Changeover switch, also known as a combination switch, is a plane operation that rotates left and right. Changeover switch is mostly used for the introduction switch of power supply in the electrical control circuit of machine tools, playing the role of isolating power supply, and can also be used as a control switch that directly controls the infrequent start and stop of small-capacity asynchronous motors. Changeover switches are also available in single, double, and triple poles.
Changeover switch is a switching appliance that can be used for two or more power supplies or load conversion. Changeover switch is composed of multi-section contacts, and is mostly used in electrical equipment to turn on and off circuits infrequently, connect power and load, measure three-phase voltage, and control the forward and reverse rotation and star-delta start of small-capacity asynchronous motors. These parts are bolted together as a whole.
GW12 is suitable for converting electrical control lines and electrical measuring instruments in circuits, and can also directly control motors.

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 humidity shouldn’t be more than 50%. Higher relative humidity is allowed in the 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.
