US 2018/0358191 A1 · MULTI-POLE DOME SWITCH

Abstract

Implementations of a multi-pole dome switch configured to simultaneously, or nearly simultaneously, close or open two separate circuits are provided. In some implementations, a multi-pole dome switch may comprise a tactile metal dome and a conductive insert that are separated by an insulator. In some implementations, when the dome is depressed, the dome and the conductive insert are configured to simultaneously, or nearly simultaneously, make conductive contact with two traces of a first circuit and two traces of a second circuit, respectively, positioned thereunder on a PCB. In this way, the multi-pole dome switch is able to simultaneously, or nearly simultaneously, close two separate circuits. Succinctly put, in some implementations, the multi-pole dome switch may be configured to act as a double-pole, double-throw switch.
