A push switch contains a circuit substrate, two fixed contacts disposed on the circuit substrate, a dome-shaped spring which is disposed above the two fixed contacts and can be displaced between a first position in which the two fixed contacts are in a non-conductive state and a second position in which the two fixed contacts are in a conductive state and a conductive elastic member disposed on a surface of the dome-shaped spring facing the circuit substrate and having a surface facing the two fixed contacts. At least the surface of the conductive elastic member facing the two fixed contacts has conductivity. When the dome-shaped spring is displaced to the second position, the two fixed contacts are in the conductive state through the conductive elastic member.

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.
