A miniature insert molded slide (10) or rocker (12) switch assembly is designed for machine insertion on printed circuit boards. A metallic strip (90) is blanked to form pairs of oppositely disposed terminals (22) still attached to the carrier strip (92). The insert-molding operation forms a box-like housing (14) about the terminals (22) on the strip (90), each pair of terminals (22) being embedded in the base (16) of said housing (14). During the insert-molding operation, the die forms the terminal head (28) of each terminal (22). The housing-terminals construction is utilized for both the slide (10) and rocker (12) switch assemblies. The slide switch assembly (10) includes an actuator (40) having a double cantilevered resilient contactor (50) entrapped in a through opening (48) in the actuator (40), the contactor (50) having a depending arcuately shaped contactor head (54) for engaging and disengaging the terminal heads (28). The rocker switch assembly (12 ) includes an actuator (60) having a through opening (66) and double cantilevered contactor (50) and has upward angled extensions (64) and lateral projections (70) from the sides of the actuator (60). The lateral projections (70) comprise pie-shaped shafts (70), the bottom portion (72) being arcuately shaped for slideable engagement with the top of transverse housing walls (19), and the point comprising a pivot (74).
A miniature slide switch assembly comprising a box-like housing having a base, side walls, and a plurality of transversely extending walls forming individual chambers therein, a plurality of apertures extending between the upper and lower surfaces of said base and communicating with said chambers, a plurality of terminals secured to said base, said terminals disposed in pairs of oppositely disposed terminals with one pair in each of said chambers, each of said oppositely disposed terminals including an arcuate shaped terminal head disposed over one of said apertures and a longitudinal portion embedded in the upper surface of said base and extending outwardly of said housing, a plurality of actuators each disposed in one of said chambers and including an upwardly extending post and a longitudinal passage formed in the subsurface of said actuator, a plurality of double cantilevered contactors each comprising a reversely bent contactor arm integral with an arcuately shaped contactor head, each of said contactors having its reversely bent contactor arm disposed in a respective one of said passages to fixedly secure the contactor within a respective actuator, and a cover having a plurality of apertures therein, each of said posts projecting through a cover aperture for actuation of the respective slide switch.
A miniature rocker switch comprising a box-like housing comprising a base having an upper surface and a lower surface and upwardly extending walls about the perimeter of said base and a plurality of transversely extending walls forming chambers therein, said base having a plurality of apertures communicating with the upper and lower surfaces of the base at a respective chamber, a plurality of oppositely disposed terminals, each terminal embedded in said base and having a longitudinal portion and at end thereof a dome-shaped terminal head disposed over one of said apertures and another end of the terminal extending outwardly of said housing to form a second portion, a plurality of actuators each having an upward extension, a longitudinal passage at the undersurface therein extending through the actuator, transverse projections each having an arcuate portion extending from a respective side of said actuator, each of said actuators disposed in one of said chambers with the arcuate portion of each of said transverse projections resting upon a transversely extending wall thereof for slideable engagement therewith, a double cantilevered arm comprising a reversely bent first portion integral with a downwardly extending arcuate portion, said reversely bent first portion disposed in said passage to fixedly secure the arm within a respective actuator, and a switch cover having a plurality of apertures for receiving upward extensions therein and a plurality of transverse walls each having a cut-away portion for securing said transverse projections, said transverse projections received in said cut-away portions such that rotation of said actuator produces slideable engagement of said arcuate portions with the respective transversly extending walls to effect slideable engagement and disengagement of said downwardly extending arcuate portion with said oppositely disposed dome-shaped terminal heads.
