Self-retaining electrical terminal

In a switch assembly comprising a housing molded of a suitable, electrically insulative, synthetic resin material and having a plurality of electrical terminals securable in place within said switch housing for corresponding electrical circuits, each of said terminals being of suitable electrically conductive sheet metal or the like and having a body portion and a connection portion, said connection portion being adapted to be electrically connected to said electrical circuits, wherein the improvement of this invention comprises:

• a portion of said housing being adapted to receive said terminal body portion for securement in said housing, said connection portion extending therefrom for connection to said electrical circuits, a plurality of slots, one for each terminal, formed in said housing portion, each of said slots having a relatively narrow portion for reception of said body portion of said terminal with said connection portion extending outwardly therefrom and an enlarged portion in communication with said narrow portion, the body portion of each of said terminals being generally planar and being receivable within said narrow slot portion and a retaining portion receivable within said enlarged slot portion, said housing portion having a base surface for each slot generally parallel to said narrow slot portion and constituting the base wall of said enlarged slot portion and a pair spaced side walls between said narrow slot portion and base wall of each slot so as to form side walls of said wide slot portion, said retaining portion of said body portion having a retaining tab bent out of the plane of said body portion, and a second tab bent out of the plane of said body portion, said second tab being spaced from said retaining tab, said terminal being insertable in sidewise direction into said slot with said planar body portion of said terminal being received in said narrow slot portion and with said retaining tab and said second tab being received within said wide slot portion, said retaining tab and said second tab each having a width somewhat less than the spacing between said side walls of said wide slot portion thereby to substantially prevent movement of said terminal relative to said slot in the plane of said narrow slot portion, said retaining tab having a height from the body portion of said terminal to the outer end of said terminal greater than the depth of said enlarged slot portion from said narrow slot portion to said base wall, said retaining tab, upon insertion in sidewise direction into said wide slot portion, being engageable with said base wall and being resiliently deformed thereby so that the free end thereof forceably engages said base wall for retaining the terminal therewithin upon the attempted withdrawal of the terminal in opposite sidewise direction.
