper movable arm provide consistent snap-action performance, while the steel reset pin ensures reliable manual operation. With a heat resistance of up to 170°C, it is built to withstand demanding operational conditions.
