Triangle Dome Switch

1. Introductionc to Square Dome Switch

The Square Dome Switch (square metal dome) is a type of conductive element in the metal dome switch family characterized by its square design, offering stable pressing force and excellent tactile feedback.

Precision-stamped by SHANYO Precision Electronics from high-quality SUS301 high-elasticity stainless steel, its precise structure and smooth edges and corners ensure consistent conduction performance even during high-frequency operation.

The square structure not only improves force uniformity but also provides better compatibility with certain special button designs and mechanical layouts. We offer a variety of side lengths and contact force options and support OEM/ODM customization to meet the needs of various end devices.
