Bimetallic thermal switches can be classified by type, such as Appearance, electrical or mechanical, or by thermostat type, such as programmable, non-programmable, or smart.
Here are some types of thermal switches:
Pressure switches
These switches have a thermal system filled with vapor that includes a sensing bulb, 毛细管, and bellows element. The bellows increases pressure when the temperature rises.

Electronical temperature switches
These switches have a thin-film resistor in a bridge circuit that provides a quick response and close switch point tolerances.

Heat-actuated switches
These switches can be mechanical, gas-gap, superconducting, or magneto-resistive. Mechanical heat switches can operate in a wide temperature range.

NTC thermistor temperature sensor
These sensors have a negative characteristic curve for increasing temperature. They are often used for temperature control.

Plugstat temperature switch
These bimetal devices have a temperature range of 0°F to 650°F (-17.8°C to 343.3°C). They are slow make and break devices that provide tight tolerance temperature sensing over a small range.

Thermostat cut off switch
These devices cut off power when the temperature rises and are often integrated into equipment to prevent overheating. A bimetal thermostat is also a type of thermal cutoff device because it opens the connection to power when it blows.
Our Fail Safe bimetal Temperature Switches are ideal when you want to call special attention to a temperature malfunction. The product has automatic and manual reset options, Because the switch needs to be manually reset, a human must interact with the switch and solve the problem before the equipment or appliance can work again.

The KSD302 Stainless Steel Miniature Disc Limit Temperature Switches provide the end-user with a wide range of functionality without impacting durability. The KSD302 disc limit thermostat is designed for use up to 510°F but can withstand temperatures up to 800°F while still protecting the set point and life of the switch. The limit filled, bimetal sensor is in direct contact with the temperature-sensing outer shell producing fast response and accurate temperature control. The external setting scale provides full range adjustment and the external lock screw allows for easy adjustment of set point.

Set Point Temperature Range: -45°F to +510°F in 25° Increments (-43°C to +266°C), 230°F / 110℃ in oil
Max System Temperature: 800°F (427℃)
Max System Pressure: 1,000 PSIG
Switch Body Ambient Temperature Range: -65°F to 225°F (-54°C to 107°C)
Wetted Materials: 316L Stainless Steel
