A housing partially surrounds the conductive element and the biasing element. The biasing element and exerts compressive forces against the housing and the conductive element. The assembly may be installed as a modular unit on a carrier which is displaced during operation of the contactor. The housing shields the biasing element from plasma, arcs and debris during operation of the device. Multiple conductive elements and corresponding biasing elements may be includes in each assembly. | ||||||

| High-current, current-limiting circit interrupter having arcing contacts connected in parallel with the main contacts. Impetus means open the main contacts strikingly to switch the short-circuit current to the high-resistance arcing circuit. Electrodynamic means cause the arcing contacts to remain closed a short lapse of time after the transfer of the short-circuit current to the arcing circuit. Further electrodynamic means cause the arcing contacts to open sequentially. | ||||||
| 130 | Auxiliary contact interlock for electromagnetic contactor | US46833574 | 1974-05-08 | US3898596A | 1975-08-05 | RICHARDS EDWARD L; DOBROSIELSKI STEPHEN S |
| The auxiliary contact interlock for use with an electromagnetic contactor having a crossbar which in the open position of the contactor is subject to unlimited vertical bouncing incurred by ambient vibration, characterized by stationary and movable contacts within a housing, a movable contact carrier supported on a rod mounted within the housing for longitudinal movement between open and closed contact positions, the rod being biased in one of the open and closed positions by a kickout spring, the end of the rod external of the housing being depressed against the kickout spring to said one of the open and closed positions when the crossbar is in the open contact position of the electromagnetic contactor, a loading spring mounted on the rod and adjacent to the contact carrier for holding the rod in said one position and a shock spring having a greater spring constant than the loading spring on the rod and end-to-end abutment with the loading spring for maintaining the contact in said one position so long as the rod is deflected against the kickout spring by the crossbar.

| 131 | Molded case circuit breaker | US30229772 | 1972-10-30 | US3805199A | 1974-04-16 | TAZUKI S |
| A molded case circuit breaker comprising a contact arm movable between circuit closed and open positions, a collapsible mechanism including a releasable member having one end normally engaged with a latch member of an automatic trip unit, a pair of toggle links provided between the movable contact arm and the releasable member, and a tension spring stretched between a manually operable handle and a toggle knee of the toggle links, the other end of the releasable member having a wedge member swingably mounted thereto. When an automatic trip occurs, the wedge member slidably enters between one of the toggle links and a stationary pin secured to the molded case to prevent the contact arm from rebounding toward its circuit closed position.

| 132 | Current limiting device | US3764851D | 1972-10-13 | US3764851A | 1973-10-09 | HICKS J; PAICE D |
| This disclosure relates to a current limiting device having a first electrical conductor, and a second electrical conductor arranged to be displaced in a path from a fixed position. A plurality of discrete electrical conductors are arranged in tandem, and held in contiguous relationship between the first and second electrical conductors during normal circuit operating conditions. A plurality of chutes, arranged normal to the displacement path, are positioned in proximity to the electrical conductors. A member for displacing the second electrical conductor, moves the second electrical conductor a finite distance in response to a signal indicative of excessive current flow. When the second electrical conductor is displaced, a plurality of arcs are produced between successive discrete conductors, the debris products produced during arcing being exited through the chutes.

| 133 | Plug connection contact with high security against burning off | US3691511D | 1970-10-05 | US3691511A | 1972-09-12 | BILLMANN GERHARD LEONHARD EMIL |
| An electric connector for high circuit loads having an inner contact portion and an outer contact portion for the purposes of minimizing the arc encountered in switching high circuit loads. In an assembled position, a mating contact is electrically engaged by both the inner and the outer contact portions of the connector. When being removed from the connector, the mating contact disengages from the inner contact portion of the connector first, while maintaining electrical contact with the outer portion of the connector. As the mating contact element is further withdrawn, it disengages from the outer contact portion of the connector, and any arcing, occurring as a result of the discontinuity of low resistance contact, will occur between the mating contact element and the outer portion of the connector plug. The outer portion of the connector plug is composed of a material offering a high resistance to burning-off and is provided with an inwardly inclined surface at the entry portion of the connector to cause arcing to take place on such incline. The inner portion makes low resistance connection with the mating connector, and, by the action of the outer connector portion, is protected against the effects of arcing.

| 134 | Electrical switch having contacts provided with rollers | US3648003D | 1971-01-29 | US3648003A | 1972-03-07 | WIKTOR DOMINIK M |
| A knife-type electrical switch including a blade contact and a pair of roller contacts between which the blade contact moves when the switch closes. The rollers are rotatable about axes substantially perpendicular to the direction of blade movement between them. The rollers have tapered ends, and the blade edge facing the rollers diverges from the rollers. Each roller is carried by an arm mounted to pivot about a point spaced from the rollers, and spring means constantly urge the arms and hence the rollers toward each other.

| 135 | Double pole switch | US3622727D | 1969-12-01 | US3622727A | 1971-11-23 | PIGEON DALE W |
| The invention relates to double pole contact switches for use on automobile electrically operated systems such as the doors, windows and seats and, more particularly, to double pole contact switches wherein each contact set of the movable contact carrier is made up of a plurality of laminated sheet metal blades, with one blade having a movable contact, and a second blade having an independently movable arcing contact. The arcing contact is arranged and constructed to contact a stationary contact prior to electrical contact being made with the stationary contact by the movable contact. The function of the arcing contact is to extinguish or dissipate any contact arcing that may occur across the movable contact and stationary contact to prevent contact pitting.
