6.2 Wiring Instructions
The RT1321 is a DPDT (Double Pole Double Throw) switch with 6 screw terminals. This configuration allows for controlling two separate circuits or reversing polarity in a single circuit. Refer to the diagram below for typical wiring connections. Always ensure power is disconnected before wiring.

For specific application wiring, consult relevant electrical diagrams. The DPDT ON/ON functionality means that when the toggle is in one extreme position, one set of contacts is closed, and when in the other extreme position, a different set of contacts is closed. There is no central OFF position.

7. Operating Instructions
The BAOMAIN RT1321 is an ON/ON toggle switch. This means it has two stable operating positions:
- Position 1 (ON): When the toggle lever is pushed to one side, the switch activates the circuit connected to that position.
- Position 2 (ON): When the toggle lever is pushed to the opposite side, the switch activates the circuit connected to that second position.
There is no neutral or "OFF" position in the center. The switch will remain in the last selected ON position until manually moved again. Ensure the desired circuit is connected to the appropriate terminals for each ON state.

8. Maintenance
- Cleaning: Keep the switch clean and free from dust and debris. Use a dry, soft cloth for cleaning. Avoid using liquid cleaners directly on the switch.
- Inspection: Periodically inspect the wiring connections to ensure they are secure and free from corrosion. Check the switch body for any signs of physical damage.
- Environment: Ensure the switch is operated within its specified temperature range and in an environment free from excessive moisture or corrosive substances.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Switch does not activate circuit. | No power to the circuit, incorrect wiring, faulty connection, or damaged switch. | Verify power supply. Check all wiring connections for correctness and security. Inspect terminals for corrosion. Test the switch with a multimeter if possible. |
| Switch feels loose or wobbly after installation. | Mounting nut not tightened sufficiently. | Ensure the mounting nut is securely tightened. Avoid over-tightening the terminal screws, as this can affect the internal mechanism. |
| Intermittent operation. | Loose wiring, internal damage, or excessive wear. | Check all wiring connections. If connections are secure, the switch may be worn out and require replacement. |
10. Applications
