KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch - 5A 250V, 135C NC
The KSD9700/BK05-BB1D is a metallic-shell, snap-action thermal switch designed for over-temperature protection in appliances, power supplies, and motor controls. It features a normally closed (NC) contact that opens at a calibrated 135°C, rated for 5A at 250V AC/DC, with a 7cm lead wire for easy integration.
Features
- Metallic shell bimetallic snap-action thermostat with 135°C normally closed (NC) set point.
- Rated for 5A at 250V AC/DC, suitable for direct switching of small motors, heaters, and transformers.
- Compact dimensions (approx. 20mm x 8mm x 4mm) with 7cm insulated lead wires for simplified wiring.
- Designed for reliable over-temperature cut-off in appliances, power tools, and industrial controls.
- Mechanical operation requires no external power, ensuring fail-safe protection even during power loss.

The KSD9700/BK05-BB1D is a bimetallic disc thermostat housed in a metallic shell for robust thermal conduction and mechanical durability. Its operation is based on the differential expansion of bonded metals: upon reaching the calibrated trip temperature (135°C), the disc snaps to open the normally closed contacts, interrupting the circuit to prevent overheating. After cooling below the reset temperature, the contacts automatically re-close, restoring operation.
This switch is engineered for direct series connection in the load circuit, providing a simple, cost-effective, and maintenance-free solution for thermal protection. The metallic housing ensures rapid response to ambient temperature changes, making it ideal for embedding in motor windings, transformer cores, or mounting on heat sinks within power electronics, small appliances, and battery charging systems.
