Generic KSD9700/BK05-BB1D 5A 250V Metallic Shell Temperature Control Switch (100C Normally Closed)
The KSD9700/BK05-BB1D is a metallic-shell, snap-action thermal cutoff switch rated for 5A at 250V AC/DC. It operates as a normally closed (NC) switch that opens at its fixed 100°C set point, providing reliable over-temperature protection for electrical appliances, power supplies, and heating elements.
Features
- Fixed 100°C (212°F) normally closed (NC) thermal cutoff switch.
- Rated for 5A continuous current at up to 250V AC/DC.
- Durable metallic shell construction for robust thermal conduction and mechanical protection.
- Snap-action bimetallic disc mechanism ensures reliable, single-use operation.
- Compact design with 7cm lead wires for easy integration into circuits and enclosures.

The KSD9700/BK05-BB1D is a bimetallic thermal cutoff switch housed in a metallic shell for effective heat transfer and durability. It functions as a safety device in circuits where overheating must be prevented. The internal bimetallic disc is calibrated to snap open at precisely 100°C, permanently breaking the circuit to halt current flow and protect downstream components.
This switch is a one-time-use, normally closed (NC) device, meaning it remains conductive under normal operating temperatures but opens irreversibly upon reaching its trip point. Its 5A/250V rating makes it suitable for a wide range of low to moderate power AC/DC applications, from small appliances to power conversion equipment, ensuring compliance with essential thermal safety standards.
