An electromagnetic relay includes a base, an electromagnet disposed on the base, an armature unit having a magnetically attractive member magnetically attractable by the electromagnet, a movable terminal unit mounted on the armature unit and including a first terminal member and a first contact, and a stationary terminal member mounted on the base. The first terminal member is a two-piece structure composed of a spring plate and a first leg. A ratio of the thickness of the first leg to the thickness of the spring plate ranges from 2 to 4. When the electromagnet is energized and de-energized, the first contact contacts and moves away from the second contact, respectively. A method of making the electromagnetic relay is also disclosed.

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.

The invention relates to an electromagnetic relay (1), more particularly a safety relay (1). This has a main body (10) and a coil system (20, 120) located thereon, the coil system (20, 120) having a coil (24, 124) and a yoke (25, 125) which extends through the coil (24, 124) along a winding axis (WA) of the coil (24, 124).
