3. Product Overview

The Parts Express Key Switch is a robust, panel-mount device designed for reliable electrical control. It features a durable metal construction and a lock cylinder that accepts a flat key. The switch is supplied with two identical keys and includes a retaining nut for secure mounting and terminal lugs for electrical connections.

4. Setup and Installation

Proper installation is crucial for the reliable operation of the key switch. Follow these steps carefully:

1. Prepare Mounting Hole: The key switch is designed for panel mounting. A mounting hole with specific dimensions is required. The threaded part of the switch has an overall dimension of approximately 18.6 mm (23/32 inches). It features two flat sides, with a dimension of approximately 17.3 mm (87/128 inches) across these flats, to prevent twisting when mounted. The mounting flange diameter is approximately 23.8 mm (15/16 inches). Ensure your panel hole accommodates these dimensions for a secure, non-spinning fit.
2. Insert Switch: Insert the key switch into the prepared mounting hole from the front of the panel.
3. Secure with Retaining Nut: Thread the included retaining nut onto the switch body from the rear of the panel and tighten it securely to hold the switch in place. A lock washer (not always included) may be used for added security against spinning.
4. Wiring Connections: The switch is a Single Pole, Single Throw (SPST) type. It comes with two terminal lugs. These are typically solder lugs, not push-on. Connect your electrical wires to these terminals. Ensure all connections are secure and properly insulated.

5. Operating Instructions

Operating the Parts Express Key Switch is straightforward:

1. Insert Key: Insert one of the provided keys into the keyhole on the front of the switch. The switch features a spring-loaded door that covers the slot until the key is inserted.
2. Turn Key to ON/OFF: Turn the key clockwise or counter-clockwise to switch between the ON and OFF positions. The key will click into place for each position.
3. Key Removal: The key can be removed in both the ON and OFF positions, providing flexibility depending on your application's security requirements.

6. Maintenance

The Parts Express Key Switch is designed for durability and requires minimal maintenance.

• Cleaning: Periodically wipe the exterior of the switch with a clean, dry cloth to remove dust and debris. Avoid using abrasive cleaners or solvents.
• Inspection: Regularly inspect the switch for any signs of physical damage, loose connections, or excessive wear. Ensure the key turns smoothly and clicks firmly into position.
• Key Care: Keep the keys clean and free from obstructions. Avoid forcing the key if it feels stiff; a small amount of graphite lubricant can be applied to the key or keyhole if necessary, but avoid oil-based lubricants.

7. Troubleshooting

If you encounter issues with your key switch, refer to the following troubleshooting tips:

• Switch Not Activating:
  • Ensure the key is fully inserted and turned completely to the ON position.
  • Check all electrical connections for looseness or corrosion.
  • Verify that the power source to the circuit is active.
• Key Difficult to Turn or Remove:
  • Ensure the key is clean and free of debris.
  • Do not force the key. If stiff, try a small amount of graphite lubricant in the keyhole.
  • Confirm the switch is in a position (ON or OFF) where the key is designed to be removed.
• Switch Spinning in Panel:
  • Tighten the retaining nut.
  • Ensure the mounting hole was cut correctly to accommodate the switch's flat sides, preventing rotation.

If problems persist, contact Parts Express customer support or consult a qualified electrician.
