Combination Switch Also Known As Power Isolation Switch
- Aug 30, 2017 -

Combination switch is suitable for AC 50Hz or 60Hz, rated operating voltage to 500V circuit for cutting and switching power supply, but also directly open and close the motor and high inductance load.

The combination switch is a multi-functional modular switch used to control lighting and light signalling devices as well as some other accessories. Combination Switch It is usually a handle-type, mounted on a steering column under the steering wheel for the driver to operate.

The combination switch can control the headlamp (far-light and near-light lamp), the turning lamp, the contour lamp and the light signal. Turn on the switch and rotate to the front light position, Combination Switch the headlamp lights up, the switch up, the right turn to the light, the switch down and the left turn to light.

In the electric control circuit, a switch which is often introduced as a power supply can be used to directly start or stop a small power motor or to turn the motor upside down and backward. Local lighting circuits are also used for control. Combination switch has a unipolar, bipolar, three-pole, four-pole, Combination Switch rated continuous current has 10, 25, 60, 100A and many other.

The combination switch is mainly used as the power supply switch, also known as the Power isolating switch, is divided into the protection type and the common board after the wiring type and the ordinary plate front connection type, the switch box should use the protective type or after the board type (the switch body installs in the Switch box Electrical installation board, the front

With the combination switch, the fuse and other protection devices must be configured.

When the combination switch is installed, Combination Switch it is advisable to keep the handle in a horizontal rotation position. When selected, the rated current of the combined switch shall be equal to or greater than the sum of the load currents in the controlled circuit. When used to control the motor, its rated current is generally selected as 1.5 ~ 2.5 times times the rated current of the electric machine. The On-off ability of the combination switch is low, so it can not be used to break the fault current. When the motor is used to control the reversible operation, the electric motor must be completely stopped rotation before allowing the reverse connection. Combination Switch When the load factor is low, the capacity of the combined switch should be reduced, otherwise it will affect the service life.
