Automatic Reset Thermostat Switch →
This type of control can be built to either open or close its electrical contacts as the temperature increases. Once the temperature of the bimetal disc has returned to the specified reset temperature, the contacts will automatically return to their original state.
Epoxy Sealed Thermostat Switch →
The epoxy sealed thermostat switch is designed for extended use in extreme environments. These automatic reset switches are built using our patented metal sleeve rivet construction and sealed to protect against salt spray, water, moisture and heat.
Manual Reset Thermostat Switch →
This type of control is available only with electrical contacts that open as the temperature increases. The contacts may be reset by manually pushing on the reset button after the control has cooled below the open temperature calibration.
Single Shot Operation Thermostat Switch →
The single shot thermostats are specifically designed as high limit devices for applications where automatic reset thermostats are not desired. These reliable devices are especially well-suited for application in small and major appliances and industrial and high technology products. To insure that a safe combination of thermostat and application is achieved, the purchaser must determine product suitability for their individual requirements

1/2″ vs. 3/4″ Bi-metal Disc
I am making a home made solar panel. Can you recommend an on-off switch.
Because of the vast array of things you could do or control with your solar panel I would need a little more information on the system being controlled in order to recommend a switch.
Thank you
My company is searching for a True DC Thermostat that can be a snap type disc or other but it has to be able to handle switching 1200 watts, 37 volts up to 35 amps DC Arcing is a major problem when trying to use AC design thermostats and can be dangerous when using to heat hot water.
Unfortunately our switches are only rated for 0.5 amps at 24 VDC, so we don’t have anything that would meet that requirement.
