Four Legs Dome Switch

1. Introduction to Four Leg Dome Switch

Four-Leg Dome Switches (four-leg metal domes/four-leg metal conductive plates) are key touch-sensitive components in membrane switches and various pushbutton switches. Shanyo’s Four-Leg Dome Switches are stamped from stainless steel, featuring a stable four-corner support structure, ensuring a clear click feel and reliable conduction when pressed.

This series includes a variety of shapes, from conventional round and square to special shapes (such as the SY01 and SY02 series). Gold-plated versions are also available, meeting the requirements for high reliability and corrosion resistance, making them suitable for long-term use in precision electronic products.
