摘要： The membrane is a sandwich of three dielectric layers 3, 5, 4 bonded together by adhesive films 21 with openings 22 in the intermediate layer 5 at each key position. Conductive pads 8, 18 on the inner surface of the outer layers 3, 4 face each other across the opening 22 and register with a conductive pad 20 on the outer surface of the layer 4. The pads 8 are connected in columns by conductive tracks 24 to a pulse generator 38 which pulses the columns sequentially. The pads 20 are connected in rows by conductive tracks 28 to a multipled analog to digital converter 42. The capacitance at a key position is made up of the fixed capacitance between the pads 18, 20 on the layer 4 and the capacitance between the opposed pads 8, 18, which is increased by local pressure on the layer 3.

摘要： An improved membrane switch (10). The switch (10) includes a pair of transparent, laminar contacts (16, 18) sandwiching a spacer (30) formed therein so that the contacts (16, 18) can be engaged at the location of the window (36) by the application of pressure to one of the contacts (16, 18). Engagement of the contacts (16, 18) closes a circuit to effect a desired function. With this structure, the problem of back lighting method without distortion of the indicia being caused by silver conductive ink circuit of the prior art is eliminated.

摘要： An apparatus (such as a keyboard) has a plurality of keycaps and a corresponding light guide film disposed on the underside of those keycaps. The light guide film has a periphery, and at least portions of that periphery are thicker than in an interior portion of the light guide film. So configured, more light can be made available for backlighting purposes in the thicker portions than at the thinner portions. These teachings include determining the various (different) thicknesses to employ for the light guide film based upon desired backlighting of one or more of the plurality of keycaps.

摘要： A keyswitch includes a base, a circuit board, a resilient support member and a key cap. The circuit board is disposed on the base and has a switch. The resilient support member is disposed on the circuit board. The resilient support member includes a trigger portion, a resilient portion and a support portion, wherein the resilient portion connects the trigger portion and the support portion, and the trigger portion faces the switch on the circuit board. The key cap is disposed on the resilient support member. The support portion of the resilient support member supports the key cap over the base. When the key cap is pressed, the trigger portion of the resilient support member triggers the switch and the resilient portion provides an elastic force for the key cap.

摘要： A movable contact point made of a thin conductive metal sheet in an approximate dome shape is attached to the lower surface of a transparent base sheet, and the base sheet is provided at the upper or the lower surface with a fluorescent layer in the location above the movable contact point. Since, in the make-up, light can be made available for illumination in many colors other than that generated from a light emitting device, a movable contact element, as well as a switch formed using the contact element, that offers various illuminating modes can be implemented in a simple structure.
