KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch - 40°C NC, 10A 250V
The KSD9700/BK05-BB1D is a metallic-shell, snap-action thermal switch designed to open a circuit at a precise 40°C setpoint. This normally closed (NC) device is rated for 10A at 250V AC/DC, providing reliable over-temperature protection for motors, transformers, and power supplies.
Features
- Precise 40°C (±3°C) normally closed (NC) snap-action thermal switch.
- High-current rating of 10A at 250V AC/DC for robust circuit protection.
- Durable metallic shell construction for effective heat transfer and mechanical durability.
- Includes 7cm insulated lead wires for straightforward electrical connection.
- Compact form factor ideal for integration into appliances, power tools, and industrial equipment.

The KSD9700/BK05-BB1D is a bimetallic disc thermostat housed in a metallic shell, engineered for precise thermal management. When the ambient temperature around its sensing surface reaches the calibrated 40°C trip point, the internal bimetallic element snaps, mechanically opening the normally closed contacts to interrupt power to the protected circuit. This action provides a failsafe, non-resettable (unless manually reset after cooling) method of preventing overheating.
Its robust construction ensures reliable performance in environments with vibration or thermal cycling. The metallic shell offers excellent thermal conductivity for accurate temperature sensing and enhances the switch’s overall durability compared to plastic-housed alternatives. It is a fundamental component for safety-critical thermal cutoff applications.
