KSD-01F Bimetal Thermal Switch 2A 250V with Temperature Range 50C-150C for Circuit Board Protection
The KSD-01F temperature control switch is a fixed-temperature bimetal snap-action controller designed for circuit board applications and thermal overload protection. This compact thermal switch delivers stable performance with high precision, reliability, and long service life.
Available in TO220 packages, the KSD-01F features a snap-action single pole/single throw contact mechanism. When ambient temperature exceeds the calibrated threshold, the bimetal element rapidly moves to open or close the circuit (normally closed or normally open configuration). The switch automatically resets when temperature drops to the specified reset point, providing continuous thermal protection.
- Safe installation with high pressure resistance and reliable operation
- Compact design at under 2g weight for easy integration
- Durable construction with aluminum alloy components and high-temperature PCB circuitry
- Broad compatibility with various thermostat systems including CPU, FCC, RoHS, LCD, and TV applications
- Excellent environmental resistance for all-season operation
