The 3-leg metal dome switch is a reliable and durable tactile switch commonly used in electronic devices for user input. Its metal dome delivers a responsive touch, making it ideal for applications like keypads, remote controls, and other handheld devices. When pressed, the dome closes the circuit by acting as a conductive bridge on the PCB, ensuring accurate and immediate input.

With a long lifespan of up to millions of actuation, this switch is designed for durability and reliability. The three-leg design ensures secure mounting and stable electrical contact, while its compact and low-profile form factor makes it perfect for space-constrained designs. The metal dome also provides a satisfying “click” sound and tactile feedback, enhancing the overall user experience.

Widely used in consumer electronics, industrial control panels, and medical devices, the 3-leg metal dome switch is a cost-effective solution for tactile input. Its ease of integration into custom designs offers flexibility for developers working on a wide range of projects.
