KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch - 5A 250V, 35°C Normally Open
The KSD9700/BK05-BB1D is a metallic-shell, snap-action thermal switch rated for 5A at 250V AC/DC, designed to open its normally closed (NC) contacts upon reaching its 35°C setpoint. This compact, durable protector integrates directly into electrical circuits for over-temperature safety in appliances, power supplies, and industrial controls.
Features
- Metallic shell construction for robust thermal conduction and durability.
- 5A switching capacity at up to 250V AC/DC for reliable circuit interruption.
- Precise 35°C (±3°C) normally open (NO) setpoint for over-temperature protection.
- Compact form factor (approx. 9 x 7 x 1 cm) for easy integration into tight spaces.
- Simple two-wire (SPST) connection for straightforward series installation in power lines.

The KSD9700/BK05-BB1D is a bimetallic disc-type thermal switch housed in a metallic shell for optimal heat transfer and mechanical strength. Its internal snap-action mechanism provides a crisp, reliable contact opening at the calibrated temperature threshold of 35°C, effectively breaking the circuit to prevent overheating in connected devices.
Engineered for direct series connection in AC or DC power lines, this switch operates as a normally open (NO) device, meaning the contacts are open at ambient temperature and close when cooled below the setpoint. Its robust design ensures stable performance across a wide range of environmental conditions, making it suitable for integration into consumer appliances, battery packs, transformers, and small motor controls where automatic thermal cutoff is required.
