User Manual for Generic Car Switch

Quick Guide

This manual provides instructions for installing and operating the Generic Car Switch. Important: This device is designed exclusively for 12V DC vehicle power systems. Do not connect to 220V AC household power. Always disconnect the negative terminal of the car battery before beginning installation to prevent short circuits or electric shock.

Product Overview and Specifications

The device is a dual-switch unit designed for automotive modification. It features a flame-retardant ABS construction.

• Input Voltage: DC 12V
• Rated Current: 1.5A
• Rated Power: 18W (Max)
• Working Temperature: -10°C to 60°C

Note: Do not exceed the rated current. High-power devices such as lights, air pumps, or light bars must be used with a relay to avoid overheating and damaging the switch.

Safety Instructions

• Disconnect the negative terminal of the car battery before installation.
• Ensure all wiring is firm and well-insulated using heat-shrink tubing or electrical tape.
• Exposed metal is strictly prohibited to prevent short circuits and fire.
• Ensure the waterproof gasket is correctly installed and compressed during installation.
• Keep the switch away from high-temperature, oil, and water areas.
• Do not disassemble or modify the internal structure of the switch.
• If the switch becomes loose, hot, smelly, noisy, or abnormal, stop using it immediately.

Installation and Wiring

Preparation: Ensure you have the necessary tools, including a screwdriver, wire stripper, heat-shrink tubing or electrical tape, and a hole punch.

Drilling and Installation:

1. Replace the blank reserved switch directly or select a suitable position and drill accurately.
2. Insert the switch from the front of the panel.
3. Install the waterproof gasket on the back, ensuring no deviation.
4. Install the washer and mounting nut in sequence.
5. Tighten moderately with a screwdriver to ensure the switch is stable and the gasket is fully compressed.

Wiring: Distinguish between positive and negative poles to avoid reverse connection. Refer to the wiring diagram for specific color-coded connections for the upper and lower switches. Wrap all connectors with heat-shrink tubing or electrical tape.

Testing and Finishing

After wiring, perform the following steps:

1. Check that all connections are firm, with no exposed wires or reverse polarity.
2. Reconnect the negative terminal of the battery.
3. Toggle the switch to test the LED indicator and the connected electrical device.
4. Check for overheating, abnormal noise, or other abnormalities.
5. Organize wires and fix the excess harness with cable ties to prevent winding and wear.
6. Paste function labels for easy identification.
7. Verify that the switch is securely installed and the waterproof gasket is properly sealed.
