Black Rocker Switch ON-OFF SPST 2-Pin 21×15mm (0.8" x 0.6") KCD1-101 10A/125VAC 6A/250VAC — 2/5/10 Pack

📋 Overview

Need a simple, reliable ON/OFF switch for your project? The KCD1-101 SPST Rocker Switch gives you clean two-position ON/OFF switching with two terminals in a standard 21 × 15 mm panel-mount package — rated at 10A at 125VAC and 6A at 250VAC.

The SPST (Single Pole, Single Throw) design is the simplest switch type — it either completes or breaks a single circuit. Flip it one way and the circuit is on; flip it the other way and the circuit is off. The snap-in mounting tabs hold the switch securely in a standard rectangular panel cutout with no hardware needed. It's the go-to switch for power control, lighting, appliances, automotive accessories, and countless DIY electronics projects.

🔧 How It Works

This is a Single Pole, Single Throw (SPST) switch with two positions:

Simply wire the switch in series with your load. When the rocker is in the ON position, the two terminals are connected and current flows through the circuit. When the rocker is in the OFF position, the connection is broken and the circuit is off.

📊 Specifications

📌 Pinout

The switch has two flat blade terminals on the back:

With an SPST switch, there is no "common" or "output" — the two pins are simply the two ends of a switch contact. Wire them in series with your load in either orientation.

🎯 Applications

• Power Control: Main power ON/OFF for devices and enclosures
• Lighting: Switch lamps, LED strips, and indicator lights on and off
• Automotive & Marine: Accessory power switches for lights, fans, and pumps
• Appliances: Small appliance and equipment power switching
• Control Panels: Equipment and instrument panel switching
• DIY Electronics: Project enclosures, custom builds, hobby applications
• Arduino & Raspberry Pi Projects: External power switching for project housings

⚠️ Important Notes

• This is an SPST (Single Pole, Single Throw) switch with 2 pins — it only switches one circuit ON or OFF. If you need to select between two circuits, you need an SPDT (3-pin) switch instead.
• 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.
