An electromagnetic relay includes an electromagnet block having coils wound about the bodies of spools through which iron cores are provided. The electromagnet block is accommodated in a concave part that opens upward of a box-shaped case such that the shaft centers of the iron cores can be orthogonal to the bottom surface of the box-shaped case. The electromagnet block is excited and demagnetized by the passage and break of electric current through the coils so that a contact mechanism can be driven by a movable iron piece that is absorbed to and leaves magnetic pole portions at the upper ends of the iron cores. In this case, the electromagnet block is hung at the upper opening edge of the box-shaped case such that a space can be provided between the bottom surface of the box-shaped case and the electromagnet block. |
