KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch - 145°C NC, 10A 250V
The KSD9700/BK05-BB1D is a metallic-shell, snap-action thermal switch designed for reliable over-temperature protection in AC/DC circuits up to 250V and 10A. It features a normally closed (NC) contact that opens at its calibrated 145°C set point, making it suitable for integration into appliances, power supplies, and industrial equipment.
Features
- Metallic shell construction for robust thermal conduction and mechanical durability.
- Normally Closed (NC) contact opens at a precise 145°C (±5°C) temperature set point.
- High current rating of 10A at 250V AC/DC for direct load switching.
- Compact design with integrated 7cm lead wires for simplified installation.
- Bimetallic snap-action mechanism ensures reliable, repeatable operation.

The KSD9700/BK05-BB1D is a bimetallic disc-type thermal switch housed in a metallic shell for optimal heat transfer and response. Its operation is based on a snap-action mechanism: when the ambient temperature reaches the calibrated 145°C threshold, the bimetallic disc instantly snaps to open the circuit, cutting power to the protected device. This automatic reset function occurs once the temperature cools below the reset point, typically a few degrees lower than the trip point.
Engineered for direct series connection with the load, this switch eliminates the need for external signal conditioning or amplifiers. Its metallic housing ensures accurate sensing of the environment or surface it’s mounted to, while the 7cm insulated lead wires provide convenient connection points. This device is a fundamental, cost-effective solution for overtemperature cutoff in a wide range of electrical enclosures and heating elements.
