Abstract
An electromagnetic relay comprises a bobbin carrying a coil and having a longitudinal central bore through which an armature extends. A permanent magnet is disposed between the central webs of two generally U-shaped yokes, the legs of the yokes having end portions cooperating with end sections of the armature which project from the central bore of the bobbin. The armature is pivotal about a fulcrum formed near its one end, whereas the other end of the armature carries an actuating card for driving a contact spring disposed at the side, and parallel to, the bobbin. The contact spring is fixed at one end to a first contact terminal and has its other end disposed between two fixed contacts connected to second and third contact terminals. The three contact terminals are disposed along a line generally extending parallel to the bobbin. The coil is connected to two or three coil terminals arranged at the other side of the bobbin along a line which also extends generally parallel to the bobbin. The bobbin with the armature extending through its central bore, the yokes and the permanent magnet are together press-fitted in a recess of a base in which the contact and coil terminals are embedded.
