| 11 | Flexible diaphragm keypad and method of manufacture | US683892 | 1984-12-20 | US4609791A | 1986-09-02 | Jean-Pierre Abbat |
| A keypad is formed of a set of transparent buttons slidably located within apertures of a grid. The grid has sidewalls for engagement with the base of a printed circuit board. Switch assemblies are provided by conductive elastomeric domes formed of a single sheet of elastomeric material disposed between the printed circuit board and the buttons. Integrally formed within a concave side of each dome is a contact region driven by a displacement of a button towards the printed cirucit board. An insulating layer above strip conductors of the circuit board is perforated at sites of the switches to allow the contact region to touch the exposed portions of the conductors to complete an electrical circuit. A dome deforms with springiness which urges the dome back to its original shape upon release of a button by a user of the keypad. Manufacture of the keypad is facilitated by construction of a set of the butons on a webbing which maintains alignment of the buttons as they are secured to the respective domes. The webbing is later removed to permit insertion of the buttons into apertures of the grid. | ||||||
| 12 | Double-domed elastomeric keyboard element | US296628 | 1981-08-27 | US4378478A | 1983-03-29 | Reinhard Deeg |
| A double-domed elastomeric keyboard element is disclosed in which a solid contact disc is connected to the junction of the domes of the keyboard element housing. The inner dome is provided on its inside with a downwardly extending projection which engages the contact disc when the keyboard element is depressed to press the disc against a pair of conductors on a printed circuit board below the element. Because of the non-positive connection between the key plunger and the conductors, the contact pressure is almost equal to the operating force. | ||||||

| A keyboard structure includes a frame, a button, a first circuit unit and a second circuit unit. The frame includes at least a through hole. The button is disposed at the through hole and magnetically connected with the frame. The first circuit unit includes a first electrical contact point disposed corresponding to the button. The second circuit unit includes a second electrical contact point disposed corresponding to the first electrical contact point. When the button is pressed, the button and the frame are separated, and the first electrical contact point contacts with the second electrical contact point. | ||||||
| 14 | High voltage resisting keyboard | US10857967 | 2004-06-02 | US20050271442A1 | 2005-12-08 | David Ho; Tony Tsai; Tao Xia; Zhi-Zhong Hong |
| The present invention discloses a high voltage resisting keyboard comprising at least one press key on a casing, a circuit board inside the casing, and a metal dome between the press keys and the circuit board inside the casing, wherein the edge of the metal hemisphere of the metal dome is directly connected to an end of an electrode of the circuit board, and the other end of the electrode is connected to an end of a resistor. Thus, when the edge of the metal hemisphere receives the high voltage current, the keyboard is protected by the resistor to avoid the high voltage current from being sent directly to another end of the resistor that is connected to another electronic component to achieve the purpose of protecting another electronic component. | ||||||
| 15 | Membrane switch and pressure sensitive sensor | US10159119 | 2002-06-03 | US20030000821A1 | 2003-01-02 | Katsuhiko Takahashi; Takayuki Imai; Toshio Ochiai; Toshifumi Nakajima; Koji Ito; Kazuya Tanaka |
| A pressure sensitive sensor is composed of a pair of upper and lower electrodes sheets 1 and 2 disposed oppositely, a spacer 3 interposed between both of the sheets 1 and 2, and adhesives 4 and 5 between these electrode sheets 1 and 2 and spacer 3. In the spacer 3, a hole 31 is formed in a position of a contact portion 6. A diameter of this hole 31, convex portions 13 and a pressure sensitive electrode 22 are set in such a positional relationship that a peripheral portion of the hole 31 is overlapped between the convex portions 13 and the pressure sensitive electrode 22. Then, the adhesives 4 and 5 open more largely than the diameter of the hole 31 of the spacer 3 so as to be removed from the peripheral portion of the hole 31 on both surfaces of the spacer 3. | ||||||
| 16 | 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. | ||||||
| 17 | MULTI-POLE DOME SWITCH | US16006790 | 2018-06-12 | US20180358191A1 | 2018-12-13 | Trent Zimmer |
| Implementations of a multi-pole dome switch configured to simultaneously, or nearly simultaneously, close or open two separate circuits are provided. In some implementations, a multi-pole dome switch may comprise a tactile metal dome and a conductive insert that are separated by an insulator. In some implementations, when the dome is depressed, the dome and the conductive insert are configured to simultaneously, or nearly simultaneously, make conductive contact with two traces of a first circuit and two traces of a second circuit, respectively, positioned thereunder on a PCB. In this way, the multi-pole dome switch is able to simultaneously, or nearly simultaneously, close two separate circuits. Succinctly put, in some implementations, the multi-pole dome switch may be configured to act as a double-pole, double-throw switch. | ||||||

| A power relay for a vehicle has a housing and two connecting bolts that are introduced into the housing so as to contact a load current circuit. The power relay further having a coil assembly that is arranged in the housing, the coil assembly contains a magnetic coil and a magnetic armature that is coupled by way of a force-transferring member to a contact bridge that can be moved in a reversible manner between a closed position and an opened position and can be displaced in the housing under the effect of a magnetic field that is generated by the magnetic coil. The contact bridge supports two contact elements that together with the mating contacts of the connecting pin form a first contact pair and a second contact pair. The contact pairs form a three point bearing arrangement in the closed position. | ||||||
