| 41 | Trim switch | US249859 | 1988-09-27 | US4924046A | 1990-05-08 | William A. Howard |
| A trim switch control for aligning a motor on a boat. The switch includes a housing in which a switch body is supported. A bridging member includes side lobes having domed contact engaging portions. In response to user actuation, an actuator surface is brought into engagement with the domed side lobes causing deformation of those lobes into engagement with the contacts. This completes an electrical circuit, resulting in user actuated control of the motor trim. | ||||||

| 43 | Snap-through characteristic keyboard switch | US970505 | 1978-12-18 | US4254309A | 1981-03-03 | Dudley B. Johnson |
| A keyboard switch actuating element having a concave central portion and a lip located at the periphery of the actuating element for providing a snap-through characteristic when the actuating element is disposed even over a smooth surface and the actuating element is depressed. The actuating element is typically disposed over conductors forming switch contacts affixed to the surface of a printing wiring board and closes the circuit between such switch contacts upon depression of the actuating element. The snap-through characteristic results from a reduction of the required force to depress the actuating element as the actuating element approaches its fully depressed state. | ||||||
| 44 | Switching assemblies | US15808 | 1979-02-27 | US4195210A | 1980-03-25 | Walter R. Pounds; Bill D. Dunlap |
| A switching assembly includes an insulative substrate upon which is carried a plurality of conductive paths respective portions of which are selectively bridged upon depression of a resilient conductive contact element. That contact element is generally in the shape of a dome and has a central region of substantially planar conformation from which the remainder of the dome slants integrally downward and outward to a lower marginal rim portion. The dome-shaped element is disposed adjacent to the substrate with at least a portion of its rim portion electrically and physically contacting one of the portions of one of the paths. The central region is generally in registry over another of the portions in another of the paths so as to enable connection between the central region and that other portion upon depression of the central region. | ||||||
| 45 | Pushbutton keyboard system and method of making same | US535468 | 1975-01-10 | US3996427A | 1976-12-07 | Perry W. Kaminski |
| 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.

| 46 | Keyboard switch assemblies having two foot support legs on dome-shaped contact member | US576694 | 1975-05-12 | US3967084A | 1976-06-29 | Walter R. Pounds |
| A keyboard assembly includes an insulative substrate upon which are carried a plurality of conductive paths. Respective portions of the paths are selectively bridged upon depression of a dome-shaped conductive resilient contact element. A pair of space-opposed regions of the dome's marginal portion are deformed downwardly away from its apex so as to constitute a pair of space-opposed feet. The feet have a complex shape which leads to high lifetime of the dome. Preferably, the feet rest on corresponding conductive pads, and the pad pairs for adjacent domes may be differently oriented so as better to accommodate the passage of leads between those domes. Leads on the substrate passing beneath dome edges desirably are depressed into the substrate. Overlying the domes in a completed assembly is a layer of deflectable insulating material that is adhesively affixed to the substrate and to the domes; the latter includes an aperture in registry with each dome but of a diameter smaller than the width of such dome. Advantageously, the adhesively-coated layer also is utilized for the purpose of picking up individual domes from a magazine and transferring them to their assigned positions on the substrate. | ||||||

| 56 | DOME-SHAPED MOVABLE CONTACT PIECE | US14849754 | 2015-09-10 | US20160268066A1 | 2016-09-15 | Kunihito SUGIMOTO |
| In a dome-shaped movable contact piece, the durability of the dome-shaped movable contact piece is improved by removing a tearing force at a bent portion during the reverse deformation of a dome-shaped portion to prevent cracks.The movable contact piece includes an upright outer circumference portion formed in an outer circumference of a trapezoid conductive spring plate and a flat portion. When a dome portion is formed by an arm portion between slits, a position close to the center in relation to a corner portion of the slit is set as a bent line so that the dome portion is formed by the arm portion at the center in relation to the bent line. Accordingly, the dome portion is reversely deformed by using the bent line as a bent position. Thus, it is possible to prevent a tearing force from being applied to the corner portion in a twisted state. | ||||||
