10-Pin Rocker Switch Wiring Diagram
A comprehensive guide to correctly wiring your 10-pin rocker switch, featuring detailed diagrams and step-by-step instructions from WEUP, your reliable partner in premium switch manufacturing.
Understanding the 10-Pin Rocker Switch
A 10-pin rocker switch is a versatile component commonly used in automotive, marine, industrial control panels, and household appliances for controlling multiple circuits or functions. The 10 pins allow for complex switching configurations such as On-Off-On, (On)-Off-(On), or controlling independent circuits with a single actuator.
Proper wiring is crucial for safety and functionality. This guide provides clear diagrams and descriptions to help engineers, technicians, and DIY enthusiasts achieve reliable connections.
Standard 10-Pin Layout & Pin Identification
Pin Configuration (Bottom View):
- 1 Common Terminal 1 (C1)
- 2 Normally Open 1 (NO1)
- 3 Normally Closed 1 (NC1)
- 4 Common Terminal 2 (C2)
- 5 Normally Open 2 (NO2)
Pin Configuration (Continued):
- 6 Normally Closed 2 (NC2)
- 7 Illumination Anode (+)
- 8 Illumination Cathode (-)
- 9 Auxiliary Terminal (if applicable)
- 10 Ground/Frame
Note: Always refer to the specific datasheet for your WEUP switch model as pin assignments can vary slightly between designs (e.g., DPST, DPDT configurations).

Detailed Wiring Diagrams
Diagram 1: Basic DPDT (Double Pole Double Throw) Configuration
This is the most common configuration for a 10-pin rocker switch, allowing control of two separate circuits with On-Off-On functionality.
Wiring Instructions:
- Power Input: Connect your positive power source (e.g., +12V) to both Common terminals C1 (Pin 1) and C2 (Pin 4).
- Load Connection – Position 1: When the switch is toggled to the first ON position, C1 connects to NO1 (Pin 2) and C2 connects to NO2 (Pin 5). Connect your Load 1 to NO1 and Load 2 to NO2.
- Load Connection – Position 2: When toggled to the opposite ON position, C1 connects to NC1 (Pin 3) and C2 connects to NC2 (Pin 6). Connect alternate Loads 3 and 4 to these pins if needed.
- Illumination: Connect Pin 7 (Anode +) to a switched or constant positive source (often via a resistor). Connect Pin 8 (Cathode -) to ground. The LED will illuminate when power is applied.
- Ground: Connect Pin 10 (Frame Ground) to the chassis or common ground point for safety and EMI reduction.
💡 Application: Perfect for controlling two motors (forward/reverse) or selecting between two power sources (e.g., Battery 1 / Battery 2).
Diagram 2: Independent On-Off Control for Two Circuits
This setup uses the switch as two completely independent SPST switches in one housing, controlling two circuits with a simple On/Off action.
Wiring Instructions:
- Circuit 1: Connect power source to C1 (Pin 1). Connect your first device (e.g., light) to NO1 (Pin 2). Leave NC1 (Pin 3) unused or insulated.
- Circuit 2: Connect the same or a different power source to C2 (Pin 4). Connect your second device (e.g., fan) to NO2 (Pin 5). Leave NC2 (Pin 6) unused.
- Illumination Options:
- Independent Illumination: Wire LED pins (7 & 8) to an independent circuit so the light is always on when the vehicle/device has power.
- Switched Illumination: Wire the LED anode (Pin 7) to the output of one of the circuits (e.g., NO1) so it only lights when that circuit is active.
- Ensure all device negatives are connected to the system ground.
⚙️ WEUP Advantage: Our switches feature silver-plated contacts for minimal voltage drop across independent circuits, ensuring both devices receive full power.
Troubleshooting Common Wiring Issues
Quick reference guide to diagnose and solve common problems with 10-pin rocker switch installations.
Switch gets hot
Indicates excessive current or poor connection.
- ✓ Check load amperage vs. switch rating (e.g., 20A max).
- ✓ Ensure wire gauge is sufficient (e.g., 12 AWG for 20A).
- ✓ Tighten all terminal screws.
LED doesn’t light
The illumination circuit is not complete.
- ✓ Verify polarity (Pin 7 = Anode +, Pin 8 = Cathode -).
- ✓ Check for a built-in resistor; add one if needed (e.g., 1kΩ for 12V).
- ✓ Test with a multimeter for voltage at pins 7 & 8.
Only one position works
Miswiring of the common or load terminals.
- ✓ Confirm power is connected to both C1 and C2 for DPDT.
- ✓ Verify loads are connected to correct NO/NC pins.
- ✓ Inspect for bent pins inside the switch housing.
