An electromagnetic relay system is constituted by containing an electromagnetic relay arranged in a case and including a coil, a movable contact and a plurality of fixed contacts, a positive terminal and a negative terminal formed to project from the case, and load terminals formed to project from the case and connectable to a motor. An electric current flowing in the motor is controlled by controlling an electric current flowing in the coil. A ground line extended from the coil is connected to the negative terminal via a coil spring in the case.
42 Multipolar electromagnetic switching module US09625964 2000-07-26 US06472837B1 2002-10-29 Yann Caporalin; Bernard Fournier; Xavier Person; Jean-Marc Romillon
The present invention relates to a multipolar electromagnetic switching module designed to be connected by line connections (t1, t2, t3) to a main electromagnetic switching device (AP) and by load connections (U, V, W, u, v, w) to at least one motor and having, in a unit (Bo), between said connections, several load paths fitted with switching poles whose contacts are always alternately closed and controlled by a switching electromagnet (EI) driven by a control circuit, each of the switching poles (C1, C2, C3) consisting of a movable contact holder (Pc) between two conductors (Cf1, Cf2) bearing fixed contacts characterized in that, for each pole, the movable contact holder (Pc) comprises two parallel loop-shaped conductors (Cm1, Cm2) connected to a connection (T1, T2, T3) and that the two fixed contact parts (Cf1, Cf2) are loop-shaped and connected to connections (U, V, W).
43 Change-over switch US499775 1995-07-06 US5679935A 1997-10-21 Hidekazu Baba; Keisaku Zenmei; Shuzo Isozumi
A moving contact assembly to which a moving contact is fitted so as to allow a normally open common fixed contact part to elude the moving contact and axially pass through is mounted detachably on a fixed core. A contact mold having a normally closed fixed contact part and a cap switch provided with a normally open fixed contact part, a normally closed common fixed contact part, and a normally open common fixed contact part are made axially separable. The contact mold is turned 90 degrees in one direction to allow the normally open common fixed contact part to elude the moving contact and axially pass through. Thus, when the contact mold is turned 90 degrees in the other direction to the contact mold's former condition, the moving contact can be positioned within a recessed groove of a common fixed contact.
44 Digital modular microprocessor based electrical contactor system US933282 1992-08-21 US5506485A 1996-04-09 Denis A. Mueller; Marlan L. Winter
A controller incorporating a push button station controls a plurality of electrical contactors in a modular multicontactor system using three-wire serial data links. All information exchange is initiated and controlled by the controller using a simple four-byte protocol which places very little burden on the contactors. The controller can also communicate with and receive commands from devices on a network through an interface using the same four-byte message protocol, but with the interface acting as the master and the controller as the slave. When used in a reversing and two-speed motor controller configuration, the controller manages sequencing of the contactors, including delays, and passes thermal image data between contactors.
45 Time delay relay arrangement US818331 1992-01-09 US5296786A 1994-03-22 Chris X. Habisohn; Michael R. A. Habisohn
A voltage switching arrangement for an electrical power control system including a plurality of switches for connecting and disconnecting voltage from the input to a power transfer network which provides power for a load. A time delay circuit prevents the voltage connected to the input to the power transfer network from being disconnected for a predetermined time period after the control system has been turned off. The power transfer network switches from an on-mode to the off-mode during said time delay period. The voltage connecting switches include an electromechanical DC relay, and the time delay circuit includes a capacitor cooperating with the relay to maintain the relay energized for the time delay period after the control system has been turned off. Safeguards are provided to prevent simultaneous connection of voltage in the forward and reverse directions to the input of the power transfer network.

51 Reversing contactor for a three-phase motor US723659 1985-04-16 US4618807A 1986-10-21 Edgar Wiessner; Werner Harbauer; Klaus-Dieter Paul
This invention pertains to a three-phase reversing contactor with fixed-mounted contact parts serving the input and the output, and a connection by contact bridges from the input to the output. A common drive mechanism is provided for all the contact bridges, and a shift mechanism to change the configuration of the contact bridges, while in the OPEN position, relative to the fixed-mounted contact parts is also provided. Through the application of the two independently movable contact bridge carriers, which by use of an auxiliary magnet can be selectively brought into functional contact with the common drive mechanism by a reversing yoke, the drive output for the auxiliary magnets can be kept low. As there is a fixed configuration of contact bridges to the fixed-mounted contact parts, the major wiring work can be performed in the shop by the use of correspondingly formed fixed-mounted contact parts.
52 Electromagnetic starter for reversible motor US776640 1985-09-16 US4617541A 1986-10-14 Chiu-Hsiung Chuang
A starter for a reversible motor has a single outer casing and one operating switch for controlling the forward or reverse rotation of the motor. The starter uses only ten pairs of electric contacts instead of the twenty pairs of contacts in a conventional starter. A safety means is provided which can turn off the undesired actuation circuit of the electromagnet. And another important feature of the starter is an adjustable screw with a coil spring sleeved thereon to assure the right movable contacts being closed in the starter without closing undesired contacts.

A switching circuit having hybrid contactors connects the three output lines of a 3 phase AC power source to three input lines of a load, such as a motor and the like. A single pair of relay contacts is used to directly connect one output line of the AC power source to one input line of the load, whereas each of the other two phases of the AC power source are supplied to the load by one of a pair of pilot relay contacts in series with a diode-shunted one of a pair of master relay contacts. Only two extra pilot relays are used to provide a reversing function. The switching circuit further includes a zero-crossing detector, a phase-sequence detector, a control circuit including four flip-flops arranged in a tumble-down chain and a single distribution circuit having a data select circuit. The control circuit causes the making and breaking of the contacts at particular times, and in a sequence, such that arcing is prevented.

59 Safety switching device for setting a safety-related device to a safe state US13555286 2012-07-23 US08675330B2 2014-03-18 Andre Korrek
A safety switching device, with which a safety-related device, can be set into a safe state. The safety switching device has a microprocessor or microcontroller, which can set an electric drive to be protected into a safe state both if an emergency circuit breaker, protective door switch, and/or two-hand switch is activated and also if there is faulty operation of the safety-related device or electric drive. For this purpose, the microprocessor is implemented such that it can determine from at least one analog signal to be measured whether a predetermined parameter lies outside a predetermined operating range. In addition, the microprocessor can be a component of a safety device which is constructed for multiple-channel control of a safety-related electric drive. In this way, the safety switching device can respond to several safety functions independent of each other in order to set an electric drive into a safe state.
