Patent ID: 7569786

Claim:
Actuator for an electric push-button switch ( 30 ), particularly in motor vehicles, with a housing shell ( 10 ) with a shell opening ( 13 ) for holding the push-button switch ( 30 ), with a handle plate ( 20 ) aligned with the switch opening ( 13 ) for manual actuation ( 28 ), with a handle suspension for pushing the handle plate ( 20 ) back into an outer, unactuated rest position ( 20 . 1 ), with outer stops ( 21 ) on the handle plate ( 20 ), on the one hand, and outer opposing stops ( 11 ) on the housing shell ( 10 ), on the other hand, which determine the outer rest position ( 20 . 1 ) of the suspended handle plate ( 20 ), wherein the handle plate ( 20 ) is movable back into an inner operative position ( 20 . 2 ) when actuated ( 28 ) against its handle suspension, with a pressure-actuated switching element ( 31 ) on the switch housing ( 32 ), which is pushable out by a switch suspension ( 33 ) into an extended position ( 30 . 1 ), wherein, in the extended position ( 30 . 1 ), the handle plate ( 20 ) is in its rest position ( 20 . 1 ), and the contacts in the push-button switch ( 30 ) are in a first switching position, and when the handle plate ( 20 ) is actuated ( 28 ), the switching element ( 31 ) moves against its switch suspension ( 33 ) into a depressed position ( 30 . 2 ), in which its contacts are in a second switching position, wherein the switch suspension ( 33 ) of the push-button switch ( 30 ) is simultaneously the handle suspension for the handle plate ( 20 ), which causes the unactuated handle plate ( 20 ) to be held by the switch suspension ( 33 ) of the push-button switch ( 30 ) in its outer rest position ( 20 . 1 ), in which the outer stops ( 21 ) of the handle plate rest on the outer opposing stops ( 11 ) of the housing shell ( 10 ), and that the handle plate ( 20 ) has inner stops ( 22 ) and the housing shell ( 10 ) has inner opposing stops ( 12 ), which, when the handle plate ( 20 ) is unsymmetrically actuated ( 29 ), cause the handle plate ( 20 ) to assume an inclined position ( 20 . 3 ) in such a way that the switching element ( 31 ) of the push-button switch ( 30 ) is nevertheless moved by the handle plate ( 20 ) into its depressed effective contact position ( 30 . 2 ).
