Multicomp Pro Thermal Switch, Normally Closed, 100°C

The Multicomp Pro Thermal Switch is a highly reliable, fixed-temperature thermostat designed for precise thermal control and protection. It utilises a thermo-bimetallic snap-disc as its switching element, ensuring a sharp, definitive action when the preset temperature threshold is reached. This switch functions by opening or closing the application's circuit in response to external temperature changes, transferring heat to the switch housing via convection or direct conduction from all sides.

Its versatile design, broad performance range, and diverse execution options make it universally suitable for roles as a protective switch, sensor, or controller. It is particularly well-suited for low-voltage and signal-current applications in temperature sensing, where its gold-plated contacts ensure optimal performance. This normally closed (NC) switch is engineered for durability, capable of handling 10,000 switching cycles under its rated load.

Key Applications

This thermal switch is ideal for integration into a wide array of electrical and electronic systems where temperature monitoring is critical for safety and functionality. Its robust construction and approvals make it a trusted component in industrial and commercial settings.
