ABSTRACT:
A push switch includes a central contact member arranged on a contact support member with an annular peripheral contact member surrounding the central contact member. An elastic conductive member such as a belleville spring and the peripheral contact member along their entire outer edge portions are fixedly held within an insulating case in a manner to seal the space around the central contact. In addition, an elastic spring member may be provided in a position covering the elastic conductive member. A plurality of the push switches may easily be manufactured on an assembly line by forming a multiplicity of central contacts, peripheral contacts and conductive members in separate processes and sequentially going through a first and second insert molding processes.
