摘要： A key switch comprises a casing, at least one key slide guided in the cas against the force of a spring and at least one J-shaped leaf spring having a long spring arm and a short spring arm connected to the long arm by a curved intermediate part, the leaf spring being clamped to assume a unilateral curvature between two abutments, one fixed and the other moveable, the leaf spring having the free end of its long spring arm supported in a first abutment in the key slide and its curved intermediate part in a second abutment formed in a fixed contact member provided in the casing. For providing a minimum space the leaf spring is mounted parallel to the sliding direction in an elongated recess of the key slide.

摘要： A push button switch (3) encounters, during a stroke of a push rod (6) thereof, a pressure point (D), a switching (contact-making) movement, and a return tension. A one-piece spring element (16) is provided for achieving this with an uncomplicated structure, with a short stroke, and with a reliable contact once the pressure point has been overcome. The one-piece spring element has, between a contact arm (26) and a return arm (21), hairpin-shaped bent guide legs (17, 18). A sloping step (24) formed on at least one of the guide legs creates the pressure point.

摘要： A pushbutton switch comprising a housing within which a pushbutton can moveith respect to a housing socket is described. Within the housing is placed a switch plunger which moves longitudinally and can also pivot through a small angle. A contact bridge, which can be pivoted in an oversprung fashion between two fixed contacts, is disposed in the housing. The placement of the contact bridge is governed by a switch rocker, which is arranged in a hinged fashion in the housing. This allows the switch plunger and switch rocker to engage. The counterbearing for the contact bridge consists of a knife-edge bearing in the switch rocker. Between the switch plunger and the switch rocker is a return spring, arranged so that in the rest position of the pushbutton, the switch plunger occupies a pivoted position remote from the middle position. The cross motion of the switch plunger is halted, depending on the direction of motion of the pushbutton, by a constraining guide on each side.
摘要翻译：一种按钮开关，其包括壳体，其中按钮可相对于壳体插座移动到该壳体内。在壳体内设置一个开关柱塞，该开关柱塞可以纵向移动，并且还能够以小角度枢转。可以在两个固定触点之间以超调方式枢转的接触桥设置在壳体中。接触桥的放置由开关摇杆控制，开关摇杆以铰接方式布置在壳体中。这允许开关柱塞和开关摇杆接合。接触桥的支座由开关摇臂中的刀刃轴承组成。在开关柱塞和开关摇杆之间是复位弹簧，其布置成使得在按钮的静止位置，开关柱塞占据远离中间位置的枢转位置。取决于按钮的运动方向，开关柱塞的横向运动由每侧的约束导向器停止。
