BAOMAIN 40A Rotary Cam Changeover Switch AC 660V 3-Position Latching Universal Cam Switch 4-Phase 16-Terminal SZW26-40/D404.4 1-Pack for Motor Control Reversing and Power Supply Switching

Professional Rotary Cam Changeover SwitchThis BAOMAIN SZW26 series universal changeover switch is designed for industrial electrical systems requiring precise manual control. Whether you are switching between two power sources or controlling the direction of a three-phase motor, this 40A switch delivers the reliability needed for professional environments.Simplified Installation Steps:Step 1: Prepare a 2.56" x 2.56" (65mm) panel cutout and ensure the mounting environment is de-energized.Step 2: Refer to the terminal diagram on the side of the switch body. Each of the 4 phases has 4 dedicated terminals (e.g., 1-2 and 3-4 for the first phase).Step 3: Use crimp connectors or bare wires to connect to the screw terminals. Follow the logic: Position 1 connects terminal "1-2, 5-6, 9-10", and Position 2 connects terminal "3-4, 7-8, 11-12".Step 4: Secure the switch to the panel using the provided screws and snap the handle into the 0 (OFF) position for initial testing.Note: Electrical installation should be performed by a qualified professional to ensure all wiring meets local safety codes.Application: circuit control switch, master control switch, testing equipment control switch, or change-over switch for electric welding machinery and other equipment.
