Tips: What is a Forward and Reverse Switch?
The reverse switch is also called forward and reverse switch. Its function is to connect and disconnect the power supply or load, which can make the motor forward or reverse. It is mainly used as an electrical component for single-phase and three-phase motors, but it cannot be used as an automation component. It is mainly used in fields where the equipment needs to rotate in both forward and reverse directions, such as electric vehicles, cranes, elevators, elevators, etc. The reverse switch has three positions. The middle one is the separate position. Toggling one side of the motor reverses the reverse direction of the other side. In short, it controls the forward and reverse rotation of the motor.
