Rocker Switch Drawing
What is a 3 Position Rocker Switch?
A 3 position rocker switch is a specialized electrical component designed to control two independent circuits through a single physical interface. Operating on a Single Pole Double Throw (SPDT) principle, this switch features three distinct states: ON-OFF-ON. In the central position, the circuit remains open (OFF), while the two outer positions close separate paths to direct power to different loads. The 13x19.5mm form factor is the industrial standard for "Mini" rocker switches, providing a compact yet robust solution for power management in diverse electronic environments.

Framed vs. Frameless Rocker Switches
FILN offers both "Enhanced Framed" and "Standard Classic" series. The Framed Series features an internal high-strength white frame that acts as an "exoskeleton," preventing deformation during installation in tight panels. It also provides a superior seat for waterproof covers. The Frameless Series is ideal for high-density panel layouts where space is at a premium, offering a sleek, minimalist aesthetic and optimized cost for large-scale production.
Global Applications
- Household Appliances: Coffee machines, air fryers, water dispensers.
- Industrial Control: PDU power strips, distribution boxes, test equipment.
- Medical Equipment: Centrifuges, diagnostic tools, nursing beds.
- Automotive & Marine: RV light control, bilge pumps, dashboard auxiliary switches.
Installation Guide
- Measure and cut a rectangular hole in your panel (13mm x 19.5mm).
- Insert the switch from the front of the panel until the side clips snap into place.
- Ensure the switch is flush and securely held by the clips.
- Connect wires to the 3 rear terminals using female spade connectors or soldering.
Complete 3 Pin 3 Way Rocker Switch Wiring Diagram and Guide
A 3 pin rocker switch wiring diagram is vital for projects requiring control over two separate electrical circuits. This specific configuration, commonly found in KCD1 series switches, operates as a Single Pole Double Throw (SPDT) switch with an "On-Off-On" functionality. It allows a single power source to alternate between two different devices or to remain in a central neutral position where both are disconnected.
How to Wire a 3 Pin 3 Way Rocker Switch: Step-by-Step Instructions
Wiring a 3-way non-illuminated switch involves managing a common power input and two independent output loads. Follow these steps for a correct setup:
- 1. Central Power Input (Common Pin): Connect the positive (+) wire from your power supply to the middle pin of the rocker switch. This pin acts as the common terminal that distributes power to the other two pins.
- 2. Device 1 Connection: Connect the bottom pin of the switch to the positive input of your first device (Device 1). In the "Down" position, the circuit to this device is closed.
- 3. Device 2 Connection: Connect the top pin of the switch to the positive input of your second device (Device 2). In the "Up" position, power is redirected here.
- 4. Grounding the Circuit: Connect the negative (-) terminals of both Device 1 and Device 2 directly back to the negative terminal of the power source. As this is a non-illuminated switch, the switch itself does not require a ground connection.
Switch Operation Logic Table
| Switch State | Device 1 Status | Device 2 Status |
|---|---|---|
| UP Position | OFF | ON (Active) |
| Normal (Middle) | OFF (Resting) | OFF (Resting) |
| DOWN Position | ON (Active) | OFF |
Technical Installation Considerations
- On-Off-On Functionality: This 3-pin configuration is unique because the center position acts as a complete "Off" state for both devices, making it perfect for reversing motors or toggling between two different lighting modes.
- KCD1 Series Ratings: Most KCD1 switches are rated for 6A 250VAC or 10A 125VAC. Ensure your load does not exceed these electrical specifications to prevent internal contact welding.
- Wire Termination: For high-current applications, use high-quality female spade connectors. Ensure they are snugly fitted to the 4.8mm or 6.3mm terminals to maintain low resistance and prevent heat buildup.

Industry Knowledge: Rocker vs. Push Button Switches
| Feature | Rocker Switch | Push Button Switch |
|---|---|---|
| Installation | Snap-in (Easy) | Threaded Nut (Slow) |
| Current Load | High (up to 30A) | Moderate (usually <10A) |
| Visual Status | Clear physical angle | Needs LED indicator |
How it works: A rocker switch uses a mechanical "seesaw" mechanism. When one side is pressed, the internal bridge pivots to make contact with a terminal, completing the circuit. In an ON-OFF-ON configuration, the bridge is only in contact with the central terminal in the middle position, preventing any current flow.
