Abstract (en)

[origin: EP0029489A2] 1. Push-button having a key shaft (32 ; 85), which is guided in a frame (31), which is biassed in the inoperative position against its axial acutation direction and which in its operational position actuates at least one resilient contact assembly (39), and also having a switch latch (60 ; 100), which retains the key shaft (32 ; 85) in the operational position and which releases it in the event of repeated acutation and which comprises a switching gate (65) having a cardioid curve (66 ; 84) and a curve-following member which is guided in the latter, wherein the switching gate (65) and the curve-following member may be disengaged from each other in a release direction, which is substantially perpendicular to the actuation direction of the key shaft (32 ; 85) and the plane of the cardioid curve (66 ; 84), in order to release the retaining action of the switch latch (60, 100) in an externally controlled manner irrespective of the key actuation, characterizd in that the switching gate (65) or the curve-following member is mounted on a rocker (70 ; 75) which is pivoted on the frame (31) and in that the rocker (70 ; 75) is biassed in the inoperative position towards the frame (31) and may be swung horizontally against the bias through mechanical external control in the release direction.
