121 Electromagnetic relay US837798 1992-02-19 US5274348A 1993-12-28 Richard A. Vernier; Thomas H. Vaughn
An electromagnetic relay to be used in applications such as DC motor reversing. The relay consists of two electromagnetic devices in a single enclosure with contacts configured in a so-called "H-bridge" circuit. Each of the devices has a movable contact element, while both devices have a common pair of normally closed and normally open stationary contact elements. Both electromagnetic devices have coil bobbins which are preferably identical in shape and are locked together by means of the common stationary contact elements without a need of additional fastening means. In this manner, the number of parts is minimized and the amount of adjustment required is reduced.
122 Seesaw type mechanically interlocked electromagnetic switch for controlling forward/reverse current systems US530325 1990-05-30 US5087903A 1992-02-11 Han-Tsung Chiu
A seesaw electromagnetic switch for controlling a chain/forward/reverse current system includes a seesaw assembly and an exciter set. Springs are provided and disposed between the seesaw assembly and the exciter set to balance the seesaw assembly. Because of this balanced position, even if two coils parallelly disposed in the exciter set are incidently provided with current at the same time and thereby cause the seesaw assembly to swing, no current will flow through the main circuit and no short-circuit will occur in either the forward rotation circuit or the reverse rotation circuit, protecting the motor in use from burning out. The wiring is simplified and the volume of the electromagnetic switch is reduced by the closely and parallelly disposed coils of the exciter set, by the multiple terminals provided on top of an upper casing of the switch, and by the double-wall structure of the main casing of the switch which allows conductors to pass through side openings and a bottom space formed between the two walls of the main casing, connecting contacts at two opposite sides of the switch to form the forward circuit and the reverse circuit.
123 Reversing circuit for direction reversal in direct current drives US332451 1989-03-08 US4947285A 1990-08-07 Anton Happach
For the purpose of achieving an efficient and long-lived switching contact making on the basis of a structural design saving space and material, a reversing circuit for direction reversal in the case of direct current drives comprises four single-pole contactors which are arranged in a square and which are provided with coils 1 and with contact bridges 2 as well as four contact pieces 3 for connecting the outer terminals with fixed contacts formed by said contact pieces 3, the contact pieces 3 being arranged on one side of the coils in a square within one plane.
124 Electromagnetic relay US79442 1987-07-30 US4816794A 1989-03-28 Hirohumi Nagao; Kenichi Matsuo; Muneo Nakata
The electromagnetic relay has a pair of normally closed and normally open fixed terminals which are disposed opposing each other. At least two normally closed fixed contacts are mounted on the normally closed fixed terminal, and at least two normally open fixed contacts are mounted on the normally open fixed terminal. The normally closed and normally open fixed terminals are commonly used by a plurality of relay units. Therefore, the relay can be small enough to be installed on a small area, and allows high-density electric circuits to be provided on circuit boards.
125 Terminal assembly for electrical apparatus US777277 1985-09-18 US4632497A 1986-12-30 Gerd C. Boysen
A three phase motor reversing assembly includes two contactors interconnected with solid flat bus bars. The terminal assembly employed on the contactors includes a stationary terminal and a captive threaded fastener slidably retained within a pocket formed from the insulating material of the contactor base. The sliding captive threaded fastener allows the bus bars used for interconnection to be mounted on the underside of the stationary terminal. External connections are made to a cable clamping device mounted on top of the stationary terminal. A bolt is inserted through all of the connections to be made and threaded into the captive threaded fastener. As the bolt is tightened, the captive threaded fastener provides a counter-torque and is drawn up until tight contact is established.
126 Polarized electromagnet having three states and a control circuit for said electromagnet US756511 1985-07-18 US4609899A 1986-09-02 Gerard Koehler
A three-state polarized electromagnet comprises a stationary system (1) surrounded by a coil (5) and a moving system (7). Each system consists of a permanent magnet (2; 14) fitted with pole pieces (3, 4; 12, 13). The ends of the pole pieces are bent-back towards each other in order to define four air-gaps (E1 to E4) for permitting displacement of the moving system (7) between two end positions. One end portion of a pole piece forms part of only one air-gap and the air-gap faces are joined to pole faces of permanent magnets having the same polarity in order to reduce to zero the fluxes within the air-gaps which are closed when no excitation is applied and in order to permit a return to a stable central position.

129 Electromagnetic contactor US286659 1981-07-24 US4409575A 1983-10-11 Masanao Hisadome
An electromagnetic contactor provided with two units of electromagnetic contactors. When one of units is excited to move a movable iron core, the movement of movable iron core forces a roller, which is arranged between two units, into the other unit to prevent a movable iron core of the other unit from being moved.

A contactor includes an actuator which is slidably mounted to a base and carries a set of movable contacts into engagement with a set of stationary contacts when an associated electromagnet is energized. The stationary contacts are located above the electromagnet and are connected to a set of contactor input terminals and a first set of contactor output terminals which extend through the top of the contact enclosure. A second set of contactor output terminals are mounted to the base below the electromagnet where they are easily connected to overload relays. A set of bus bars are mounted to the base and connect the first and second set of contactor output terminals.
