3. Setup and Installation
Safety First: Always disconnect power before installing or servicing electrical components. If you are unsure about any step, consult a qualified electrician.
- Mounting: The GSW-110 is designed for panel mounting. Ensure the mounting hole is 15/32 - 32 inch for a secure fit.

- Verify Connections: Double-check all wiring against your circuit diagram before restoring power.
4. Operation
The Gardner Bender GSW-110 is an ON-OFF (SPST) toggle switch. To operate:
- To Turn ON: Flip the toggle lever to the 'ON' position. This completes the circuit, allowing electrical current to flow.
- To Turn OFF: Flip the toggle lever to the 'OFF' position. This breaks the circuit, stopping the flow of electrical current.
The switch provides a clear tactile and audible click when changing positions, indicating a positive engagement.
5. Maintenance
The GSW-110 toggle switch is designed for durability and requires minimal maintenance. However, periodic inspection can prolong its lifespan and ensure safe operation:
- Visual Inspection: Regularly check the switch for any signs of physical damage, corrosion, or discoloration.
- Terminal Connections: Ensure that the screw terminals remain tight. Loose connections can lead to overheating or intermittent operation.
- Cleaning: If necessary, gently wipe the exterior of the switch with a dry, clean cloth. Do not use abrasive cleaners or solvents.
- Environmental Conditions: Ensure the switch is not exposed to conditions beyond its specified temperature and humidity ratings.
6. Troubleshooting
If you experience issues with your Gardner Bender GSW-110 switch, consider the following:
- No Power/Intermittent Operation:
- Check all wiring connections for tightness and proper insulation.
- Verify the power source is active.
- Ensure the switch is rated for the current and voltage of your application. Overloading can cause premature failure.
- Toggle Lever Stiffness: This is typically normal for heavy-duty switches, indicating a robust mechanism. If it becomes excessively stiff or stuck, inspect for foreign objects or damage.
- Overheating: If the switch feels hot to the touch, immediately disconnect power. This could indicate an overload, loose connection, or internal fault. Do not use the switch until the cause is identified and rectified.
If problems persist, contact a qualified professional or Gardner Bender customer support.
