Product Features


The D8 tact switch breaks through the traditional mechanical switch and creates a softer electronic tact switch. Metal shrapnel or silicone gaskets are added inside. The buttons have a soft touch and strong resilience. They have large and small progress button structures. Ultra-thin structure, the entire panel is close to the wall, and the base ultra-thin structure reserves more wiring positions, which greatly reduces the safety problems of button ejection or panel deformation due to insufficient cable space and forced installation.
