4. Setup and Installation
The KCD1-8-101NW switch features a snap-in design for straightforward installation. Ensure the power source is disconnected before proceeding with installation.
4.1 Mounting
- Prepare the Mounting Hole: Drill a round hole with a diameter of 20 mm (0.78 inches) in the desired mounting surface. Ensure the material thickness is appropriate for a secure snap-in fit.
- Insert the Switch: Gently push the switch into the prepared hole. The snap-in tabs on the sides of the switch body will secure it in place. Apply even pressure to avoid damaging the switch or the mounting surface.

4.2 Wiring
The switch has three pins for connection. It is a Single Pole Single Throw (SPST) switch with an integrated LED. The pins are typically configured as follows:
- Pin 1 (Input): Connect to the positive (+) terminal of your 12V DC power source.
- Pin 2 (Output): Connect to the positive (+) terminal of the device or load you wish to power.
- Pin 3 (Ground/LED Negative): Connect to the negative (-) terminal of your 12V DC power source or chassis ground. This pin also provides the ground connection for the internal LED.
Ensure all connections are secure and properly insulated to prevent short circuits. Verify the correct polarity before applying power.

5. Operating Instructions
Operating the APIELE KCD1-8-101NW switch is straightforward:
- To Turn ON: Press the rocker switch to the 'ON' position. The integrated LED will illuminate, indicating that power is flowing to the connected device.
- To Turn OFF: Press the rocker switch to the 'OFF' position. The LED will turn off, and power to the connected device will be interrupted.
The tactile feedback of the rocker ensures clear indication of the switch's state.
6. Maintenance
The APIELE KCD1-8-101NW switch is designed for durability and requires minimal maintenance.
- Cleaning: Periodically wipe the switch surface with a soft, damp cloth to remove dust and grime. Avoid using harsh chemicals or abrasive cleaners, as these can damage the plastic and waterproof seal.
- Connection Check: Occasionally inspect the wiring connections to ensure they remain secure and free from corrosion. Loose connections can lead to intermittent operation or overheating.
- Waterproof Integrity: While the switch is IP65 rated for water resistance, avoid prolonged submersion or high-pressure water jets, which could compromise the seal over time.
7. Troubleshooting
If you encounter issues with your APIELE KCD1-8-101NW switch, consider the following troubleshooting steps:
- Switch Not Activating Device:
- Check the power source: Ensure 12V DC power is supplied to Pin 1.
- Verify wiring: Confirm that Pin 1 (Input), Pin 2 (Output), and Pin 3 (Ground) are correctly connected.
- Inspect the load: Ensure the connected device is functioning correctly and not drawing excessive current.
- Check for blown fuses: If applicable, verify that any inline fuses in the circuit are intact.
- LED Not Illuminating:
- Ensure the switch is in the 'ON' position.
- Verify the ground connection: Confirm Pin 3 is properly connected to ground.
- Check for correct voltage: The LED requires 12V DC to operate.
- LED failure: In rare cases, the LED itself may be faulty.
- Intermittent Operation:
