Review: Reliable Thermal KSD-301 Switch at Reasonable Prices - Ruiling brand supplies at a very low price A Reliable thermal switch in the KSD-301 configuration commonly used in a number of household devices to regulate temperatures. It operates normally in the closed position allowing current to flow to the heating elements. However, when the thermal switch reaches the temperature indicated on the switch for a specified length of time, the switch opens interrupting the flow of electricity to the heating element. When the switch cools to a preset low temperature setting it closes the circuit again allowing the electricity/current to engage the heating element once again. This switch meets my needs for maintaining a paraffin wax bath.
Review: Great temperature control sensor - These worked well for bringing my smoker back to life by correcting the low heat issue.

### ⭐⭐⭐⭐⭐ Great temperature control sensor
*by T***T on August 4, 2025*

These worked well for bringing my smoker back to life by correcting the low heat issue.

### ⭐⭐⭐⭐⭐ Replaced this part on a microwave that suddenly stopped working
*by A***Y on October 16, 2023*

Replaced this thermal control switch on a GE Microwave. This DIY needed some new tools (screwdriver with hex bits) to remove the microwave casing. The old thermal switch was melted (not sure why) and it was a bit tricky to disconnect it from the wiring. This thermal control switch (KSD301) was a close match as the previous one (KSD201) was old and too expensive to get on Amazon. The voltage, current ratings, switching temperature and the default state (closed) specified in the spec sheet inside the microwave casing were the same between the two parts. Replaced the old one with this new switch and the microwave was back working. Added advantage of this new switch is that it resets back to the original state (closed) once the temperature goes back to normal. Didn't test this feature but some other reviewers did. A 2 pack with even less cost would have been more ideal. Now I have 4 idle switches in my electronics drawer. I just hope that I will remember that when this kind of failure occurs way in the future.
