How does a forward reverse switch control? The direction of a three-phase motor. Let’s start by understanding how the switch works. Although it has six external terminals, inside it contains 10 contact points. When the switch is in the center or stop position, all terminals are disconnected. Pushing the switch upward connects terminals one with two, five with six, and 9 with 10, allowing current to flow in the ABC phase sequence, making the motor rotate forward. Pushing the switch downward connects terminals one with two, three with four, and seven with eight. Changing the phase sequence to ACB, and the motor runs in reverse.

Learn how a simple manual forward-reverse switch controls the direction of a 3-phase motor. This is the easiest way to rotate your motor forward and reverse without any contactor or automation.
Perfect for electricians, engineers, and DIY enthusiasts looking to master 3-phase motor direction control with a manual reversing switch.

🔧 This trick works for most industrial motors and is essential knowledge for every technician!
