| 201 | Electrical contact having a particulate surface | US349042 | 1994-12-02 | US5527591A | 1996-06-18 | David R. Crotzer; Gregory E. Dean |
| The present invention comprises an electrical contact having solid homogenous conductive particles on the contact surface. The particles are of greater hardness than that of the contact material to deform the contact material and cause breakage or fracture of the oxide or other contaminating layer, or to penetrate the contaminating layer. The particles are applied to the contact surface by a technique which results in the particles being intimately bonded to the contact surface, usually as a layer of particles. A preferable technique for such particle application is hypervelocity oxygen fuel spraying (HVOF) or plasma spraying, by which the particles are embedded on the contact surfaces to provide a substantially permanent interparticle bond between the applied particles and the contact material. | ||||||
| 202 | Method for fabricating a contact assembly of a magnetic switch | US167954 | 1993-12-16 | US5467632A | 1995-11-21 | Mitsuhiro Kogure; Shinichi Nagashima; Kazuhisa Wakabayashi; Shigeyuki Enkaku; Hitoshi Shimayama; Minoru Kimura; Shuji Shimoyama; Tsugio Yokoo |
| The capability of heat dissipation from the contact surface of a magnetic switch for a starter motor is improved without increasing the fabrication cost. A punch 28 having a plurality of square projections arranged in two mutually perpendicular directions at the pitch of P is applied to the surface of a plate member 27 to form a first group of punched recesses 29a. The pitch P is twice the length of a side of each punched recess 29a. Then, the punch 28 is shifted with respect to the first group of punched recesses 29 by P/2 in both the vertical and horizontal directions before forming a second group of punched recesses 29b. The punched recesses 29a and 29b define projections 26 in the parts which are not occupied by these recesses generally in the pattern of a checker board. Because the projections 26 are separated from each other, and can effectively dissipate heat therefrom, the increase in the contact resistance due to heat generation can be prevented, and the efficiency of the starter motor can be increased by using a punching process which is both simple and economical. | ||||||
| 203 | Micromachining methods for making micromechanical moving structures including multiple contact switching system | US286722 | 1994-08-05 | US5454904A | 1995-10-03 | Mario Ghezzo; Richard J. Saia; Bharat S. Bagepalli; Imdad Imam; Dennis L. Polla |
| Micromachining methods for fabricating micromechanical structures which include plunger elements free to reciprocate within cavities are fabricated using processing steps in common with those employed in high density interconnect (HDI) technology for multi-chip module packaging. A polymer, such as a polyimide, is utilized as a micromachinable material. In one embodiment, cavities are formed in the polymer material by laser ablation, employing a sacrificial layer as a mask. Electroplated copper may be employed as a sacrificial release layer. One particular structure is a micromechanical electric switch including an array of individual switch contacts actuatable in common. | ||||||
| 204 | Interconnecting device between contacts in electric switches and the like | US93469 | 1993-07-19 | US5391847A | 1995-02-21 | Cesare Gallone |
| In an electric switch, a movable contact element (6, 106) is linked to a first fixed contact (3, 103) by an end portion (14, 114) having a sharp-edge outline and housed in a seating having a rounded outline. The movable contact element (6, 106) has an interconnecting portion (9, 109) provided with a frusto-conical projection to be engaged in a coupling opening (18, 118) having rounded edges and formed in a second fixed contact (4, 114), so as to establish an electric continuity between the first and second fixed contacts when the movable contact element (6, 106) is brought to a closed condition. A first silver insert (16, 116) is joined on the interconnecting portion (9, 109), which insert has a larger volume than a second silver insert possibly joined on the edges of the coupling opening (18, 118). A protection cap (20, 120) arranged on the interconnecting portion (9, 109) receives the metal fragments projected from the contact area between said interconnecting portion and the second fixed contact (4, 104) following breaking and restoring of an electric continuity. | ||||||

| 207 | Method of making electrical contact | US675849 | 1991-03-27 | US5072521A | 1991-12-17 | Noboru Sasaki; Masayuki Ueyama |

| 208 | Change of state contact material for electric circuit interrupters | US763581 | 1985-08-08 | US4607148A | 1986-08-19 | Edward K. Howell; Ira B. Goldman |
| A change of state circuit breaker contact material provides a low contact resistance at a low closing force by reducing current density through a pair of circuit breaker contacts. The use of a meltable metal alloy within the contact structure forces the current through a wider area of conduction whenever the temperature increases to melt correspondingly larger quantities of the metal alloy. The reduced contact hardness results in a substantial decrease in the force required to hold the contacts together, thereby allowing the contacts to open more quickly. | ||||||

| 211 | Method of making keyboard assemblies | US662037 | 1976-02-27 | US4042439A | 1977-08-16 | 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. | ||||||

| 219 | Precious metal switch contact component and its preparation method | US14896403 | 2014-09-15 | US10026564B2 | 2018-07-17 | Huisheng Han; Hongmei Zhang; Yang Ding; Zhihong Dong; Cheng Huang |
| This invention discloses a preparation method for precious metal switching contact components by means of plating masking, plating and etching processes. The plating masking process is performed by using a plating mask ink with or without a photo exposure machine. Plating of precious metals is performed by electroless plating or electro plating methods. Etching is carried out with etching solutions containing weak organic acids, weak inorganic acids or acidic buffering agents. Improvement of the etched surface gloss and prevention of the side etching are realized with the sulfur-contained compounds. The dust- and oil stain-resistances of the switch contacts are improved by increasing the etching depth. The switch contacts made by this invention are featured with the advantages of good reliability, good resistance to dust and oil stain, short contact bounce time, long service life, low cost of raw materials and so on. | ||||||
