ABSTRACT:
The invention is directed to a switch arrangement for signaling the movement and the inclination of the switch arrangement which is accommodated in a housing. The switch arrangement (2) includes a first switch (12) configured as an On/Off switch and a second switch (10) connected to a capacitor (K). The switches include each conductor portions (22, 24) adapted to be connected to each other by a movable actuating member (18). While the switch (12) signals both the movement and the inclination of the arrangement (2), the switch (10) signals a movement of the arrangement (2) by issuing pulse signals. In the position of the rest of the actuating member (18), none of the switches is activated. In one configuration of the switch arrangement, the actuating member is guided in a cutout whose sides extend towards each other in a converging fashion.
