Four-piece thermal switch pack
This pack contains four KSD301 thermal switches rated to operate at 40 Celsius degree or 104 Fahrenheit. Each unit is a normally open thermostat designed for temperature control or protection in household electric appliances.
Two-terminal heating control
The switches feature two terminals and close the circuit only when the mounting surface reaches the actuation temperature. They are suited for heating units in water dispensers, coffee makers, rice cookers, sterilisers, microwave ovens, air conditioners and similar appliances.
Rated for sustained mains voltage
Each switch handles AC 250V at 10A with a circuit resistance of 50 Mohm and insulation resistance of 100 Mohm. The contacts withstand AC 1500V for one minute, supporting reliable operation under continuous load.

Questions about this item
At what temperature does the KSD301 thermal switch close its contacts?
The switch closes when the mounting surface reaches 40 Celsius or 104 Fahrenheit.
How much power does the switch dissipate during continuous operation?
Rated for AC 250V 10A, the contacts add only 50 milliohms of circuit resistance, so self-heating is negligible.
What mounting hardware or wiring is required to install these switches?
Each unit has two terminals for soldering or crimp connectors; no extra brackets are included.
