摘要： The problem to be overcome by the present disclosure is to improve the arc extinction performance of a contact device and an electromagnetic relay including the contact device. A first end portion (42) includes a first contact (F10). A second end portion (32) includes a second contact (M10). At least a first end portion (42), out of the first end portion (42) and a second end portion (32), is curved to be folded back from a tip (420) in one direction (S1) of the first end portion (42). The first contact (F10) is located in a folded-back part of the first end portion (42) and faces the second contact (M10).

摘要： An electromagnetic relay includes a fixed contact module including a fixed contact, a movable contact module including a movable contact disposed to face the fixed contact, an armature formed of a magnetic material and configured to move the movable contact module to bring the movable contact into and out of contact with the fixed contact, and an electromagnet configured to generate a magnetic field to move the armature. At least one of the fixed contact module and the movable contact module includes a joint at which different components are joined by riveting, and a film with a thermal conductivity higher than the thermal conductivity of the fixed contact module and the movable contact module is formed on at least one of the fixed contact module and the movable contact module including the joint.

摘要： The invention relates to a spring member (1) for an electric switching device (84) such as a cradle relay. The spring member (1) comprises a distal end (10) and a proximal end (8) opposite said distal end (10). A base portion (6) comprises said proximal end (10). A contact spring section (2) extends from the base portion (6) to the distal end (10) and is provided with a contacting spot (40). The spring member (1) comprises a return spring section (4) which extends from the base portion (6) alongside the contact spring portion (2). The spring member (1) according to the invention allows for a more compact and simpler design of the electric switching device (84) by replacing for example the armature (96).

摘要： Provided is an electromagnetic switch that can simultaneously drive a main contact mechanism and auxiliary contact mechanisms, and a contact position regulating method thereof. A main contact housing portion (6) that houses a main contact mechanism having a pair of fixed contacts (11a), (11b) fixedly disposed maintaining a predetermined interval and a movable contact (12) disposed so as to be connectable to and detachable from the pair of fixed contacts in a contact housing case (4), an auxiliary contact housing portion (7) that houses two or more auxiliary contact mechanisms (34A), (34B) having fixed contacts and movable contacts disposed so as to be connectable to and detachable from the fixed contacts, and an electromagnet unit (3) that moves the movable contact of the main contact mechanism and the movable contacts of the auxiliary contact mechanisms, are disposed in series.
