| PURPOSE: To easily separate a keyboard from a circuit substrate for sealing a key, preventing liquid from flowing into the circuit substrate, completely cleaning and sterilizing the key. CONSTITUTION: Plural flexible elastic domes 32 corresponding to the keys 16 and semitransparent thin films 20 which are arranged between a panel and a substrate 24 and which form liquid resistant seals between the panel and the substrate 24 are provided. Thus, liquid is prevented from flowing into the substrate 24 even if it drops from the key 16. Conductive surfaces 76 which correspond to the respective flexible elastic domes 32 and are arranged on sides facing to the substrate 24 of the semitransparent thin film 20 are provided. When the key 16 is depressed, the corresponding dome 32 is deformed and the conductive face 76 belonging to the corresponding dome 32 is pressed to one corresponding contact land 78. Thus, an electric operation corresponding to a key 16 operation can securely be realized. COPYRIGHT: (C)1995,JPO | ||||||

| PURPOSE: To lessen the number of component items so as to simplify assembling by moving the curved face of one part of a dome portion downward so as to e inserted, and bringing two circuit patterns into contact with each other so as to form an electric circuit when operation force is applied to the dome portion. CONSTITUTION: As seeing a key display provided on a cover sheet 130, a user places a finger on a predetermined key station, pushes down a key, brings circuit patterns 114, 124 into contact with each other so as to form a circuit to generate an electric signal from a keyboard. When operation force is applied to a specific key through the cover sheet 130, the operation force is transferred to a dome portion 126 via a dome-like actuator 128, the dome portion 126 is moved downward so that the circuit pattern 124 is brought into contact with the circuit pattern 114 to form an electric circuit. In this downward movement, a curved face is inverted at one part of the dome 126 as shown in a dotted line so that a snap action is caused, and such pleasant feedback as the establishment of the electric contact of the patterns 114, 124 is felt.

| 87 | 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 to-be-depressed member includes an elastic dome. A sectional shape of the dome orthogonal to an axis line (X2) of the dome is line-symmetric about a symmetry axis (Ax). The dome has a three-dimensional shape that is symmetric with respect to a virtual plane (Sx) containing the symmetry axis and the axis line. During a swinging movement responsive to a depressing operation, an opposed surface of an opposed member relatively approaches and contacts a distal end of the dome to deform the dome so as to generate a reactive force. As for an angle defined between the axis line of the dome and a normal line (X1) of the opposed surface, the angle (θ0) in an initial state falls in a range from a first angle variation amount from the initial state to a first-contact state to a second angle variation amount from the initial state to a depression-completed state. | ||||||
