摘要： A key device for a computer keyboard has a rigid printed circuit board, a flexible printed circuit board, and a key structure. The rigid printed circuit board has two adjacent but unconnected conductive ends electrically connected to two wires respectively. The flexible printed circuit board, fixed over the rigid printed circuit board, has a conductive segment installed above the two conductive ends, and an isolation layer installed around the conductive segment to form a gap between the conductive segment and the two conductive ends. The key structure is moveably fixed on the flexible printed circuit board in an up and down manner. When the key structure is pushed downward, the bottom of the key structure will touch the conductive segment of the flexible printed circuit board, and the conductive segment will touch the two conductive ends of the rigid printed circuit board to electrically connect the two conductive ends and the two wires.

摘要： Keyboard switch assembly comprises first and second insulating supports having opposed spaced-apart first and second surfaces. The first support is a flexible film and has circuit conductors on the first surface thereof which extend to switch sites. Each switch site has a pair of spaced-apart switch electrodes. The second support is a rigid one piece molding having a bezel which surrounds a sunken surface. The first surface of the first support is disposed against the sunken surface. The sunken surface has recesses therein at the switch sites and the floors of the recesses are covered with conductive material such as conductive ink. The floors of the recesses are the second surface. A switch at a switch site is closed by pressing on the first support so that spaced-apart electrodes both contact the conductive material on the floor of the associated recess in the sunken surface of the second support.

摘要： Die Tastatur weist zwischen mehreren (getrennt) gezeigten) Folien oder Platten (l,2,3,4) angeordnete Dehnungsmessstreifen (5) auf. Bei Druck auf den Tastenbereich oberhalb eines Dehnungsmessstreifens ändert dieser seinen elektrischen Widerstand. Die Widerstandsänderung ist auswertbar um ein der Taste der Tastatur zugeordnetes Nutzsignal zu schalten. Die Tastatur kann sehr flach ausgestaltet werden, kann schon bei geringem Fingerdruck ansprechen und ist einfach herstellbar.

摘要： A membrane switch panel has a printed circuit base board (20) carrying bare copper electrical circuitry (26) and contacts (26 & 28). A flexible, non-elastomer, laminar membrane (22) overlays the board (20) and also carries a bare-copper contact (24). An electrically insulating spacer (3) is provided between the board (20) and the membrane, but is provided with an opening to allow the contact (24) upon local depression of the membrane to bridge the contacts (26 & 28) in the base board (20). The membrane (22) is adhesively sealed to the base board (20) enclosing an atmosphere of limited tarnishing ability for the contacts (20, 26 & 28) to maintain a low contact resistance and allow non-precious metals to be used for contacts.

摘要： A low profile switch or keypad has one or more touch pads (14) formed integrally with and raised from a surrounding membrane or key mat (15) of elastomeric material by a wall (30) of resiliently deformable material of thickness and angle relative to the mat (15) so that the wall (30) can flex under finger pressure on the or each pad (14) without deflecting the surrounding membrane. The underside of each pad (14) is formed with a convex contact pad (29) dimensioned in relation to the pad diameter and travel and the length of wall (30) so that the pad (29) makes surface to surface contact with conductors (12), (13) of an underlying circuit board (10). The mat (15) is held in tension to the board (10) by a peripheral lip (16) into which the board (10) fits. The keyboard uses only two interfitting parts and needs no bezel but provides a tactile response to key depression.

摘要： A keyboard switch assembly including a printed circuit board having four switch terminals on one side of the board, three of the terminals being arranged in a triangle and the fourth disposed within the triangle. Conductors on the one side of the board are respectively joined to the interior terminal and at least one of the three terminals. A conductive, generally triangular, snap-acting dome switch member is provided having arcuate apices, projections being respectively formed from the apices and respectively engaging the three terminals thereby spacing the periphery of the switch element from the one surface of the printed circuit board and the conductors thereon, at least the conductor connected to the interior terminal extending under the dome. The switch element has a fourth protection formed from the interior of the dome adjacent the center thereof which is in registry with the interior terminal and engages that terminal when the dome is deflected thereby completing an electrical circuit between the three terminals and the interior terminal. A layer of insulating material covers the conductors exclusive of the terminals. A sheet of insulating material covers the insulating layer and has an opening therein which receives and locates the switch member. Another sheet of insulating material covers the first sheet and the switch member. A plate covers the second insulating sheet and has an opening therein which receives a push button in registry with the switch element, depression of the push button actuating the dome of the switch member to a nonovercenter, deflected position in which the interior projection on the dome engages the interior switch terminal.
