The KCD3 series is a rectangular, snap-in component designed for panel mounting. As a 2-pin SPST (Single Pole Single Throw) device, it provides a simple binary control—connecting the power in the \"ON\" position and completely isolating the load in the \"OFF\" position. It is the most common control element in power systems for safety and operational efficiency.\u003c\/p\u003e\n\u003cdiv style=\"margin-top: 40px;\"\u003e\n\u003ch2 style=\"color: #1a73e8; font-weight: bold; display: inline-block; margin-bottom: 2px;\"\u003eProduct Overview\u003c\/h2\u003e\n\u003cdiv style=\"border-bottom: 2px solid #1a73e8; width: 100%; margin-bottom: 15px;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003eThe \u003cstrong\u003eFL3-KCD3-0111-11X\u003c\/strong\u003e is a high-performance \u003cstrong\u003eon and off rocker switch\u003c\/strong\u003e characterized by its universal KCD3 rectangular form factor.
