The armature is pivoted on one of the legs with the pivoted leg being arranged adjacent to an electromagnetic field producing structure including an electrically energizable coil. A first movable electrical contact carrying means is arranged to cooperate with a first one of the legs of the armature to produce a motion of a first electrical contact between a first and a second position in response to an energized and a non-energized state of the coil, respectively. Concurrently, a second movable electrical contact carrying means is arranged to cooperate with the other or second leg of the armature to produce a motion of a second electrical contact between a first and a second position in response to an energized and deenergized state of the coil, respectively. The coil is located in respectively. The coil is located in the bight of the U-shaped armature with the pivoted first leg being urged by a spring away from the coil. Since the legs of the armature are on opposite sides of the coil, the motions of the first and second arms induced by the coil are in the same rotational directions. Fixed electrical contacts are arranged to cooperate with the first and second movable contacts to produce corresponding electrical connections therewith in the first and second positions of the first and second movable contacts.

Monostable holding electromagnetic relay comprising an armature pivotable against pole masses and contact springs, and a permanent magnet magnetically holding the armature against one of its stops, characterized in that the magnetic resistance for the flux of the permanent magnet, which, when the armature is applied against the other of its stops, passes through the corresponding pole mass and the armature, is strong enough so that the value of the permanent magnetic force acting on the armature or less, than the value of the force exerted by the springs, of contact on the armature at this stop, this magnetic resistance being able to be made greater by inserting an air gap. vs. The invention finds its main application in electromagnetic relays.

Modular switchgear

A switchgear apparatus includes a vacuum interrupter assembly having a movable contact and a stationary contact, a main housing surrounding the vacuum interrupter assembly, and a first terminal electrically coupled to one of the movable contact and the stationary contact, the first terminal extending from the main housing along a first axis. The switchgear apparatus also includes a second terminal electrically coupled to the other of the movable contact and the stationary contact, the second terminal extending from the main housing along a second axis, and a mounting head couplable to the main housing in a plurality of orientations about the first axis.
