Generic KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch - 145C Normally Closed, 5A 250V
The KSD9700/BK05-BB1D is a metallic-shell, snap-action thermal switch designed for over-temperature protection in AC circuits up to 250V/5A. It features a normally closed (NC) contact that opens at its calibrated 145°C setpoint, making it suitable for integration into appliances, power supplies, and industrial equipment.
Features
- Metallic shell construction for robust thermal conduction and durability.
- Normally Closed (NC) contact opens at a calibrated 145°C (±5°C) setpoint.
- Rated for 5A @ 250V AC, suitable for direct line-voltage switching.
- Compact form factor with 7cm lead wires for easy installation.
- Automatic reset upon cooling below the reset temperature.

The KSD9700/BK05-BB1D is a bimetallic disc-type thermal protector housed in a metallic shell for optimal heat transfer and mechanical strength. The switch operates on a snap-action principle: when the ambient temperature reaches its factory-calibrated trip point of 145°C, the bimetallic disc deforms, instantly opening the circuit to cut off power and prevent overheating.
This device is designed for automatic reset; once the temperature cools below the reset threshold (typically 10-20°C below the trip point), the contacts reclose, restoring normal operation. Its 5A/250V AC rating allows it to be wired directly into mains-powered circuits, providing a simple, reliable, and cost-effective solution for thermal protection without requiring external signal conditioning.
