KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch - 150°C NC, 10A 250V
The KSD9700/BK05-BB1D is a metallic shell, snap-action thermal switch designed for reliable over-temperature protection in electrical circuits. It operates as a normally closed (NC) switch, opening at its 150°C set point to interrupt power, and is rated for 10A at 250V AC/DC loads.
Features
- Normally Closed (NC) snap-action thermal switch with a fixed 150°C (±5°C) trip point.
- Rated for 10A resistive load at 250V AC/DC, suitable for direct control of heaters, motors, and transformers.
- Durable metallic shell construction ensures robust mechanical protection and efficient thermal conductivity.
- Compact design with 7cm lead wires for easy integration into appliances, power supplies, and industrial equipment.
- Provides fail-safe, automatic reset upon cooling below the set point for continuous protection cycles.

The KSD9700/BK05-BB1D is a bimetallic disc thermal protector housed in a metallic shell. It functions as a single-pole, single-throw (SPST) normally closed switch. When the ambient temperature surrounding its shell reaches the calibrated 150°C set point, the internal bimetallic disc snaps open, breaking the electrical circuit to prevent overheating damage to connected components.
This switch is designed for direct series connection with the load, offering a simple, non-electronic solution for thermal protection. Its metallic housing provides excellent durability and heat transfer, ensuring accurate response to ambient temperature changes. The device automatically resets once the temperature drops sufficiently below the trip point, allowing for unattended, cyclical operation in applications like coffee makers, transformers, battery packs, and small industrial heaters.
