Frequently Asked Questions

What is a bimetal thermal switch?

A bimetal switch uses two bonded metals with different expansion rates. When heated, the strip bends and triggers a snap-action contact to open or close a circuit.

What's the difference between a thermal fuse and a thermostat?

A thermal fuse is a one-time use device that permanently opens at a set temperature. A thermostat is reusable and can automatically reset when the temperature drops.

Do you offer custom thermal protection solutions?

Yes, we provide OEM/ODM services including custom temperature ratings, housing designs, and branding for volume orders.

What certifications do your products have?

Our products are certified by UL, CCC, VDE, RoHS, and REACH. Full certification documentation is available upon request.
