How Does Snap Dome Work?

Snap dome silicone buttons refer to the assembly and bonding of the vulcanized silicone buttons and snap dome to form a button product that can conduct power.

The advantage of custom snap dome is that it has very good fixability, stability, resilience and conductivity, but the cost is higher than other conductive products, such as ink conductivity and black particle conductivity.

The reason why the silicone key of the guozi slice is conductive is that the film button part of the guozi slice is designed with snap dome, which is mainly made of stainless steel and has a very good conductive life. Its working principle is when the button surface is stressed. , The metal shrapnel of the snap dome is recessed to contact the PCB board to form a current loop, which is normal operation.
