Abstract: Disclosed are an arc path forming unit and a direct current relay comprising same. The arc path forming unit according to an embodiment of the present disclosure comprises a single magnet unit disposed on one side of a magnet frame, and a plurality of magnet units disposed on another side opposite to the one side. The plurality of magnet units are sequentially arranged in the longitudinal direction. One side of a magnet unit positioned between at least two of the plurality of magnet units and facing the single magnet unit is magnetized with the same polarity as that of one side of the single magnet unit facing the magnet unit. As such, magnetic fields in the direction of exerting repulsive forces on each other are formed in the central portion of the direct current relay. Accordingly, since the arc does not move to the central portion, damage to components disposed in the central portion can be prevented.

Abstract: Various high voltage systems may benefit from a suitable relay system. For example, a relay box may be provided with a shock and vibration resistant arrangement including a sealed coil box within the sealed relay box. For example, an apparatus can include a coil box containing coils, inside pole pieces, and permanent magnets, wherein the coils, inside pole pieces, and permanent magnets can be configured to actuate an armature assembly external to the coil box. The apparatus can also include outside pole pieces configured to move a relay armature of the armature assembly responsive to energizing of the coils. Moving the relay armature can include overcoming a latching of at least one of the permanent magnets.

Abstract: An electric switch is provided. The electric switch comprises a contact system, an actuation element, an engaging latch, and an actuator. The actuation element moves between an initial position and an actuation position to switch and changeover the contact system. The actuation element is located in a direction of the initial position by a force of a return spring. The engaging latch locks the actuation element in the initial position or the actuation position. A non-manual unlocking between the actuation element and the engaging latch is performed by the actuator.

Abstract: A method is disclosed for testing a latching magnet of a switch including a switching contact, formed from contact elements mechanically separated from one another for opening the switching contact; an electronic trip unit, to monitor current flowing via the contact elements and to perform a test for a current-dependent trip condition; an electrical energy store, forming a circuit with the winding of the latching magnet, the circuit being closed for a first closing time when the trip condition of the trip unit is met; and an actuator, actuable by closing off the circuit and configured to separate the contact elements. For test purposes, the circuit is closed for a second closing time, which is so short that separation of the contact elements by the actuator does not take place. A test is then performed to ascertain whether there is a current flowing via the winding of the latching magnet.

Abstract: An electromechanical microswitch, comprising first and second electromagnets mounted in spaced-apart orientation to one another where each electromagnetic has a field center located a first distance above the mounting surface. A permanent magnet is positioned between the electromagnets and includes a magnetic field center that is higher above the mounting surface than that of the electromagnets so that the permanent magnet is magnetically biased toward the mounting surface. A stripline switch element is mountable between the permanent magnet and mounting surface, and biased against circuit structures on the mounting surface, whereby the stripline switch element moves between first and second activated positions under influence of the electromagnets.
