Description

The KSD9700/BK05-BB1D is a bimetallic disc thermal switch housed in a metallic shell for efficient heat transfer and mechanical strength. The switch remains open under normal operating conditions and snaps closed when the surrounding temperature reaches its calibrated set point of 95°C, completing the circuit to activate an alarm, cut-off, or safety shutdown sequence.

This device provides a simple, non-resettable over-temperature protection solution without requiring external power. Its sealed metallic housing offers good environmental resistance, making it suitable for integration into motor windings, transformers, battery packs, and heating elements where reliable thermal cutoff is critical.

Key Features

  • Bimetallic snap-action mechanism for precise and repeatable switching at 95°C.
  • Metallic shell ensures rapid thermal response and robust physical protection.
  • Rated for 5A resistive load at 250V AC/DC, suitable for direct control of small loads.
  • Normally open (NO) contact configuration ideal for alarm or shutdown circuits.
  • Pre-attached 7cm insulated lead wires simplify wiring and installation.
  • Compact and sealed design for reliable operation in varied environments.
  • High-value build for cost-effective thermal protection in volume applications.

Applications

  • Over-temperature protection in AC/DC power supplies and battery chargers.
  • Thermal cutoff for small motors, transformers, and solenoid coils.
  • Safety shutdown in heating elements for appliances like coffee makers or soldering irons.
  • Temperature monitoring and alarm triggering in industrial control cabinets.
  • Battery pack thermal management in power tools and backup systems.

Frequently Asked Questions

What is the switching action of this KSD9700 thermal switch?

This KSD9700/BK05-BB1D switch is configured as Normally Open (NO). The contacts remain open under normal temperatures and snap closed when the sensed temperature reaches the calibrated set point of 95°C. It is typically used to complete a circuit and trigger an alarm or shutdown when overheating occurs.

What is the maximum electrical load this switch can handle?

The switch is rated for a maximum current of 5 Amps at a voltage of up to 250 Volts, either AC or DC. This rating is suitable for directly switching small motors, heaters, or power relays in the protected circuit without requiring an additional intermediary relay.

How do I install and wire this metallic shell thermal switch?

Install the switch by mechanically securing its metallic shell to the component or surface you need to monitor (e.g., a motor housing or heat sink) using thermal adhesive or a clamp. Connect the two pre-attached 7cm lead wires in series with the load or alarm circuit you want to control when the 95°C temperature threshold is reached.

Is this thermal switch resettable?

No, this is a snap-action bimetallic switch. Once it closes at 95°C, it will remain closed until the temperature cools down significantly below the set point, at which point it will snap back open automatically. It does not require manual resetting.
