Generic KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch (125°C NC) - 10A 250V
The KSD9700/BK05-BB1D is a metallic-shell, snap-action thermal switch designed for reliable over-temperature protection in electrical systems. It operates as a normally closed (NC) switch, opening at its calibrated 125°C set point to interrupt a 10A load at up to 250V AC/DC, making it suitable for integration into power supplies, motor controls, and heating appliances.
Features
- Metallic shell construction for robust thermal conduction and mechanical durability.
- Normally Closed (NC) snap-action switch opens at a precise 125°C (±5°C typical) set point.
- High current handling: Rated for 10A at 250V AC or DC for direct load switching.
- Fast thermal response due to direct metal-to-metal contact and bimetallic disc actuator.
- Compact form factor with integrated 7cm lead wires for simplified installation.

The KSD9700/BK05-BB1D is a bimetallic thermal cut-off switch housed in a metallic shell, engineered for automatic over-temperature protection. Its operation relies on a calibrated bimetallic disc that snaps open at 125°C, breaking the electrical circuit to prevent damage to connected components. The metallic housing ensures rapid and accurate thermal transfer from the monitored surface to the internal actuator.
This switch is designed for direct series connection with the load, eliminating the need for external signal conditioning or control boards. Its 10A/250V rating allows it to protect motors, transformers, solenoids, and heating elements directly. The normally closed configuration ensures the circuit is complete under normal operating temperatures, providing a fail-safe open state upon overheating.
