The Advantage of Automatic Reset Thermostat

Advantage

- The contacts have good repeatability and reliable snap action;

- The contacts are on and off without arcing, and the service life is long;

- Little interference to radio and audio-visual appliances.

- Lightweight but high durability;

- The temperature characteristic is fixed, no adjustment is needed, and -the fixed value is optional;

- High precision of action temperature and accurate temperature control;

Product Advantage

Long life, high precision, EMC test resistance, no arcing, small size and stable performance.

Feature Advantage

Automatic reset temperature control switch: as the temperature increases or decreases, the internal contacts are automatically opened and closed.

Manual reset temperature control switch: When the temperature rises, the contact will automatically open; when the temperature of the controller cools down, the contact must be reset and closed again by manually pressing the button.

Craft Advantage

One-time action:

Automatic and manual integration.

Bimetallic Thermostat

-Function
Thermostat is a device which is used to maintain a desired temperature in a system like refrigerator, air-conditioner, iron and in a number of devices.

-Principle
Thermostat works on the principle of thermal expansion of solid materials.

-Construction
A bimetallic thermostat device consists of a strip of two different metals having different coefficients of linear expansion.
The bimetallic strip works as an electric contact breaker in an electric heating circuit. The circuit is broken when the desired temperature is reached.

Due to difference in the coefficients of linear expansion of two metals, The bimetallic strip bends in the form of a downward curve and the circuit is broken. The metallic strip is in contact with a screw ‘S‘. When it becomes hot, bends downward and contact at ‘P‘ is broken. Thus, the current stops flowing through the heating coil. When the temperature falls, the strip contracts and the contact at ‘P‘ is restored.
