Abstract:
1. An electromagnetic relay comprising: an electromagnet device having an electromagnet in which an iron core is attached to a bobbin with a coil wound thereon, and an armature attracted to or separated from the iron core according to voltage applied to the coil; a contact portion openable and closable according to a movement of the armature, the contact portion including a first fixed contact member in which a first fixed contact is arranged, a second fixed contact member in which a second fixed contact is arranged, a first movable contact member in which a first movable contact opposed to the first fixed contact is arranged and a second movable contact member in which a second movable contact opposed to the second fixed contact is arranged, wherein the first and second movable contact members operate according to a movement of the armature; a printed board to which the first and second fixed contact members and the first and second movable contact members are respectively electrically connected, including an electrical conductive portion electrically connecting the first movable contact member to the second movable contact member; and a first contact terminal member and a second contact terminal member, which are electrically connected respectively to the first fixed contact member and the second fixed contact member through the printed board and protrude from the printed board and adapted to be connected to electrical parts provided outside; wherein the printed board forms a terminal connecting circuit in which, when the first fixed contact and the first movable contact are in contact with each other and the second fixed contact and the second movable contact are in contact with each other, mutually contacting first fixed and movable contacts and mutually contacting second fixed and movable contacts are connected to each other in series between the first contact terminal member and the second contact terminal member.
