The fault condition causes a Curie metal element electrically coupled to at least one of the stationary contacts to release a magnetic latch. The release causes a trip rotor of the trip assembly to rotate a rotor assembly. This rotation causes ends of a movable contact of the rotor assembly to electrically disengage the stationary contacts, thereby opening the circuit. The switch also includes a handle for manually opening and closing the electrical circuit in fault and non-fault conditions. Actuation of the handle coupled to the rotor assembly via a spring-loaded rotor causes the movable contact ends to selectively engage or disengage the stationary contacts.Type: ApplicationFiled: May 8, 2008Publication date: November 12, 2009Applicant: Cooper Technologies CompanyInventors: Nicholas Brusky, Kurt Lawrence Lindsey

Patent number: 7595710Abstract: An electrical contact assembly includes a magnetic latch solenoid for actuating a moveable contact of a contact pair. The magnetic latch solenoid includes a magnet that latches the contact assembly in an open position, and a coil that moves an armature to the latched position under current in one polarity, and disrupts the permanent magnet field to release the armature from the latched position under current in a reverse polarity. A spring biases the contacts to the closed position. The spring is separate from the magnetic latch solenoid. The contact assembly may also include a printed circuit board for providing pulses to the coil to operate the assembly. The contact assembly is part of a remote operated circuit breaker assembly.Type: GrantFiled: June 27, 2007Date of Patent: September 29, 2009Assignee: Siemens Energy & Automation, Inc.Inventors: John DeBoer, Brian Timothy McCoy

Patent number: 7350285Abstract: A method of manufacturing a movable contact unit includes manufacturing a movable contact, sticking the movable contact to a base sheet made of insulating resin, and applying demagnetization to the movable contact so that the residual magnetic flux density is smaller than the operation magnetic flux density of the magnetic sensor. In manufacturing the movable contact, elastic metal plate material is processed into a downwardly opening dome shape to form the movable contact. In a method of manufacturing a switch panel, the movable contact unit is overlaid on a wiring board having a contact, including pair an outer fixed contact and a central fixed contact, that corresponds to the movable contact so that the lower end of the outer periphery of the movable contact is mounted on the outer fixed contact.Type: GrantFiled: November 2, 2006Date of Patent: April 1, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hideki Mitsuoka, Hiromichi Koyama

Patent number: 6975191Abstract: A resettable switching device, e.g. a relay, comprises a fixed contact (18) and a movable contact (28). A solenoid (12) is fixed relative to the fixed contact and a ferromagnetic plunger (20) carries the movable contact. A spring (24) biases the plunger away from the fixed contact so the device is normally open. When the device is set a further ferromagnetic element, e.g. a plunger (22), holds the first plunger (20) in a closed-contact position by magnetic attraction against the action of the spring (24). When a predetermined current condition exists in the solenoid the magnetic attraction between the element and plunger is reduced below the level necessary to hold the plunger so that the movable contact disengages the fixed contact.Type: GrantFiled: January 27, 2003Date of Patent: December 13, 2005Assignee: Tripco LimitedInventor: Patrick Ward

Patent number: 6677842Abstract: A load-disconnecting switch has a permanent-magnetic holding circuit. A coil (5), upon excitation thereof, generates a magnetic flux that is opposite to the magnetic flux of the permanent magnet (9). The armature (6) is biassed to an open position by an armature spring (10), so that the armature spring (10), when a defined operational excitation is exceeded, detaches the armature (6) from the core (7) of the magnet system, allowing said armature to open and thereby disconnecting a switching contact (15) and a fixed contact (16). The load-disconnecting switch can be switched on again by means of a spring clip (12) acting on said armature (6).Type: GrantFiled: July 26, 2002Date of Patent: January 13, 2004Assignee: Tyco Electronics Logistics AGInventors: Martin Hanke, Bernd Saffian, Thomas Hähnel, Rainer Vogel, Karsten Pietsch
