| An electrical contact material includes a surface layer formed of a noble metal or an alloy containing the noble metal as a major constituent. An organic film having heat resistance is formed on a surface of the surface layer, and the organic film is formed of an organic compound having an ether bonding group. Accordingly, the electrical contact material has good corrosion resistance and sliding resistance. | ||||||

| A device 20 includes a substrate 22 coupled with a substrate 24 such that a volume 32 is formed between the substrates 22, 24. Contact posts 48, 50 on the substrate 22 and a cantilever beam structure 36 on the substrate 24 are located within the volume 32. The cantilever beam structure has a conductive trace 38 that is selectively contactable with the contact posts 48, 50 to yield a microelectromechanical (MEMS) switch within the volume 32. Fabrication methodology for making the contact posts 48, 50 entails forming post protrusions 68, 70 on the substrate 22 and shaping post protrusions 68, 70 so that they acquire a rounded shape. Input and output signal lines 42, 44 are constructed such that respective portions of input and output signal lines 42, 44 overly corresponding post protrusions 68, 70 and take on the shape of post protrusions 68, 70. | ||||||

| A switch provided with a fixed contact and a movable contact coming into contact with each other and separating from each other. The surface of at least one of the fixed contact and the movable contact is provided with a plurality of recesses whose edges are overlapped with each other, and also provided with a plurality of projections.

| 206 | Sliding contact and method for producing the same | US10486099 | 2004-02-09 | US20040205965A1 | 2004-10-21 | Mitsuyoshi Sayama; Kenitiro Tani; Hirohito Suzuki |
| The object is to provide a method of manufacturing a sliding contact which has a high yield of manufacturing sliding contacts and can positively make smooth the tip portion surface of a finger of a brush of a sliding contact. According to the invention, in a method of manufacturing a sliding contact having a metal brush, the tip portion of a finger 12anull of a sliding contact piece 10null is melted and thereafter the tip portion is solidified in a gas, whereby the surface of the tip portion is made smooth. For example, when a sliding contact is manufactured by blanking a metal sheet material, the tip portion of the finger 12anull of the brush 12null of the sliding contact piece 10null which is obtained by blanking is irradiated with a laser beam, whereby the tip portion is heated and melted. Then, a sharp portion and a burr which exist before melting disappear. When the tip portion of the finger 12anull is solidified in a gas after melting, a sliding contact having a brush provided with a finger whose tip portion surface is a smooth curved surface is manufactured. | ||||||
| 207 | Electrical contact | US447386 | 1995-05-23 | US5639271A | 1997-06-17 | William H. Balme |
| An electrical contact has a general flat sheet metal support with a pad portion that is twisted (e.g., by about 90 degrees) out of the plane of the metal support, and a contact body attached to the pad portion. The contact may be made by welding a contact body on a pad portion of the contact support while the contact support is essentially in its original flat state; and using one progressive stamping die to isolate the pad portion, form a twist, and stamp out the contact, so that the pad portion is in a plane that is generally perpendicular to the plane of the contact support. | ||||||

| This invention concerns a method of making electrical contact buttons comprising the steps of presenting a strip of clad metal having a width narrower than the diameter of a finished contact electrical contact button and having a thickness greater than the thickness of the finished electrical contact button to a coining operation where the strip is successively pressed between a coining punch and a coining die to successively plastically deform uniformly spaced apart portions of the strip into the configuration of the electrical contact button. Tranverse ribs are then formed in the spaces between contact buttons in order to prevent forward flow of the metal during plastic deformation thereof. The electrical contacts are then punched out of the strip. | ||||||

| 216 | Method of producing a multicontact spring | US88631 | 1979-10-26 | US4345372A | 1982-08-24 | Kenji Sekigawa; Takeshi Sato; Mikio Motizuki |
| A multicontact spring having a number of contacts per unit width is produced by press working. A metal tape for a spring is blanked to form a blank. The blank is pressed to make linear dents and, then, cutting of each one of the linear dents is performed. The blank having the cut parts is deformed to form it into a suitable shape for contact points. The thus produced multicontact spring has cut and deformed parts, i.e. contacts, having no free ends. Thereafter, if desired, one end part of the blank is cut to form another type multicontact spring having contacts which have free ends, respectively. | ||||||

Then, the I-shaped contact materials are perforated across the middle thereof in conjuction with the adjoining portions of the electroconductive material so as to divide each contact material into two contacts separated by a contact gap formed therebetween. A leaf spring fitted at one end thereof with a movable contact intended for insertion into said contact gap is held in position, though not in an immobilized state, with the other end thereof simply inserted around the stem of a spring support. Terminals which are retained in their fixed relative position by means of a webbing interconnecting them are fastened with adhesive agent to a plastic case.
