KCD3 Rocker Switch – 3 Pin Black | Centre Off | Copper Terminals | Cooler Switch
Control Your Cooler with Confidence
The KCD3 3-Pin Black Rocker Switch with Centre Off is a heavy-duty, snap-in panel switch engineered for precision electrical control in coolers, fans, appliances, and industrial panels. Its unique Centre Off (ON–OFF–ON) configuration gives you full directional control — making it the go-to choice for desert cooler speed control, motor reversing circuits, and multi-output switching setups.
Unlike switches fitted with iron contacts, this model comes equipped with copper terminals — offering superior electrical conductivity, reduced heat buildup, and longer contact life under repeated switching cycles.
Why Choose This Switch?
Copper Terminal Advantage Copper contacts deliver lower contact resistance and better thermal management compared to standard iron terminals. This means more reliable performance, less voltage drop, and a longer operational lifespan — especially under continuous or high-cycle use.
Centre Off Position The three-position ON–OFF–ON rocker design includes a neutral Centre Off position, which is essential for cooler speed controls, motor reversing, and applications where you need to cut power between two output circuits safely.
Heavy-Duty Black Housing Built with a rigid, high-impact black plastic (nylon-grade) housing that resists heat, pressure, and mechanical wear. Rated for approximately 10,000 switching cycles with stable performance throughout.
Snap-In Panel Mount No screws needed. Simply snap into a standard 30×22 mm panel cutout for a secure, vibration-resistant fit. Ideal for OEM appliance panels, DIY projects, and control boards.
