摘要： A key switch comprising a base, a key top arranged above the base, a pair of link members interlocked to each other and operatively engaged with the base and the key top to support the key top above the base and direct the key top in a vertical direction, a switching mechanism for selectively opening and closing an electric circuit in connection with a vertical movement of the key top. Each of the link members includes a sliding portion slidably and shiftably engaged with either one of the base and the key top. At least one elastic member is disposed between at least one of the link members and either one of the base and the key top with which the sliding portion of each link member is engaged. The elastic member exerts biasing force, relative to a displacement or shifting amount of the sliding portion, onto at least one of the link members in a direction different from, e.g., substantially orthogonal to, the vertical shifting direction of the key top. Preferably, the biasing force assumes a linear relationship with the shifting amount of the sliding portion.

摘要： A key switch includes a base, a key top arranged above the base, a pair of link members interlocked to each other to support the key top above the base and direct the key top in a vertical direction, and a switching mechanism capable of opening and closing an electric circuit in connection with a vertical movement of the key top. Each of the link members includes an engagable end region engaged with the key top. The base includes an inner peripheral surface defining an opening capable of receiving the link members. The base is provided on the inner peripheral surface with protruding wall parts located at positions respectively facing oppositely to the engagable end regions of the link members. Each protruding wall part serves to locally reduce a clearance defined between the inner peripheral surface and the engagable region of each link member when the link member is received in the opening.

摘要： A portable information processing unit, such as a personal computer, has a keyboard in which the normal, operating height of key switches is reduced to a more compact, reduced height automatically when a cover of the unit is closed and is automatically reinstated to the normal operating height when the cover is opened. Each key switch has a key top, a base, an actuating mechanism connecting the key top to the base, an elastic member and a switching layer, the elastic member extending through an opening in the base and interconnecting the key top and the switch. Depression of the key top produces movement thereof in a depressing direction and a depression force transferred through the elastic member to the switch, switching same from an off to an on state; upon release of the key top, the elastic member returns the key top to the normal position. A slide plate is positioned between the base and the switch and has an opening therein through which the elastic member extends and is moveable in reciprocating directions between first and second positions corresponding to, and in response to, movement of the cover between closed and open conditions, the slide plate, in the first position corresponding to the closed condition of the cover, causing the actuating mechanism to move the key top in the depressing direction, compressing the elastic member and reducing the height of the key switches.

摘要： A push button switch employing a dome spring switch element mounted in a vertical orientation relative to a generally horizontal orientation of a bottom support plate, and a key top and associated plunger which are mounted for limited, reciprocating vertical movement. An actuator, comprising a coil spring and a pivotally mounted lever, interconnects the plunger and the spring dome and is responsive to and converts vertical downward movement of the plunger to a horizontally directed depressing force on the dome spring for inverting the dome spring in a snap action and completing an electrical connection between inner and outer contacts mounted within the switch element and underlying the dome spring. A dome spring of rectangualr shape affords improved force versus displacement and snap action characteristics, and a contact frame providing flexible support of the inner contacts reduces impact shock and wear produced by the snap action. A locking structure provides for locked interengagement of the key top and plunger and a stepped, flexible stop absorbs shock and reduces impact noise in stopping the return movement of the plunger from a depressed to a normal condition. A direct drive connection between the plunger and the lever reduces the amount of plunger movement and depression force required to actuate the switch under abnormal load conditions. A process for fabrication of the switch element by stamping and molding steps reduces costs and improves reliability of the switch element.

摘要： A novel stroke converting mechanism for a push-button switch is disclosed. The stroke converting mechanism is for providing a push-button switch or a keyboard comprising the push-button switches with features such as low cost, low profile, and light and comfortable key touch. The stroke converting mechanism is made from a plate of metal such as 18-8 stainless steel, and fabricated by a single shot of press or by an etching of the plate in a batch process. The delineated plate is then shaped into a specified form by die press. In spite of the simple structure, the stroke converting mechanism can provide a sufficient stroke conversion ratio, e.g., about 4 mm of the key top to a displacement of about 1 mm necessary for actuating a couple of make-break contacts. And also, it reduces the necessary depression force on the key top to a half of the force required for actuating a make-break contacts, and provides a reduction in the height of a push-button switch or a keyboard as much as 3 mm or more.
