Micro Switch D2FC-F-7N (10M) is a high-reliability mechanical micro switch specifically engineered for demanding input applications, offering a substantial 10 million click operational life. This highly durable component features the standard 3-pin configuration (Common, Normally Open, Normally Closed) and utilizes a sensitive snap-action mechanism to deliver a crisp, tactile, and audible feedback upon actuation. You often find the D2FC-F-7N (10M) replacing standard switches in devices that experience high usage frequency, consequently, it drastically reduces the risk of double-clicking or intermittent signal failure. Therefore, designers specify this switch to enhance the performance and longevity of consumer electronics where dependability is paramount.

Key Features:

High Durability: Offers a guaranteed mechanical lifespan of 10 million cycles, significantly outlasting standard micro switches.
Tactile Feedback: The snap-action mechanism provides a clear, distinct click sensation, improving user experience and confirmation.
Rated for Low Current: Optimized for logic-level switching, making it ideal for interfacing with microcontrollers and digital circuits.
Standard Housing: Uses the common 3-pin configuration and physical dimensions, ensuring easy replacement and compatibility with existing designs.
Reliable Performance: Maintains consistent operational force and travel distance throughout its extensive lifespan.

Pinout and Wiring:

Pin 1 (C – Common): Connect the input signal or power source to this pin.
Pin 2 (NO – Normally Open): The circuit is open when the switch is unactuated; it closes when the button is pressed.
Pin 3 (NC – Normally Closed): The circuit is closed when the switch is unactuated; it opens when the button is pressed.
Wiring Note: You only need to use the Common pin and either the NO or NC pin, depending on the required switching logic. Furthermore, ensure you debounce the switch signal in software or hardware for reliable digital input.
