An electromagnetic relay is provided with a housing; a first fixed contact terminal and a second fixed contact terminal; a movable contact, a movable shaft with one end connected to the movable contact, and a coil spring placed between the movable contact and an insulating wall in a chamber in the housing. The coil spring configured to bias movable contact points toward the opposing fixed contact points. The movable contact includes a contact body which includes a connection hole configured to receive the movable shaft and allow the movable shaft to travel relatively in the contact movement direction. The movable shaft includes a second holder that together with the first holder retains the coil spring.

An electromagnetic device includes a spool having a cylindrical body with a through hole, a secondary coil formed in a spiral shape along an outer peripheral surface of the cylindrical body and formed with a closed circuit by metal plating, and a primary coil formed of a conductive wire wound around the secondary coil via an insulating material covering the secondary coil. An induced current, generated by applying a voltage to any one of the primary coil and the secondary coil, is allowed to flow to the other coil different from the one coil.

This bobbin includes: a cylindrical winding portion, a first partition portion and a second partition portion, wherein the first partition portion has lead-in cutout portions through which the coil wire to be wound on the upper side and the coil wire to be wound on the lower side are to be respectively introduced, and lead-out cutout portions through which the coil wire to be wound on the upper side and the coil wire to be wound on the lower side are to be respectively led out, and the first partition portion has, on a winding portion side thereof, a step formed in a zone including a range between the lead-out cutout portion for the coil wire to be wound on the lower side and the lead-in cutout portion for the coil wire to be wound on the upper side.

Provided is a relay, with which an insulation distance can be maintained while preventing an increase in size of the relay. The relay has a coil, an iron core, an armature which moves by excitation of the coil, a contact terminal which displaces in accordance with the movement of the armature, a pressing member which is attached to the armature and which presses the contact terminal, and a base block having a wall arranged between a first area in which the coil and the iron core are arranged, and a second area in which the contact terminal and the pressing member are arranged, wherein the armature comprises a first portion arranged in the first area and a second portion extending from the first portion and arranged in the second area, and the pressing member is affixed to the second portion.

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.
