Key Features:
1. Purpose: To change the direction of a 3-phase motor’s rotation, such as in hoists, conveyors, or other motor-driven machinery.
2. Operation: It allows manual or automatic switching between two wiring configurations:
Forward: Standard L1, L2, L3 connection.
Reverse: Swaps two phases (e.g. L1, L3, L2) to reverse the motor.
3. Design:
Can be a rotary switch, toggle switch, or contact-based switch.
Often includes two contactors controlled by a selector switch or pushbuttons.
Typically has interlocking to prevent both directions from being energized at the same time.
