Abstract (en)
[origin: EP0118599A1] 1. A push button switch having a pot-shaped housing (1) which is open on one side, which comprises a housing base (2) and housing walls (3) and in which there may be moved a switching slide (4), in which there are arranged cooperating fixed contacts (5) and contact elements (7) which are pivoted on fixed terminal pieces (6), which are formed as double-armed levers and which through actuation of the switching slide (4) may be displaced suddenly, of which in each case the first arms (8) act together with the fixed cooperating contacts (5) and the second arms (9) are operatively connected with the switching slide (4) by means of notches (10) provided in the latter and thereby form a first bearing of the switching slide (4), having a coil pressure spring (11) which serves as a spring mechanism and to produce the contact pressure and which forms a second bearing for the switching slide (4) as it acts on the side of the switching slide (4) remote from the notches (10)-holding said slide at a distance from the front wall of the housing - and with its first end is supported on the base of a cavity (13) of a pot-shaped central portion (14) of the switching slide (4) which is arranged as a projection between the notches (10), having a sliding key (15) coupled with the switching slide (4), characterized in that the sliding key (15) has a stop device in which a stop member is guided in a heart-shaped connecting link of the sliding key (15), in that a first slide bearing is formed for the spring-loaded sliding key (15), which is provided with an actuating button, as the actuating button (18) is guided on a hollow attachment (19) which is pre-formed on the front wall (12) of the housing (1) and which projects into a recess (20) of the actuating button (18), in that the coil pressure spring (11) travels through an opening in the front wall (12) of the housing and the allow attachment (19) and is supported at its second end on the base of the recess (20) of the actuating button (18) and in that the second slide bearing of the sliding key (15) is formed by at least one pre-formed stop tongue (21) which extends crosswise in respect of the longitudinal direction of the sliding key and which is guided in a displaceable manner in an elongate recess (22) of a dividing wall piece (23) of the housing after snap engagement.
