Multicomp Pro Thermal Switch, Normally Closed (NC), 120°C

The Multicomp Pro Thermal Switch is a precision-engineered thermostat device designed to reliably protect electrical components from overheating. It utilises a thermo-bimetallic snap-disc as its switching element, which triggers at a fixed, calibrated temperature to open or close the connected circuit. This action is activated by external temperature changes, with heat transferred to the switch housing via convection or direct conduction from all sides.

Featuring a normally closed (NC) contact operation, this switch is exceptionally versatile due to its robust design, wide performance range, and diverse execution options. It serves effectively as a protective switch, sensor, or controller in various applications. Its gold-plated contacts are specifically recommended for low-voltage and low-signal-current applications, ensuring reliable performance in sensitive circuits.
