A contact device includes a fixed contact, a movable contact, a housing, and an arc extinguishing member. The movable contact moves between a closed position where the movable contact contacts the fixed contact and an open position where the movable contact is separate from fixed contact. The housing houses the fixed contact and the movable contact. The arc extinguishing member is movably disposed in the housing and discharges an arc extinguishing gas. The arc extinguishing member is disposed facing a gap between the fixed contact and the movable contact when the movable contact is in the open position.

Systems, devices, and methods for an electrical switch including: an enclosure; a hinged armature disposed within the enclosure; a moveable contact electrically coupled to the hinged armature and disposed substantially parallel to the hinged armature; and a rib positioned between the hinged armature and an outer edge of the electrical switch, where the rib transfers external forces applied to the electrical switch to the enclosure by limiting movement of the hinged armature towards an outer edge of the electrical switch.

A contact apparatus includes a base body, two fixed contacts, and a moving contact component. The base body has an inner cavity. The two fixed contacts are fastened to the base body at intervals and extend into the inner cavity of the base body. The moving contact component includes a pushing member and a moving contact. The pushing member is movably disposed through the base body. The moving contact is mounted on the pushing member and is located in the inner cavity of the base body. The pushing member is configured to drive the moving contact to move, so that the moving contact is in contact with or is separated from the two fixed contacts.

A contactor includes a pair of fixed contacts, a movable contact element configured to contact the pair of fixed contacts and to be separated from the pair of fixed contacts, a movable shaft configured to move in an axial direction as to cause the movable contact element to contact the pair of fixed contacts and to be separated from the pair of fixed contacts, and a partition-wall component disposed opposite to the pair of fixed contacts with respect to the movable contact element. The first partition-wall component includes a partition wall provided around the movable shaft. The first partition wall is configured to move synchronously with at least one of the movable contact element and the movable shaft.

An electromagnetic relay includes a base, an electromagnetic block disposed on an upper surface of the base, a movable iron piece that rotates based on excitation/non-excitation of the electromagnetic block, a movable contact piece that rotates integrally with the movable iron piece, a movable contact fixed to a free end of the movable contact piece, a fixed contact disposed so as to come into or out of contact with the movable contact in association with rotation of the movable contact piece, and a magnetic field generation unit disposed so as to attract an arc generated between the movable contact and the fixed contact in a direction that, as seen from the fixed contact, is opposite to the movable contact and the base.

The fixed contact member includes a fixed contact. The movable contact member includes a movable contact and is movable between a position where the movable contact is in contact with the fixed contact and a position where the movable contact is away from the fixed contact. The permanent magnet forms a magnetic field around the fixed contact. The case is for accommodating at least the fixed contact member and the movable contact member. Further, the case includes an accommodation part which is partitioned from an internal space of the case and is for accommodating the permanent magnet through an opening thereof directed to an outside of the case.

Examples of a relay are described, with which the characteristics of the relay such as the operating voltage can be prevented from changing, even when impact is applied to the relay. The relay has an electromagnet, an armature which pivots about a pivot axis by excitation of the electromagnet, a pressing member attached to a tip of the armature, and a terminal which is pressed by the pressing member, wherein the armature comprises a plate-like insertion part which extends in a direction parallel to the pivot axis, and a guide groove provided in the insertion part and which extends in a direction parallel to the pivot axis, and the pressing member comprises an enclosure which is open on one end, and a part of the enclosure is inserted into the guide groove.
