Abstract

1. Illuminated pushbutton having a luminaire unit (21) with a power supply unit (20), cast into a housing (14), for the luminaire unit (21) and a squareshaped or cylindrical, transparent luminaire housing (59) connected thereto for the luminaire unit (21), which in particular contains incandescent lamps, characterized in that, on at least one side laterally on the luminaire housing (59), an explosion-proof encapsulated interrupt chamber space (15, 17) with fixed and movable contact members (26, 27 ; 28, 29) is arranged, of which the switch tappet (31, 32) connected to the movable contact members (28, 29) projects out of a closing cover (52), surrounding the luminaire housing, for the explosion-proof space and, if appropriate, for the housing (14) parallel to the central axis of the luminaire housing (59) in that the luminaire housing is enclosed by a pot-shaped pushbutton element (60), which is guided so as to be displaceable relative to the luminaire housing, and in that, on at least one side of the pushbutton element (60), a projection (58, 62) is formed on which covers the switch tappet (31, 32) and interacts with the latter.
