US 12,547,203 B1 · Button structure

Abstract

A button structure includes a circuit board, an elastic element mounted on the circuit board, a hollow base mounted to a top of the elastic element, a directional pad mounted on the base, a metal sheet connected to an inner surface of the directional pad, and a conductive elastic monomer. The conductive elastic monomer is disposed in the directional pad. The conductive elastic monomer is disposed in a middle of the base. A top end of the conductive elastic monomer is connected to the metal sheet, and a bottom end of the conductive elastic monomer has a connecting end extending downward. The bottom end of the conductive elastic monomer is connected to the elastic element. The connecting end passes through the elastic element and the circuit board. The circuit board is electrically connected to the connecting end.
