ABSTRACT:
An electromagnetic relay having superior visibility and a light-emitting device easy to mount. A coil block and a contact opening and closing mechanism are disposed on a base plate and covered with a case, and the electromagnetic relay magnetizes and demagnetizes the coil block via coil terminals to turn a movable core and moves a movable contact part to open and close a contact. Electrical connection portions of the coil terminals are projected upwardly through the top side of the case. A light-emitting device which emits light by the energization of the coil terminals and a holder which holds the light-emitting device are disposed on the top side of the case on the side opposite to a position where the electrical connection portions of the coil terminals of the case are projected. Lead wires connected to the light-emitting device are electrically connected to the electrical connection portions of the coil terminals.
