A high voltage relay resistant to instantaneous high-current impact is disclosed, and includes an electromagnet system, a control system, a contact system, and a base support. In the present solution, an electromagnetic force generated by the contact system is used to resolve a problem of contact separation caused by an electric repulsion force generated by an instantaneous high-current.

The invention relates to an electric switch that serves to switch on and/or off electric devices and for this purpose has a contact system in the switch housing. By means of a manual actuating element or a remotely controlled actuator, a switching operation can be effected.

A base of a relay has a leg extending in a contact/separation direction between contacts, and the leg is configured to come into contact with a yoke when the base is incorporated into a case. The leg is spaced away from an upper part of an armature by a distance. This distance is determined so that an upper surface of the armature does not come into contact with the leg in a normal operation of the armature, but the upper surface of the armature comes into contact with a lower surface of the leg when the armature jumps up beyond a movable range thereof due to, for example, a strong impact applied to a vehicle on which the relay is mounted.

An electromagnetic relay includes a fixed spring, a fixed contact configured to be swaged so as to be attached to the fixed spring, a movable spring, and a movable contact provided on the movable spring so as to be capable of making contact with the fixed contact, wherein a swaged portion of the fixed contact is formed so as not to protrude from a surface of the fixed spring.

An electromagnetic contactor with connecting spring including: a movable core contact plate section that is inserted into a through hole formed in a movable core and comes into contact with a contact support side of the through hole; and a pair of curved plate sections each joined to either end of the movable core contact plate section and housed in connecting spring tip housing sections formed in the contact support, the sides of which opposite to a contact surface of the movable core contact plate section come into contact with the connecting spring tip housing sections. In the movable core contact plate section, a depressed section is formed in a direction crossing a longitudinal direction to bulge out to an opposite side to the contact support side is formed, and contact sections that come into contact with the through hole are formed on both ends of the depressed section.

A switching device for opening and closing an electrical line, including: two fixed contact terminals separated from one another, an operating member, comprising a contact piece, at least one flexible strip comprising at least one end part attached to a fixed support, the flexible strip or strips being adapted to exert a return force on the contact piece to return it from its closed position to its open position in the absence of a motive force on the operating member, the operating member comprising two electrically insulating pusher arms, spaced apart from one another and each attached to an end part of the contact piece; each flexible strip comprising two other end parts, each attached to one of the two push arms or to a part of the operating member that is itself attached to, or forms an integral part of, one of the pusher arms.

An electromagnetic relay includes a movable terminal including a movable contact, a fixed terminal including a fixed contact that faces the movable contact, first irons disposed on one of the fixed terminal and the movable terminal, and a second iron disposed on another one of the fixed terminal and the movable terminal such that the second iron at least partially overlaps both of the first irons.
