ABSTRACT:
The electrical terminals of a plunger switch are held in slots and extend into a housing for the switch substantially along the entire length of the housing. An electrical bridging contact operates between the terminals through movement of a plunger axially movable in the switch. A cap assembly for the housing includes a seal to seal the switch elements from the environment. Spring biased ears extend from the cap of the cup assembly and have notches which engage lugs formed on the housing to secure the cap assembly to the housing. Spring tabs extend from the housing to engage a base member to hold the switch. The spring tabs also trap the ears in their engaged position when the tabs engage the base.
