    Abstract: A printed circuit board comprising a dielectric film substrate 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 comprises a switch electrode pair 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: The invention relates to a keyboard having sudden trip tactile effect keys.Such a keyboard comprises a flexible and conducting foil stamped with protuberances, each of them having a central upper flat part, with an area less than the area of the base of the protuberance, and a lateral part, connecting the central part to the base of the protuberance, and comprising or not substantially flat counter-shapes, which is deformed and touches a contact zone of a printed circuit placed therebelow, when a pressure is exerted on the central part.These keyboards find applications in remote-control boxes or else in pocket calculating machines.

    Abstract: The disclosure relates generally to key assemblies employed in electrical switch operating keyboard devices and more particularly to the assembly of parts forming an individual depressible key of such a keyboard. Each key assembly is composed of parts cooperatively interfitting to provide both a low profile for the keyboard as well as a bifurcated electrical contact provision. Included in each key assembly is a pair of coiled springs of different diameters which are coaxially and overlappingly related to one another. The smaller diameter spring of the pair is a double rate spring and as such is formed with two longitudinal sections of different helical pitches 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 spring member acts through a terminal member shaped to provide a teetering motion in conjunction with the desired bifurcated action for assuring closure of the contacts. The assembly is composed of parts formed mainly of plastic material molded to shape and as such provides a durable, light-weight, and low cost structure.

    Abstract: Some embodiments of the present disclosure relate to a relay capable of preventing a chattering phenomenon, and capable of solving an unbalanced contact state occurring when contacts come in contact with each other.The relay may include: a stationary contact having a first stationary contact and a second stationary contact; a movable contact moveable to a first position to contact the first stationary contact, and a second position to be separated from the first stationary contact; a conductive connector configured to always electrically connect the movable contact with the second stationary contact; and a driving mechanism configured to provide a driving force to the movable contact such that the movable contact is moveable to the first position or the second position.

    Abstract: An apparatus and method for de-bouncing keypad inputs is disclosed including interrupting a processor upon detecting a key press, reading input signals from the key pad to determine an initial port value and starting a timer. A keypad interrupt is disabled and processing resumes until expiration of the timer. The timer interrupts the processor and the input signals are read a second time and combined with the initial port value to determine a key identifier. The timer is started again and processing resumes. Upon expiration of the timer the processor checks for key release. If release is not detected, the timer is again started. If release occurs, the timer is disabled and the keypad interrupt is enabled.

    Abstract: Disclosed is a pushbutton-type switch such as used on the keyboard of a small-size electronic computer. The switch includes a main member carrying a movable contact and one or more projections or posts of lesser height than the movable contact. Upon application of finger pressure to the main member, the movable contact is brought into uniform contact with a fixed contact therebelow without chattering, by virtue of the supporting action of the posts.
