5. Installation and Wiring
Before you begin, ensure power is disconnected at the circuit breaker.
- Identify Wires: The GSW-39 switch comes with pre-attached wire leads. Typically, these are:
- Black Wire: Common / Line Input
- Blue Wire: Load A Output
- Red Wire: Load B Output
- Remove Old Switch (if applicable): Carefully disconnect the wires from the existing switch, noting their connections.
- Connect New Switch:
- Connect the Black wire from the GSW-39 switch to the incoming power line (or the common wire from your fixture).
- Connect the Blue wire from the GSW-39 switch to the first load (e.g., one set of lights in a ceiling fan).
- Connect the Red wire from the GSW-39 switch to the second load (e.g., another set of lights or a fan motor).
- Secure all connections with appropriate wire connectors (not included). Ensure connections are tight and insulated.
- Mount the Switch: Insert the threaded portion of the switch into the designated opening in your fixture. Secure it with the provided nut (if applicable) or by tightening the brass housing.
- Attach Pull Chain: Connect the pull chain extension to the chain protruding from the switch.
- Restore Power: Once all connections are secure and the switch is properly mounted, restore power at the circuit breaker.
Refer to the wiring diagram provided with your specific fixture for detailed connection points, as configurations may vary.
6. Operation
The Gardner Bender GSW-39 switch operates in a sequential manner by pulling the chain. Each pull cycles through the following positions:
- Initial State: OFF
- First Pull: Activates Load A (ON(A))
- Second Pull: Activates Load B (ON(B))
- Third Pull: Activates Load A and Load B (ON(A+B))
- Fourth Pull: Returns to OFF state
The cycle repeats with subsequent pulls.
7. Maintenance
The GSW-39 switch requires minimal maintenance. To ensure optimal performance and longevity:
- Periodically inspect the pull chain for wear or damage. Replace if necessary.
- Ensure the switch housing and connections remain free from dust, dirt, and moisture.
- Do not apply excessive force when pulling the chain.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Switch does not operate or no power to loads. | No power to the fixture, loose wiring connection, faulty switch. | Check circuit breaker. Verify all wire connections are secure. Test switch with a multimeter (if qualified) or replace if faulty. |
| Incorrect load activation (e.g., A+B activates instead of A). | Incorrect wiring of load wires. | Review Section 5 (Installation and Wiring) and re-check connections for Blue and Red wires. |
| Pull chain is stuck or difficult to operate. | Internal mechanism obstruction, damaged chain. | Do not force the chain. Inspect for external obstructions. If internal, the switch may need replacement. |
