| 61 | Keyboard switch assembly having raised contacts supported by helicline legs on a common conductive sheet | US508482 | 1974-09-23 | US3979568A | 1976-09-07 | Wendell C. Johnson |
| A switching device having a movable contact that is an integral part of a metallic support substrate and is supported above the support substrate by a plurality of spring-like support legs that are also an integral part of the support substrate. The support legs extend radially outward from the movable contact and contact the substrate and the movable contact at equally spaced points. The movable contact is aligned with either a stationary contact or another movable contact and a stationary contact to provide either single or multiple switching. The switching device can be used for contact switching or capacitive switching. A plurality of the switching devices can be formed on the support substrate making the switching device particularly well suited for use in a keyboard. A portion of each support leg may be thinned to provide a negative force-displacement characteristic which provides a good tactile feedback signal indicating switching.One or more of the switching devices are produced by forming one or more groups of curved, unconnected, radially extending slots in a metallic substrate, deforming the legs defined by the slots past their elastic limit, and then, if desired, precipitation hardening the completed structure. To assure movement of the central area of the movable contact past the plane of the support substrate, a portion of each of the legs is thinned prior to the legs being plastically deformed. | ||||||
| 62 | Keyboard switch assembly having movable contact, and supporting helicline type legs disposed co-planar to common conductive sheet | US508480 | 1974-09-23 | US3968336A | 1976-07-06 | Wendell C. Johnson |
| A switching device having a movable contact element characterized by a set of unconnected, curved slots radiating outward from a central key area and equally spaced around the central key area. The radially extending unconnected, curved slots may be sections of a spiral, at least some of which sections overlap each other. Adjustment of the spring rate of the movable contact element is accomplished by adjusting the length of the slots or by regulating the distance of the inner terminus of the slots from a central point of the central key area. The movable contact element either contacts a second contact element for contact switching or approaches the second contact element for capacitive switching.A plurality of the switching elements can be formed in a planar array on a continuous metallic substrate to provide a keyboard. The movable switching elements can be formed on the metallized areas of a printed circuit board. | ||||||
| 63 | High speed serial scan and read-out of keyboards | US3745536D | 1971-03-01 | US3745536A | 1973-07-10 | KLEHM W |
| Relates generally to the production of electrical signals from a keyboard, each key of which is individually operatively associated with a switching device whose activation to electrical conductive condition is controlled by the displacement of the key. These switches are hermetically sealed from the atmosphere and are electrically scanned in succession at relatively high speeds and at a repetitious rate such that several scanning cycles occur during the normal activation of a selected key. The keyboard mechanism also includes a shift register having one more bit position than the number of switch devices and into which a bit is introduced into the ''''one'''' position at the instant the scan encounters a closed switch of the keyboard. This bit is then shifted through the register in timed relation to the scan of the remaining key switches and unloaded into the last bit position of the register. A detector senses the presence of a bit in both the ''''one'''' position and the last position of the shift register and upon detection of a bit solely in the one position it delivers a signal indicative of the character represented by the actuated key and upon detecting bits in the two extreme positions of the shift register it nullifies the delivery of such a signal.

| 70 | Mechanical keyboard with membrane switch arrray | EP84305716 | 1984-08-22 | EP0157035A3 | 1987-03-18 | Ellson, Allan |
A key actuated membrane switch comprises a key operated switch actuating member 101 in the form of a key module and a membrane switch panel 111. The switch panel consists essentially of three membranes (112, 113, 114), one on top of the other, sealed together with adhesives. The upper and the bottom membranes (112, 113) are each continuous and each has at least one contact (115) and a respective conductor formed on its interior surface. The middle membrane (114) has at least one aperture (117) which defines a switch cell. The two contacts (115) are coaxially aligned with the aperture so that pressure on the upper membrane (112) along the axis of the aperture, causes the two contacts to come together and make a circuit. The membrane package is mounted, prefer- ebly by an adhesive, on a rigid base 120. Pressure is selectively applied to the upper membrane by means of the key operated switch actuating member (101) via the agency of a cantilevered single-arm spring (104) which acts to apply leverage on the upper membrane (112) when the actuating member (101) is operated. The spring has a first portion which extends from the supported end of the spring in a plane parallel to the plane of the upper membrane to the vertical axis of the said contacts, and a (Continuation next page) second portion which extends upwards, at an angle, to the actuating plunger (108) of the actuating member. When the latter is actuated the spring (104) is flexed downwards and hinges during the first part of its movement about its supported end, thereby displacing the bend or "knee" (107) intermediate the two portions of the spring arm. The knee therefore applies pressure, with mechanical advantage, on the upper membrane (112). When the contacts come together. no further displacement of the knee (107) is possible and any further displacement of the free end of the spring causes flexing to take place at the knee and in the second portion of the spring. In a preferred arrangement the said spring (104) is supported by means of a dog-leg portion (105) which is entered into a vertical slot (106) provided on the base of the actuating member (101). The slot contains facing ribs (121, 122) which cause the dog-leg portion to flex as it is pushed into the slot. This flexing results in a frictional force being exerted by the dog-leg portion on the ribs which serves to prevent the spring from falling out of the slot. Any tendency for this to happen is also counteracted by the leverage exerted by the spring (104) as it attempts to rock about its "knee" during overtravel of the spring. Also in the preferred arrangement the actuating member (101) is fastened onto the upper membrane (112) by an adhesive. The above arrangement is particularly intended as a keyboard switch. |
