An electromagnetic relay 1 includes: a base 28; a pair of fixed contact terminals 22 each including a fixed contact 38 and a first fulcrum 22d fixed to the base; a movable contact spring 18 including a pair of movable pieces, each of the movable pieces including a movable contact 36 contacting and separating from the fixed contact; an armature 16 that is coupled with the movable contact spring, and moves the movable contact spring by a rotary motion around a second fulcrum 16e; an electromagnetic device 31 that drives the armature; and a permanent magnet 12 that is arranged between the pair of fixed contact terminals and between the pair of movable pieces, and generates a magnetic field; wherein the first fulcrum and the second fulcrum are arranged mutually in opposite directions with respect to the movable contact or the fixed contact.

Provided is a relay having a structure for preventing deformation of a movable spring when it is caulked. A yoke of the relay has a protrusion for caulking inserted in the movable spring, and a bulge portion adjacent to the protrusion and having a height lower than a height of the protrusion. By providing the bulge portion to the yoke, the dimensional change in the caulking direction of the movable spring when the movable contact is caulked can be reduced.

A relay is described that comprises, for example, an electromagnet having a coil wounded on a winding frame and an iron core positioned in the winding frame, a movable terminal having an armature actuated by activation of the electromagnet, a movable spring attached to the armature and a movable contact attached to the movable spring, and a fixed contact opposed to the movable contact. The armature has a shape in which both ends of the armature in a direction perpendicular to an axial direction of the iron core are recessed relative to a center of the armature, and the armature does not exist in a thickness direction of a site which is cut to form the movable spring.

Provided is a relay comprising an electromagnet having a coil wounded on a winding frame, a movable contact moved by activation of the electromagnet, a fixed contact opposed to the movable contact, and a flange formed on an axial end of the winding frame. The flange has an inswept tapered shape, and at least a part of an outer peripheral portion of the flange has a chamfered shape or a rounded shape.

A first end portion includes a first contact. A second end portion includes a second contact. At least a first end portion, out of the first end portion and a second end portion, is curved to be folded back from a tip in one direction of the first end portion. The first contact is located in a folded-back part of the first end portion and faces the second contact.

The electromagnetic relay includes a contact unit, an electromagnet, an armature unit, and a base. The contact unit includes a fixed contact and a movable spring including a movable contact. The armature unit is movable in accordance with excitation of the electromagnet to allow the movable contact to move between a closed position in contact with the fixed contact and an open position away from the fixed contact. The base holds the contact unit and the electromagnet on a certain surface side. The movable contact is placed between the base and the fixed contact in an arrangement direction in which the base and the electromagnet are arranged. The armature unit includes a press part which causes movement of the movable contact by applying a pressing force to a certain surface facing the fixed contact, of the movable spring.

A switch in accordance with one aspect of the disclosure may include a housing connected to a first contact and configured to be rotatable, an electrode provided on an outer surface of the housing and connectable to a second contact outside the housing by rotation of the housing, a coil provided inside the housing and configured to generate a magnetic force, and a spring provided inside the housing and rotating the housing in response to the magnetic force generated by the coil.

A relay includes a case and a coil unit is located in the case. Multiple first legs each have the first end thereof connected to the coil unit, and the second end thereof extending beyond the case. A second leg has the first end thereof located in the case and forms a contact, and the second end of the second leg extends beyond the case. A third leg includes an upright section and a transverse section which extends from the upright section and located in the case. The upright section has one end thereof extending beyond the case. An armature has a connection section connected to the transverse section, and a main section located beneath the contact. The connection section increases conductive area and flexibility of the armature in the case.
