Why Choose the KCD11 Long Leg Iron Pin Variant?
The long iron leg pins on this variant are specifically designed for PCB soldering and secure wiring harness connections, unlike standard short-leg plastic terminal versions. This makes it a preferred choice when:
- You need a secure solder joint on a custom PCB
- You’re building a permanent installation that demands vibration resistance
- You want better mechanical grip inside enclosures and control boxes
The metal (iron) pins offer superior conductivity and longevity compared to brass-plated plastic alternatives commonly sold by competitors.
Applications & Use Cases
This KCD11 mini rocker switch is widely used across industries and hobbyist builds:
- Arduino & Raspberry Pi Projects — Perfect as a main power switch for microcontroller boards
- DIY Electronics & Prototyping — Compact size fits breadboard enclosures and custom PCB panels
- Household Appliances — Water dispensers, coffee makers, treadmills, desk lamps
- Automotive & Vehicles — Auxiliary lighting, fog lamps, interior control panels
- Industrial Instruments — Control panels, test benches, low-power relay circuits
- Robotics — Motor ON/OFF control, battery kill-switches
Wiring & Installation Guide
- Insert the switch into a 14mm × 8.5mm panel cutout — it snaps firmly into place, no screws required.
- The two long iron legs can be directly soldered onto a PCB or connected via wire to your circuit.
- Pin 1 connects to your power source (Live/VCC); Pin 2 connects to your load (output/device).
- The “I” side of the rocker = ON; the “O” side = OFF.
Product Highlights
- Snap-in mounting — no screws, no tools needed
- Clearly marked ON (I) and OFF (O) positions
- Flame-retardant, wear-resistant plastic body
- Long iron pins for strong PCB solder connections
- Available in White/Red — high contrast for easy identification
- Compact 10×15mm footprint — fits tight enclosures
