ABSTRACT:
A plunger switch is described. The switch has a carrier having a base portion. The carrier base portion has channels which receive bridge contact members. The bridge contact members are trapped in the channels by a retainer member. The carrier is inserted into a housing with a neck portion extending through an opening in a top of the housing. A clip/stop member is positioned around the neck portion. A button is then attached to the neck portion with a pin. The neck portion and clip/stop member are pushed through the opening into the housing. Spring arms on the clip/stop member spring outward inside the housing to create an up-stop for the carrier with respect to the housing.
