| In a circuit breaker of double break type, a first moving contact arm and a second moving contact arm are pivoted on a common pin shaft in a manner to move mechanically independent from each other and are electrically connected at the parts near the pivoted ends by a flexible conductor, such as a braided wires, and thereby stable and reliable contacts of the moving contacts on the stationary contacts are assured. | ||||||
| 162 | Multi-gap switch | US252623 | 1988-10-03 | US4893048A | 1990-01-09 | George A. Farrall |
| A power switch which comprises a plurality of contact pairs connected in series provides substantial operational advantages. Included in these advantages are fast operating speed and direct imposition of circuit opening. The individual contact pairs are preferably controlled by piezoelectric benders to provide a compact, lightweight switch. | ||||||
| 163 | Key switch with multiple contact points | US123554 | 1987-11-20 | US4866228A | 1989-09-12 | Osamu Kamishima |
| A key switch is disclosed wherein a key stem is slidably movable within a switch case. Upward movement of the key stem under spring bias causes electrical disconnection between a stationary contact and a movable leaf-spring terminal type contact both mounted within the switch case. The stationary contact is a wire engaging a sheet metal type leaf-spring terminal contact having notches to provide plural contact points therebetween. | ||||||
| 164 | Contact for strip line switch | US154262 | 1988-02-10 | US4808129A | 1989-02-28 | Stephen W. Kershner |
| A cantilever contact is disclosed of the type adapted to be incorporated into a switch system or array, which comprises at least a strip line comprising a plurality of like cantilever contacts arranged in end-to-end, overlapping relationship with each other. The strip line of such contacts is adapted to be connected to a transmission system, which has a characteristic impedance. The cantilever contact includes first and second ends, a first portion adjacent to the first end affixed to a support member, a second spring portion disposed intermediate to the first and second ends, a third contact portion disposed adjacent to the first affixed portion and on the other side of the first affixed portion with respect to the second spring portion, and a fourth contact portion disposed adjacent to the second end and freely suspended by the second spring portion with respect to the support member for contacting a third contact portion of an adjacent contact in the strip line. Each of the first and second ends of each contact is folded back upon itself such that its end is shielded from the adjacent contact and, instead, a rounded surface is presented thereto. Each cantilever contact has at least one bifurcating slot disposed longitudinally thereof and is dimensioned to ensure the longitudinal flexibility of the contact. In addition, each cantilever contact has at least a further bifurcating slot disposed longitudinally thereof and extending from the second end towards the first end a length selected such that the strip line of contacts has an aggregate impedance set to be substantially equal to the characteristic impedance. | ||||||
| 165 | Switch housing having fixed external nuts for attachment of contacts and terminals | US817107 | 1986-01-08 | US4695691A | 1987-09-22 | Henrik Leth-Olson; Lajos K. D. Marot |
| A switch housing includes two identical halves forming a top wall and a bottom wall each of which has transverse countersinks. The countersinks are provided with permanently secured polygonal nut members for receiving screws for fastening the mounting ends of L-shaped fixed contacts and external terminals. The countersinks also have elongated holes for receiving the contact ends of L-shaped contacts. | ||||||
| 166 | Polarized DC contactors | US274769 | 1981-06-18 | US4376271A | 1983-03-08 | Paul M. Gallatin; Roger L. Robertson |
| Means for causing the properly-polarized one of a pair of series-connected DC contactors to open before the other, depending upon the direction of load current flow. Load current is caused to link the magnetic circuit constituted by a contactor coil, frame and armature; with current flowing in a first direction, the linking has an additive effect, strengthening the MMF in the magnetic circuit. When current flows in the opposite direction, the MMF is weakened which allows the contactor to open more quickly. | ||||||
| 167 | Vacuum-type circuit breaker comprising series-connected vacuum interrupters within a grounded tank | US38669673 | 1973-08-08 | US3839612A | 1974-10-01 | BADEY P; OPPEL J |
| A high-voltage vacuum-type circuit breaker comprises a tubular grounded tank and a plurality of series-connected vacuum interrupters located within the tank. The interrupters are mounted in such positions that: (1) the longitudinal axes of the interrupter casings extend transversely of the central longitudinal axis of the tubular tank and (2) the movable contact rods of the interrupters project outwardly through the interrupter envelopes toward a single side of the tank. For operating the interrupters, there is provided a linkage extending between the interrupters adjacent the ends of the envelopes through which the movable contact rods extend.

| Embodiments of the disclosure pertain to a voltage regulator system having a voltage regulation controller and a transformer assembly. The transformer assembly includes a coil winding, a multi-contact tap arrangement connected to the coil winding, and a multifurcated tap changer system that includes a first tap changer having a contactor element which makes contact with a first contact of the multi-contact tap arrangement when the controller provides a positioning stimulus based on sensing a voltage deviation from a nominal output voltage of the voltage regulator system. The multifurcated tap changer system further includes a second tap changer that is mechanically ganged to the first tap changer and includes another contactor element arranged to automatically make contact with a second contact of the multi-contact tap arrangement when the contactor element of the first tap changer makes contact with the first contact of the multi-contact tap arrangement. | ||||||
| 180 | Relay having two electrically parallel contact springs | US15592022 | 2017-05-10 | US10032586B2 | 2018-07-24 | Richard Bayer |
| A relay with two current paths thermally connected in parallel is particularly fail-safe. In case of a failure of one main contact, the additional load current is led via the remaining functioning main contact. The failed main contact as well as the thermal connection between the two main contacts then serve as heat sinks, whereby the relay can continue to operate. | ||||||
