ABSTRACT:
A pushbutton electrical switch assembly, having a particularly low profile and having uniform illumination, includes a lighting system within the housing of the pushbutton electrical switch assembly, the lighting system having four light diodes that are squarely arranged upon a printed circuit. Switching members in the form of microswitches together with the lighting system are arranged adjacent to each other and transversely to the direction of displacement of a pushbutton that is slidably arranged within the housing. The microswitches take a position in which the direction of movement of the actuation member and the direction of movement of the microswitches are perpendicular to each other. The printed circuit and the microswitches are fitted in a sandwich-type manner between flanges of lower and upper housing portions, with the housing portions being connected without screws.
