Multicomp Pro Thermal Switch, Normally Closed, 80°C

The Multicomp Pro Thermal Switch is a robust and reliable thermostatic snap-disc switch designed to protect electrical circuits by responding to temperature changes. Featuring a thermo-bimetallic snap-disc as its switching element, it offers a fixed switching temperature of 80°C with a tolerance of ±5%. Upon reaching this temperature, the switch’s double contact system opens or closes the application circuit, making it an essential component for safety and control.

Heat transfer to the switch occurs from all sides via convection or direct conduction onto its housing, ensuring accurate and responsive thermal sensing. Its universal design, wide performance range, and diverse execution options allow it to function effectively as a protective switch, sensor, or controller. For low-voltage and signal-current applications, such as sensitive temperature sensing, the switch is available with gold-plated contacts to ensure reliable performance.
