Cross-shaped 12.2mm nickel-plated dome switch with four-corner Metal Domes.

1.Four-Legged Support: The cross-shaped metal dome has four legs for support, ensuring stable pressing and rebound performance, which improves the reliability and durability of the button.

2.High Sensitivity: The metal dome responds quickly to pressing operations, allowing rapid completion of on-off actions.

3.Long Lifespan: Designed to withstand millions of press cycles, suitable for applications requiring frequent pressing.

4.Low Contact Resistance: Made from high-quality conductive materials, it ensures low contact resistance for stable electrical connections.

5.High Consistency: Manufactured with precision to ensure consistency in size and performance for each metal dome.

6.Clear Tactile Feedback: Provides clear tactile feedback when pressed, enhancing the user’s operational experience.

7.High Durability: Made from stainless steel and other corrosion-resistant materials, offering excellent durability and resistance to environmental changes.

8.Working Principle: The four-legged metal dome operates with the dome top as the main interface and the four extending legs as support. When the main interface is pressed by the user, the central dome on the main interface contacts the PAD on the circuit, forming a circuit with the legs, thus generating a conduction phenomenon.

9.Applications:Four-legged metal domes are widely used in remote controls, bank security tokens, POS machines, Bluetooth devices, mobile phones, walkie-talkies, digital cameras, gaming devices, talking books, transmitters, measuring instruments, keyboards, and various other fields.
