Sealed Bimetal Thermostat Switches

These epoxy sealed bimetal snap disc thermostat switches are highly versatile, carrying up to 15 Amps at 120VAC, are available SPST. The bimetal thermodisc within is set to a precise temperature range between -40°-220°F (-25°-105°C). The temperature range determines when the thermal switch will close, or engage the electrical circuit, and when it will automatically reset, or open. A specific temperature range may be designed according to your application needs, or choose from our standard ranges.

A variety of mounting brackets, including pipe mounts and stud mounts, are available.

Custom options such as wire leads and machine brackets are available. Please send a request for quote with your application details.
