Always disconnect power before installing or servicing any electrical components. Improper installation can lead to electrical shock, fire, or damage to the product and vehicle. Ensure all wiring connections are secure and insulated. This product is designed for 12V-24V DC systems only. Do not exceed the rated current (20A at 12V DC, 10A at 24V DC).

If you are unsure about any part of the installation process, consult a qualified electrician or automotive technician.

2. Product Overview

The Nilight 3-Way Rocker Switch (Model 90741B) allows you to control a single electrical load (such as a light) from two separate locations. This is commonly used in vehicles like RVs, campers, trucks, boats, UTVs, and ATVs where convenient control from multiple points is desired. The switch features a durable, waterproof design for reliable performance in various environments.

5.2 Wiring Diagram

The Nilight 3-Way Rocker Switch is designed to control a single load from two locations. A typical 3-way switch setup involves two switches and a load. The switches connect to the power source and the load using common and traveler wires.

IMPORTANT WIRING NOTE: Customer feedback indicates that the wiring diagram provided with the product may be incorrect or misleading, potentially causing short circuits if followed precisely. For a standard 3-way switch configuration:

• The positive (+) battery wire should connect to the common terminal (often marked '3' or 'Input') of the first switch.
• The positive (+) load wire (to the device being controlled) should connect to the common terminal (often marked '3' or 'Output') of the second switch.
• The two traveler wires connect the remaining terminals (often marked '1' and '2' or '4' and '5') between the two switches.
• The negative (-) wire from the battery should connect directly to the negative (-) terminal of the load and does not typically connect to the switch terminals in a standard 3-way setup.

Always verify your wiring with a multimeter before applying power. If you encounter issues or are uncertain, consult a professional or refer to reliable automotive electrical guides for 3-way switch wiring.

6. Operation

Once properly installed and wired, the Nilight 3-Way Rocker Switch allows for simple control of your connected device. Pressing the rocker switch on either switch will change the state of the connected load (e.g., turn a light ON or OFF), regardless of the position of the other switch. This provides convenient control from two separate points within your vehicle.

7. Maintenance

The Nilight 3-Way Rocker Switch is designed for durability and is IP65 waterproof rated. Regular maintenance is minimal:

• Cleaning: Wipe the switch surface with a damp cloth to remove dirt or debris. Avoid using harsh chemicals or abrasive cleaners.
• Inspection: Periodically check the wiring connections to ensure they remain secure and free from corrosion.
• Environmental Protection: While waterproof, prolonged submersion is not recommended. Ensure the switch is properly sealed in its mounting location.

8. Troubleshooting

• Switch Not Functioning:
  • Check all wiring connections for looseness or corrosion.
  • Verify that power is supplied to the circuit.
  • Confirm the load (e.g., light bulb) is operational.
  • Re-examine the wiring against the corrected 3-way switch principles mentioned in Section 5.2.
• Short Circuit or Blown Fuse:
  • This is often caused by incorrect wiring. Immediately disconnect power.
  • Carefully review the wiring diagram and ensure all connections are correct, especially the negative wire not being connected to the switch terminals.
  • Replace any blown fuses only after correcting the wiring issue.
• Intermittent Operation:
  • Check for loose connections or damaged wires.
  • Ensure the switch is securely mounted and not experiencing physical interference.
