Quick guide from the manual
This document provides a wiring diagram and connection instructions for setting up a 2-wire winch motor. It is essential to use a 2-way centre-off spring-loaded switch rated for 12V and 5A or higher to ensure safe and correct operation.
Wiring Instructions
The system requires the following components to be connected in a specific configuration:
- Winch Motor: Connects to the A1 and A2 terminals of the switch.
- 2-Way Centre-Off Switch: Acts as the control for forward and reverse motion.
- 12V Battery: The power source, connected through a circuit breaker.
- Circuit Breaker: Must be installed between the positive terminal of the battery and the switch to protect the circuit.
Ensure all connections are secure and insulated. The wiring diagram illustrates the path from the battery positive through the circuit breaker to the switch, and the connections from the switch to the motor.
Troubleshooting
If the motor runs in the opposite direction to the switch position (e.g., it goes forward when the switch is set to reverse), you must swap the A1 and A2 connections on the switch. This will correct the polarity and the direction of the motor rotation.

Swap the A1 and A2 connections on the switch.
Before use
- Ensure the switch is a 2-way centre-off spring-loaded type.
- Verify the switch is rated for 12V and 5A or higher.
- Install a circuit breaker between the battery and the switch/motor circuit.
- Check all wire connections for security and proper contact.
Specs in practice
- Switch Rating
- Must be 12V and at least 5A to handle the motor load safely.
Images and diagrams
- The diagram shows the flow from the 12V battery through the circuit breaker to the switch.
- The switch controls the motor direction via the A1 and A2 terminals.
- The motor is connected directly to the switch terminals.
Model compatibility
- Designed for 2-wire winch motors.
- Requires a 12V power source.
