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

- Automatic reset for convenience

- Compact, but capable of high currents

- Temperature control and overheating protection

- Easy mounting and quick response

- Optional mounting bracket available

- UL and CSA recognized

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.

What does the bimetallic strip do in a thermostat?

Every metal expands when it is heated, this property of materials is called thermal expansion.

The amount of expansion is different for different materials and is determined by a property called coefficient of thermal expansion(γ).

The materials having higher coefficient of thermal expansion than others, expands more for the same rise in temperature. For example brass has high value of coefficient of thermal expansion than steel. So if there are two strips, one of brass and other of steel of same dimensions, then increasing the temperature by same amount of both the strips, the increase in length of brass strip will be more than steel strip.

Bimetallic strips :Two strips, one of steel and other of brass(some times copper) are joined together throughout their length by riveting, brazing or welding(more common). Now as the temperature is increased, the increase in length of brass strip is more than steel strip but since they are joined together lengthwise so both the strips bend in the form of an arc.

This property of different amount of expansion of different materials by increase in temperature is utilized in making temperature controlling device called thermostat to make or break electrical contact.
