Abstract
In an electromagnetic relay, an electromagnet is constructed from an approximately U-shaped magnetic pole piece, an approximately U-shaped magnetic yoke, and an armature. One side leg of the magnetic pole piece, one side leg of the magnetic yoke, and the armature are accomodated in the central hole of a bobbin so that the efficiency of the conversion of electrical power into a driving force is increased.
