| 143 | Low current switching apparatus having detent structure providing tactile feedback | US700237 | 1991-05-15 | US5130506A | 1992-07-14 | Joseph C. Zuercher; Edward G. Lewis; Michael G. Taranowski; Constance L. Williams |
| Pivotal movement of a switch actuator drives a finger projecting from the actuator against a convexly bowed leaf spring, depressing an intermediate portion of the leaf spring to an unstable concave condition. The leaf spring resists the actuator movement, initially with an increasing force but changing to a decreasing force at a predictable point in actuator movement to provide tactile feedback at an operator affixed to the actuator. The leaf spring is a flat beam. The spring force and point of changeover can be readily and predictably varied during manufacture by selecting springs having different widths, thicknesses or other variable parameters. A modular block holds the spring in the bowed condition and is positioned relative to the actuator finger by a support plate. The actuator finger drives the spring against a conductive rubber block, compressing the block against spaced conductors on a printed circuit to complete the circuit. A plurality of such switches are made in a common package by layering a printed circuit, insulator sheet, conductive rubber sheet with raised bosses, detent support plate and a plurality of detent blocks with bowed springs, between a base and a cover. Back lit illumination is provided by a light pipe trapped against the cover as an additional layer. A microprocessor board, connected to the internal printed circuit, is attached to the switch housing exteriorly of the base. | ||||||

| A push switch includes a central contact member arranged on a contact support member with an annular peripheral contact member surrounding the central contact member. An elastic conductive member such as a belleville spring and the peripheral contact member along their entire outer edge portions are fixedly held within an insulating case in a manner to seal the space around the central contact. In addition, an elastic spring member may be provided in a position covering the elastic conductive member. A plurality of the push switches may easily be manufactured on an assembly line by forming a multiplicity of central contacts, peripheral contacts and conductive members in separate processes and sequentially going through a first and second insert molding processes. | ||||||
| 145 | Magnetically snap actuated contact keyboard apparatus | US693638 | 1985-01-22 | US4689608A | 1987-08-25 | Frank J. Bolda; John P. McKnight; Russell J. Sturm |
| In the preferred embodiment of the invention, the snap actuator is an angled magnetically permeable plate. One leg of the angled plate is attracted to a strip magnet placed on a circuitboard. This particular portion of the plate also has two spring fingers that make contact with spherical or domed contacts on the circuitboard or, in the alternative, have formed dome portions in the end of each finger for contacting flat contacts on the circuitboard so that a wiping action that is resistant to contamination results. The other leg of the angled plate serves as a lever arm to which key button pressure is applied. The angle between the plates or the edge of the strip magnet serves as a fulcrum for pivoting the plate under the influence of key pressure. When key pressure has built up sufficiently, the magnetic attraction is substantially broken and the angled plate is suddenly released, thereby breaking contact with the circuit contacts and allowing the circuit voltage to be sensed. | ||||||
| 146 | Universal keyboard and method of producing same | US190177 | 1980-09-24 | US4359612A | 1982-11-16 | Craig E. Rooney |
| An extremely low cost, high speed, full stroke keyboard is disclosed which provides momentary impulse operation. N-key rollover protection and standard tactile feedback. The keyboard includes a plurality of depressible keys mounted on respective upright synthetic resin flaps designed to collapse upon key depression and engage and move an underlying, resilient, U-shaped shifting member; the member in turn engages and shifts another U-shaped resilient element which supports one or more upstanding encoding posts. When the U-shaped element reaches a cocked position it is disengaged from the shifting member and allowed to snap back toward the original rest position thereof independently of subsequent return movement of the key and shifting member. The snap back motion is sensed and a corresponding key output signal developed. | ||||||

| 148 | 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. | ||||||
| 149 | 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. | ||||||

A key activation system for use in a handheld communication device is provided. The system comprises an activation mechanism associated with a key in the system, a first feedback system and a second feedback system. The activation mechanism is associated with the key activation system and provides a first feedback sense when the activation mechanism has triggered the first activation condition. The second feedback system provides a second feedback sense indicating when the key triggers the second activation condition. In the system, the second feedback system operates independently from the activation mechanism and the first activation condition is triggered before the second activation condition when the activation mechanism is initially engaged. An activation mechanism may be centrally located for a set of keys.

In order to achieve a selectible relationship (key force profile curve) between the displacement of a key top (1) and the force used to depress the key, the position of the key top is detected, and a resistive force corresponding to that position is generated and applied to the key top. Hence, a numeral array for the position data and the force data is stored in a memory (19). To apply hysteresis to a key force profile curve, a RS flip-flop (29) whose output is inverted by the position data may be provided to generate different resistive forces in the key top depressing process and the key top returning process. |
