With its 4-pin configuration, this switch can simultaneously break two independent circuits with a single toggle — making it ideal for controlling both the positive and negative lines of a DC circuit, or switching a live line plus an indicator light. Its miniature 21×15mm form factor and snap-in mounting make it easy to install in control panels, enclosures, and DIY electronics projects.\u003c\/p\u003e\n\u003ch2\u003e⭐ Key Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDPST On\/Off Operation\u003c\/strong\u003e – Switches two circuits simultaneously with a single toggle action\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Voltage Rating\u003c\/strong\u003e – Rated for 6A at 250VAC and 10A at 125VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSnap-In Panel Mounting\u003c\/strong\u003e – Installs quickly into a standard rectangular panel cutout (approx. 18×13mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Form Factor\u003c\/strong\u003e – Miniature 21×15mm body fits tight spaces and small enclosures\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4.8mm Blade Terminals\u003c\/strong\u003e – Compatible with standard quick-connect spade connectors for solderless wiring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction\u003c\/strong\u003e – Rugged nylon housing with copper alloy contacts for reliable switching\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Position Latching\u003c\/strong\u003e – Bistable On\/Off positions with a satisfying tactile click\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e📋 Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eKCD1-H-4P2D-10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSwitch Type\u003c\/td\u003e\n\u003ctd\u003eRocker Switch (DPST)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit Configuration\u003c\/td\u003e\n\u003ctd\u003eDouble Pole Single Throw (DPST)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePositions\u003c\/td\u003e\n\u003ctd\u003e2 (On\/Off)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Pins\u003c\/td\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Voltage\/Current\u003c\/td\u003e\n\u003ctd\u003e6A @ 250VAC \/ 10A @ 125VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Type\u003c\/td\u003e\n\u003ctd\u003e4.8mm Blade (Spade)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eSnap-In Panel Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePanel Cutout\u003c\/td\u003e\n\u003ctd\u003e~19 × 13mm (rectangular)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Dimensions\u003c\/td\u003e\n\u003ctd\u003e21 × 15 × 24mm (L × W × H)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHousing Material\u003c\/td\u003e\n\u003ctd\u003eNylon (PA66)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContact Material\u003c\/td\u003e\n\u003ctd\u003eCopper Alloy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-25°C to +85°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003e🔧 How It Works\u003c\/h2\u003e\n\u003cp\u003eThe KCD1 is a \u003cstrong\u003eDPST (Double Pole Single Throw)\u003c\/strong\u003e switch, which means it controls \u003cstrong\u003etwo separate circuits\u003c\/strong\u003e at the same time using a single rocker toggle.
