| A switch device includes a contact member and a plunger that removably connects to the contact member. The contact member creates a first audible feedback sound in response to being placed in a first electrical state. Additionally, a switch device includes a compressible contact member including at least one removable electrical contact portion, and a movable member that removably connects to a center portion of the compressible contact member. The compressible contact member creates a first audible feedback sound in response to being placed in a compressed state by the moveable member and creates a second audible feedback sound in response to being uncompressed. | ||||||
| 62 | MULTI-FUNCTION SWITCH STRUCTURE | US12716851 | 2010-03-03 | US20100224473A1 | 2010-09-09 | Peter Andrew Jeffery |
| A switch has multiple movable contacts, such as snap domes, positioned in a stacked relationship with each other. The stacked relationship may be such that the apexes of each dome point in the same orientation, or the apexes may be in an opposite orientation so that they point toward or away from each other. When the switch is initially depressed, one of the contacts forms a first electrical connection. When the switch is further depressed, a second one of the contacts forms a second electrical connection. Alternatively, multiple moveable contacts are positioned on the same plane under a single bubble of a carrier sheet. Multiple actuating elements may depress each of the domes. Adjacent domes may share common conductive traces. | ||||||

| 64 | Dome switch with integral actuator | US12142333 | 2008-06-19 | US07687734B2 | 2010-03-30 | Douglas Weber |
| A dome switch structure that includes an actuator integrally formed with a dome is disclosed. Advantageously, the actuator can be formed so as to be positioned over and properly aligned with the dome. In one embodiment, the dome switch structure is used by an electronic device to provide user input. When the actuator is pressed by a user, the actuator depresses the dome and induces a switching action. In one embodiment, the dome switch structures can be manufactured (i.e., machined) as a unitary structure. Consequently, since actuators and domes can be formed together, the dome switch structures yield not only consistent accurate alignment but also simplified assembly of dome switches. Given the accurate alignment of an actuator to a corresponding dome, dome switches formed from the dome switch structures can have consistent and reliable tactile feel to users, which thereby provides reliable usage by users. | ||||||

| Described is a keypad and its method of manufacture. In one embodiment, a keypad is provided that includes a substrate having a plurality of donut-shaped recesses located at each site of a button for inputting user information, a plurality of cushions each filled with an incompressible fluid (e.g., water), a flex circuit layer, a plurality of metal membranes and an over-molded thermoplastic elastomer layer. During the over-molding of the thermoplastic elastomer layer, the plurality of cushions filled with an incompressible fluid prevents collapse of the space between the flex circuit layer and the plurality of metal membranes. After the layers of the keypad are assembled, the incompressible fluid is removed which leaves a space between the flex circuit layer and the plurality of metal membranes. | ||||||

| Electronic apparatus that can be disposed in a small space and allows multidirectional input without impairment of a click feeling. A cross key including a plurality of pins is elastically held by an operating member holding mat including a plurality of holes into which the respective pins are insertable. An analog switch overlapped on the operating member holding mat outputs a signal when one of the pins comes into direct contact with the analog switch in response to operation of the cross key. A metallic dome sheet overlapped on the analog switch outputs a signal when one of the pins comes into contact with the metallic dome sheet via the analog switch in response to operation of the cross key. The metallic dome sheet outputs a signal after the analog switch outputs a signal. | ||||||

| A keyboard system for an electronic pocket calculator or the like comprises a substrate board having a generally flat surface with a network of circuit paths thereon. The board is provided with switch contacts at a plurality of switching stations and terminals at a margin of the board for electrical interconnection to other electronic components (e.g., to the solid state logic components or the like on the motherboard of the calculator). Conductor paths and the network of circuit paths interconnect the contacts and the terminals. A dielectric layer is disposed on the substrate leaving the portions of the network of circuit paths exposed. A plurality of spaced electrically conductive inner contact portions are disposed on the substrate in electrical communication with certain ones of the exposed circuit paths and a plurality of outer contact portions are disposed on the top of the dielectric layer, an outer contact portion adjacent each inner contact portion, the top surface of the outer contact portion spaced from the substrate a greater distance than the top surface of the inner contact position is spaced from the substrate. A switch actuating electrically conductive disc is placed over each outer contact portion and is resiliently deformable between an initial position in which its outer margin is in contact with the outer contact portion and in which it is clear of the inner contact portion and an actuated position in which the outer margin of the disc remains in contact with the outer contact portion and in which one point of the disc is in contact with the inner contact portion thereby to complete a circuit between the inner and outer contact portions. A sheet of flexible insulative material is adhesively bonded to the keyboard and to the outer faces of the discs for securing the discs in position relative to their respective contact portions for permitting the discs to be deformed to their actuated positions and for sealing the discs to the board. | ||||||

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.
