摘要： An improved alphanumeric keyboard 10 is illustrated for use in lap top or notebook personal computers 12. The keyboard 10 has a plurality of full travel, self leveling keyswitches 14 for actuating printed circuit electrical contacts 22 and 26 when the keyswitch is depressed. The keyboard 10 includes an integral keyswitch structure 40 that has an integral keytop 42 and keytop support substructure 44 supported on a common integral base sheet 46. Each of the keytop support substructures 44 includes hinge members 50a50b, 50c and 50d that are positioned in a rectangular orientation about the keytop 42. Each hinge member has a rigid upper hinge panel 52 and a lower hinge panel 58 that are integrally interconnected to the keytop 42 and the base sheet 46 for maintaining the keytop in a parallelogram orientation as it is depressed to prevent the keytop from moving laterally or wobbling during depression. The hinge panels 52 and 58 are interconnected by resilient webs 54, 60 and 64. In one embodiment, the resilient webs return the keytop to its elevated non-actuating position. In the last-mentioned preferred embodiment, a leaf spring 208 is provided to urge the keytop back to its non-actuating rest position.
摘要翻译：示出了用于笔记本或笔记本个人计算机12的改进的字母数字键盘10.键盘10具有多个完全行进的自动调平键开关14，用于在按下钥匙开关时致动印刷电路电触点22和26。键盘10包括整体键开关结构40，其具有支撑在公共整体基片46上的整体键顶42和键顶支撑子结构44.每个键顶支撑子结构44包括铰链构件50a + B，50b，50c和50d，定位在围绕键顶42的矩形方向上。每个铰链构件具有刚性的上铰链板52和下铰链板58，它们与键顶42和基板46整体地互连，用于将键顶保持为平行四边形取向，因为它是沮丧以防止键盘在抑郁症期间横向移动或摆动。铰链板52和58通过弹性腹板54,60和64相互连接。在一个实施例中，弹性腹板使键顶返回其升高的非致动位置。在最后提到的优选实施例中，提供了板簧208以将键帽推回到其非致动静止位置。

摘要： A switch device that prevents a contact failure from occurring between electrode contact points by having a self-cleaning function is provided. When a key top 4 is pushed downward, a portion between a winding start end 7b and a winding terminal end 7c of a spiral contactor 7 is extended by an operation part 3B provided in an actuator 3. At this time, the winding start end 7c slides along the surface of a stationary electrode 5. As a result, dusts or stains attached to the winding terminal end 7c and/or the stationary electrode 5, oxide films formed on the surfaces of the electrodes, etc., is self-cleaned. Therefore, it is possible to solve a contact failure problem between the movable electrode 6 and the stationary electrode 5.

摘要： A membrane switch comprises an upper flexible layers, separation layer and a lower conductive layer mounted on a support. The membrane switch is designed to absorb the noise created when a key is depressed and an operating block collides with the layers directly beneath it. By creating several holes in the one or more of the lower layers of the membrane switch, and optionally the support that geometrically surrounds the aperture of the separation layer, the colliding force of the operating block on the laminated membrane switch is dispersed and much of the noise is absorbed.

摘要： The invention relates to an actuator for an electric push-button switch (30) comprising a housing shell (10) in whose shell opening (13) a holding plate (20) is placed. A holding suspension, together with outer stops (21) and outer counterstops (11) between the holding plate (20) and the holding housing permit the non-actuated holding plate (10) to be pressed into a defined outer position of rest (20.1). A push-button switch (30), which is arranged in the housing shell (10), is, together with its switching element (31), located in an extended position (30.1) that is effected by a switch suspension (33). The aim of the invention is to provide an economical space-saving design. To this end, the switch suspension (33) of the push-button switch (30) is simultaneously provided with the function of providing the holding suspension of the holding plate (20). Inner stops and inner counterstops are also provided between the holding plate (20) and the housing shell (10) and, in the event of an asymmetrical actuation, ensure a defined inclined position of the holding plate (20). This controlled inclined position ensures that the switching element (31) of the push-button switch (30) reaches, even in this event, a contact-effective depressed position.

摘要： A coil spring constituting a pushbutton switch includes an intermediate diameter coil spring part serving as a tension spring coil spring part serving to depress a movable contact. This reduces the number of parts being needed. In addition, a housing guides a pushbutton support arm fixedly inserted into a groove formed between the casing and a guide part and the tip end of the support arm is adapted to strike the bottom of the housing in depression of the pushbutton and is thereby stopped, while the tip end is stopped by a stopper when the support arm is returned. Moreover, a projection part of a pushbutton body is pushed into the coil spring whereby the intermediate coil spring part is elongated while the small diameter coil part is contracted for closing the contacts, the contacts thereupon being released by the return of the pushbutton.

摘要： A key switch is disclosed which employs a coil spring formed of a spring element and which has a smaller-diameter portion, a conical portion joined to one end of the smaller-diameter portion, and a larger-diameter portion joined to the other end of the smaller-diameter portion. The smaller-diameter portion has the spring element coiled at a relatively small diameter. The conical portion has the spring element extending coiled so as to increase its diameter progressively toward an open end thereof. The larger-diameter portion has a diameter larger than the diameter of the smaller-diameter portion. The conical portion is maintained under compression and the small-diameter portion is maintained in proximity to a contact area by elements of the key switch to provide a linearly increasing depression force for the key switch.

摘要： A switch assembly and method of operation comprises a housing having top and bottom ends spaced about a longitudinal axis and a selectively movable knob coupled to a plunger arrangement having a shaft that extends from inside the housing to couple to the knob. The switch assembly also comprises a printed circuit board having at least one wiper for engaging a contact extending from the plunger arrangement. A step shaft projects from the shaft of the plunger arrangement such that when a maintained mode of operation is desired by the switch assembly, the step shaft engages a retaining assembly formed by a portion of the housing, and when a momentary mode of operation is desired by the switch assembly the step shaft is positioned such that is free from engaging the retaining assembly.
