| A switch includes a first contact and a second contact that are placed along an operating shaft and can reciprocate with respect to each other. An end of the second contact opposite to an end thereof on the side of the first contact is housed in a housing space of a housing box. The pressure in the housing space is increased due to an arc generated when the first contact approaches the second contact. The increased in the pressure causes the second contact to move toward the first contact. | ||||||

| 109 | Contactor Assembly With Arc Steering System | US12341391 | 2008-12-22 | US20090102585A1 | 2009-04-23 | Jeffrey Ramsey Annis; Robert Alfred Duchrow; James Peter Miller; Susan L. Beneke |
| A contactor assembly includes a stationary contact, an arc contact, an arc arrestor, and a magnetic intensifier. The magnetic intensifier is constructed to extend in generally close proximity to one of the stationary contact and the arc contact. During communication of power through the contactor assembly, the magnetic intensifier manipulates a magnetic field associated with current passing through the contactor assembly and increases the magnitude of a magnetic force directed to the arc arrestor. Preferably, the magnetic intensifier is formed integrally with a turnback associated with one of the stationary contact or the arc contact. Such a construction simplifies the manufacture and assembly of the contactor assembly and provides efficient and repeatable arc suppression. | ||||||

| A multiple switch MEMS structure has a higher resistance, higher durability switch arranged in parallel with a lower resistance, less durable switch. By closing the higher resistance, high durability switch before the lower resistance, less durable switch, the lower resistance, less durable switch is protected from voltage transients and arcing which may otherwise damage the lower resistance, less durable switch. By appropriate selection of dimensions and materials, the high resistance, high durability switch may be assured to close first, as well as open first, thereby also protecting the lower resistance, less durable switch from voltage transients upon opening as well as upon closing. | ||||||

| A contact structure for a sliding switch includes a conductive stationary contact disposed on a base and a conductive movable contact for electrically contacting the stationary contact. The movable contact is movable along a path between a non-contact position and a make-contact position with respect to the stationary contact, and at least one of the contacts has a protruding portion that provides an electrical interface for discharge of arcing as the movable contact breaks from the stationary contact. As a result, the invention prevents or substantially reduces degradation in switch performance which might otherwise be caused by debris accumulation associated with arcing. | ||||||

| A switch having a long contact life is provided. A neutral contact blade is provided with a first neutral contact and a second neutral contact. A primary movable contact blade and a secondary movable contact blade are supported by these first and second neutral contacts, respectively, for seesaw motion. The operation of a lever causes the primary movable contact blade and the secondary movable contact blade through a pushrod to move in a seesaw motion in such a manner that a secondary movable contact provided on one end of the secondary movable contact blade contacts with an associated secondary fixed contact before a primary movable contact provided on one end of the primary movable contact blade contacts with an associated primary fixed contact, whereas after the primary movable contact of the primary movable contact blade is separated from the primary fixed contact, the secondary movable contact of the secondary movable contact blade is separated from the secondary fixed contact. This construction causes flow of a large closing current and any arc discharge to occur mainly on the side of the secondary movable contact blade. | ||||||
