ABSTRACT:
A compact electromagnetic relay of the type having an insulative base (1) adapted to receive an electromagnetic assembly (2, 3, 4) on one side of its partition wall (15) and a contact assembly (6) on the other side includes especially adapted armature (3) and pusher (5). The armature has one leg (32) that is bifurcated to form a slotted opening (324) communicating with a socket (323). The shaft region (55) of the pusher has two cross-sectional dimensions of different size. One dimension d1 allows the slotted opening to freely pass over it while the other dimension d2 prevents the socket from disengaging with the pusher when the armature is rotated to assume its working position.
