Temperature Limit Controller SPST Switch, Auto Reset Snap-Disc Thermostats

Surface mount limit control switch (Open on Rise, SPST, Auto Reset thermostats) provide fail-safe controls for temperatures above the safety snap-disc thermostats. They operate using temperature-sensitive metals that change shape and disconnect the connected circuit when the trigger temperature is reached. They are installed on flat surfaces using two mounting holes and fasteners to hold them in place. Commonly used as protection devices to turn systems on or off when temperatures exceed or drop below their setpoint.

Snap-Disc thermostatic switch, also known as temperature limit controller SPST switch, is an bimetal automatic control element that physically deforms inside the switch according to the temperature change of the working environment, thereby generating a conduction or disconnection action. Its working principle is mainly to use the characteristics of bimetal thermal expansion and contraction of objects, sense the temperature through the temperature sensing element, and then control the on and off of the circuit.

Snap-Disc thermostatic switches are widely used in various devices that require temperature control, such as air conditioners, refrigerators, water heaters, και τα λοιπά. In air conditioners, the thermostatic switch can sense the indoor temperature and control the start and stop of the compressor according to the set temperature range, so as to keep the indoor temperature constant.

Thermostatic switches can be divided into many types according to their control methods and structural characteristics, such as vapor pressure type, Capillary tube type, gas adsorption type, bimetal expansion type and electronic thermostat. Different types of thermostatic switches have different characteristics and applicable scopes, and users can choose according to specific needs.

Εξάλλου, when using a thermostatic switch, it is necessary to pay attention to its rated working voltage, current and other parameters to ensure its normal operation and avoid safety accidents. At the same time, it is also necessary to pay attention to the installation method and environmental requirements to ensure the accuracy and reliability of the thermostatic switch.

In short, the temperature control switch is one of the indispensable and important components in modern electronic equipment. Its accuracy and reliability have an important impact on the normal operation and service life of the equipment.
