What Is A Changeover Switch?


A transfer switch is a low-voltage switch that switches multiple circuits.Multiple moving contacts are welded on the shaft. When the shaftrotates, the moving contacts are connected or broken with the staticcontacts in turn to switch the circuit. An electrical applianceswitches circuits from one set of connections to another. There are two types——separate one and integrated one.



Characteristics


◆ Convenient and Fast

◆ Safe and Reliable

◆ Economical and Environmentally Friendly

◆ Superior Efficiency



Working Conditions


◆ The ambient temperature : ≤ +40℃.

◆The average temperature within 24 hours :≤ 35℃

◆The lower limit of ambient temperature : ≥ -5℃

◆ When the highest temperature reaches +40℃, the relative air humidityshouldn’t  be more than 50%. Higher relative humidity is allowed inthe relatively lower temperature, such as 90% humidity in 20℃. The measure should be taken to deal the condensation occasionally caused by the temperature change.

◆The surrounding environment should be clean without the flammable and dangerous substances, gases that can damage insulation and metal, and conductive dust.



Operation


◆ The changeover switch drives the shaft and cam to make or break thecontact by its handle. Its cam shape is different. Thus, when the handle is in different positions, the contacts are different, so as to achieve the purpose of the conversion circuit.

◆The operation positions of the handle of the changeover switch are indicated by the angles. And different types of the switches have different contacts.



Structure

◆The changeover switch is composed of multiple groups of operatingmechanism, positioning device, contact, contact system, rotating shaft,handle and other components.

◆The changeover switch’s contact, the double break contact bridge structure, is in the insulated base. The moving contact is designed to be the automatically adjustable style to ensure that the contact can be closed and broken at the same time. Besides, the static contact is installed in the contact seat. When used, it relies on the cam and bracket to operate and control the closing and breaking of the contact.
