Abstract:
1. An electrical switch device with a contact system ( 3 ) comprising at least one movable sliding contact ( 19 ) and at least one first fixed contact ( 4 ) and a second fixed contact ( 5 ) as well as a movable actuator ( 7 ) for switching the contact system ( 3 ), wherein the sliding contact ( 19 ) is movable during the switching of the contact system ( 3 ) such that it adjoins to the first fixed contact ( 4 ) in a first switch position and to the second fixed contact ( 5 ) in a second switch position, wherein the contact system ( 3 ) resiliently preloads the sliding contact ( 19 ) against the first fixed contact ( 4 ) in the first switch position and against the second fixed contact ( 5 ) in the second switch position, wherein the actuator ( 7 ) moves the sliding contact ( 19 ) mainly linearly from the first switch position to the second switch position in case of pressurization, wherein in the first switch position, the actuator ( 7 ) adjoins to a snap-action element ( 11 ) having a stable position and actuates the latter from its stable position to an unstable position when switching over to the second switch position, wherein the snap-action element ( 11 ) returns to the stable position upon completion of pressurization by means of the actuator ( 7 ), wherein the contact system ( 3 ) has a spring part ( 18 ) with first and second ends, the spring part first end is arranged at the sliding contact ( 19 ), the spring part second end is fixed to a post-shaped part ( 17 ), wherein the post-shaped part is mounted in a base element ( 15 ) and extends from one side of the base element ( 15 ) to enable the spring part second end to be fixed thereto, and wherein the post-shaped part ( 17 ) forms a connecting part ( 8 ) extending from the base element ( 15 ) on an opposite side of the base element ( 15 ).
