Abstract:
A switching device structure having a top layer and a bottom layer, each layer comprising a body of magnetizable material, such as permalloy, disposed within a coil wherein an armature is suspended in a cavity between the top and bottom layers, the armature having ferromagnetic material disposed on a top and bottom surface thereof. Each body of magnetizable material may be pulsed by its respective coil to switch it from a magnetic state to a non-magnetic state and then subsequently pulsed by the coil to switch it from the non-magnetic state to a magnetic state.

Disclosed is a magnetic latching relay having an asymmetrical solenoid structure, the magnetic latching relay comprising a magnetic circuit portion, a contacting portion, and a drive portion; the magnetic circuit portion comprises a magnetic conductive component, a coil rack, and a coil; the drive portion comprises a movable iron core; further comprising two pieces of magnetic steel, the two magnets being respectively disposed on the two sides of a coil axis and being respectively adjacent to or in contact with the corresponding sides of the magnetic conductive component; and the two pieces of magnetic steel are within the movement range of the movable iron core in the axial direction of the coil, and are biased towards the moving direction of the movable iron core when a contact is in the closed state, such that the retaining force of the moving iron core is substantially the same in both closed and open states of contact. The present invention introduces biased magnetic steel into a relay having a solenoid magnetic circuit structure to make the relay a magnetic latching relay, for ensuring low heat dissipation while solving the problem of unbalanced action reset voltage of a solenoid magnetic circuit, thus improving product performance and operational reliability.
Abstract:
An electrical switching apparatus (2;50;90;100) includes a ferromagnetic frame (8) having first (110) and opposite second (112) portions, a ferromagnetic core (33) disposed therebetween, a permanent magnet (12) disposed on the first portion, a first tapered portion (113) on the opposite second portion; a coil (4) disposed about the core; and a ferromagnetic or magnetic armature (10) including a first portion (114), an opposite second portion (116) and a pivot portion (118) pivotally disposed on the core between the portions of the armature. The armature opposite second portion has a complementary second tapered portion (38) therein. In a first armature position, the armature first portion is magnetically attracted by the permanent magnet and the first and second tapered portions are moved apart with the coil de-energized. In a second armature position, the armature opposite second portion is magnetically attracted by the opposite second portion of the frame and the first tapered portion is moved into the second tapered portion with the coil energized.
Abstract:
The invention pertains to a method for detecting of a switch state in an electromechanical switching unit, wherein at least one permanent magnet (1), at least one magnetically excitable coil (2), one soft magnetic armature (3) seated in the coil (2) so as to rotate between two end positions (A, B) and being connected to at least one switch contact, and additional electrical components (9) are arranged in a housing, and wherein during a change in the armature (3) between the two end positions (A, B) the core permeability is changed and the particular magnetic working point is shifted. In order to create a method for detection of the switch state of an electromechanical switching unit which is convenient and reliable, and in particular which can be used in small-size relays, core permeabilities of the system are measured and evaluated to determine the switch state of the switching unit.
