  • Patent number: 11948758
    Abstract: 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.
    Type: Grant
    Filed: January 17, 2023
    Date of Patent: April 2, 2024
