⚠️ PLEASE CHECK SIZE AND PANEL CUTOUT BEFORE ORDERING
This switch measures 21 × 15 mm (0.8" × 0.6"). It requires a 19.2 × 13.2 mm (0.76" × 0.52") panel cutout. Please review the dimensional drawing in the photo gallery to confirm it fits your application.
📋 Overview
Need a reliable three-position switch for direction control, mode selection, or circuit routing? The KCD1 SPDT Rocker Switch gives you ON/OFF/ON three-position switching with three terminals in a standard 21 × 15 mm panel-mount package — rated at 10A at 125VAC and 6A at 250VAC.
The SPDT (Single Pole, Double Throw) design connects one common terminal to either of two output terminals, with a center OFF position. This makes it ideal for motor direction control (forward/off/reverse), selecting between two circuits, or any application that needs three distinct switching states. The snap-in mounting tabs hold the switch securely in a standard rectangular panel cutout with no hardware needed.
🔧 How It Works
This is a Single Pole, Double Throw (SPDT) switch with three positions:
| Rocker Position | Connection | Typical Use |
|---|---|---|
| Rocker UP (Position I) | Common (Pin 2) connects to Pin 1 | Circuit A ON / Forward |
| Rocker CENTER (Position O) | Common (Pin 2) disconnected from both | OFF — no connection |
| Rocker DOWN (Position II) | Common (Pin 2) connects to Pin 3 | Circuit B ON / Reverse |
The center pin (Pin 2) is the common terminal. In the UP position, it connects to Pin 1. In the DOWN position, it connects to Pin 3. In the CENTER position, the common is disconnected from both — all circuits are off.
⭐ Key Features
- Three-Position Switching: ON/OFF/ON with center-off for full control
- SPDT Configuration: 3-pin Single Pole, Double Throw — one common, two outputs
- High Current Rating: 10A at 125VAC / 6A at 250VAC
- Snap-In Panel Mount: Spring tabs lock into a rectangular cutout — no screws or nuts needed
- Standard KCD1 Size: 21 × 15 mm (0.83" × 0.59") — a widely used form factor
- Durable Construction: Plastic housing with metal contact terminals
- Solder Terminals: Flat blade pins for easy soldering or push-on connectors

|---|---|---|
| Pin 1 (Top) | Output A | Connected to Common when rocker is in the UP position |
| Pin 2 (Center) | Common | The shared terminal — always connect your input/source here |
| Pin 3 (Bottom) | Output B | Connected to Common when rocker is in the DOWN position |
🎯 Applications
- Motor Direction Control: Forward / Off / Reverse switching for DC motors
- Mode Selection: Switch between two operating modes with a center-off
- Circuit Routing: Select between two circuits from a single power source
- Automotive & Marine: Accessory switching, window controls, lighting modes
- Control Panels: Equipment and instrument panel switching
- DIY Electronics: Project enclosures, custom builds, hobby applications
⚠️ Important Notes
- This is an SPDT (Single Pole, Double Throw) switch with 3 pins — not DPDT (which has 6 pins). Make sure SPDT is what your circuit requires.
- Do not exceed the rated current: 10A at 125VAC or 6A at 250VAC.
- The panel cutout size is 19.2 × 13.2 mm (0.76" × 0.52"). Measure your panel before ordering to ensure a proper fit.
- This switch is not waterproof. For outdoor or wet environments, use a waterproof-rated switch or add a protective boot.
- Ensure all wiring connections are properly insulated to prevent shorts or accidental contact.
