Title:
PUSH SWITCH
Document Type and Number:
Japanese Patent JP2021174715
Kind Code:
A
Abstract:
To provide a push switch that can reduce the contact noise when a push switch 1 is turned on and suppress an increase in electrical resistance of the electrical connection between two fixed contacts.SOLUTION: A push switch 1 includes a circuit board 3, two fixed contacts 4a and 4b provided on the circuit board 3, a dome-shaped spring 6 that can be displaced between a first position where the spring is located above the two fixed contacts 4a and 4b, and the two fixed contacts 4a and 4b are in the non-conducting state, and a second position where the two fixed contacts 4a and 4b are in the conductive state, and a conductive elastic member 7 provided on the surface of the dome-shaped spring 6 facing the circuit board 3. At least the surfaces of the conductive elastic member 7 facing the two fixed contacts 4a and 4b have conductivity. When the dome-shaped spring 6 is displaced to the second position, the two fixed contacts 4a and 4b are brought into a conductive state via the conductive elastic member 7.SELECTED DRAWING: Figure 4
