    Abstract: A printed circuit board (1) comprising a dielectric film substrate (2) and a plurality of circuit patterns for a capacitor switch formed on said dielectric film substrate at a certain space from each other. Each of the circuit patterns comprisies a switch electrode pair (5A, 5B) formed on one surface of the dielectric film substrate, a first fixed electrode connected to one of the switch electrode pair, a first lead pattern connected to the other of the switch electrode pair, a second fixed electrode formed on the other surface of the dielectric film substrate in such a manner as to be opposed to the first fixed electrode through the dielectric film substrate, said first and second fixed electrodes forming a fixed electrode pair, and a second lead pattern connected to the second fixed electrode. A plurality of the fixed electrode pairs are arranged at an enlarged space larger than the certain space defined between the circuit patterns, and the density of the first and second lead patterns disposed in the enlarged space is reduced.

    Abstract: A pressure transducer device particularly useful in an electronic musical instrument includes a flexible base folded to define upper and lower flexible base portions, a donut-shaped first spacer between the upper and lower base portions and a resiliently deformable diaphragm attached about its periphery to the upper flexible base portion with a second donut-shaped spacer therebetween. A center region of the diaphragm laterally spaced from the second spacer is adhesively attached to a central region of the upper flexible base portion so that the upper flexible base portion moves inwardly and outwardly in response to the movement of the diaphragm. A pair of conductors are disposed on the folded flexible base member to face one another. A pressure responsive composition disposed over the conductors provides a contact resistance across the pair of conductors which varies inversely with the amount of pressure force exerted against the diaphragm. The upper flexible base portion may be attached between the first and second spacers about its entire periphery or at a small hinge region with the upper base portion being a flap movable about the hinge region in the region surrounded by the first spacer.

    Abstract: Different from conventional push-button switches with which an electric circuit is closed and opened as the button top is pushed with a finger tip and as the finger tip is withdrawn from the button top, respectively, the inventive push-button switch operates in a unique manner that the electric circuit is opened already as the pushing force by the finger tip is still on the way of increasing. The inventive push-button switches utilize the delicate snap back action taking place as the strain in the snap spring portion in the diaphragm covering of the switch exceeds a certain critical point so as to spontaneously pull apart the movable contact member on the inward surface of the covering from the fixed contact points on the base plate while the button top is still under pushing with a finger tip. The inventive push-button switch is advantageous because of the absence of the transient disturbances in the circuit such as chattering and bouncing.

    Abstract: An economical yet versatile dual spring actuator switch assembly providing an excellent tactile impression includes a planar switch closure assembly having domed protrusions extending from a surface thereof to provide switch closure when depressed and a switch actuator assembly. The easily assembled switch actuator assembly includes a cover plate with a guiding, key receiving plate aperture disposed therein opposite each protrusion, a plurality of keys, each key having a central key aperture, and a guide post within the central key aperture and being slideably received by a different plate aperture, a plurality of followers, each disposed adjacent a different protrusion and having a central aperture slideably receiving a guide post in guiding, mating relationship, a plurality of first springs, each maintaining a repulsive force between a different key and the surface, and a plurality of second springs, each coupling a different key to a follower to communicate a switch closure force to a protrusion upon depression of a key. The double spring arrangement permits independent selection of key and protrusion actuation forces and buffers each protrusion from its associated key for longer switch lifetime.

    Abstract: The disclosure relates generally to key assemblies employed in electrical switch operating keyboard devices and more particularly to the improved assembly of parts forming an individual depressible key on such a keyboard. Each key assembly is comprised of parts cooperatively interfitting to provide both audio and tactile feedback for the keyboard as well as a bifurcated electrical contact provision. Included in each key assembly is a spring having a buckling beam member with two end supports that will resist a key depression, a hermetic rubber pad that will also resist key depression and a pair of spring straddling members depending from the key assembly for conveying forces employed to depress the key to the switch associated with the assembly to effect closure of the same as well as for substantially reducing if not eliminating a detrimental contact bounce encountered in the operation of such assemblies. The force transmitting pair of depending members cooperate with the straddle spring to provide a rocker or teetering motion in conjunction with the desired bifurcated action for assuring closure of the contacts.
