Abstract
An electromagnetic relay has a coil member serving as a base body, an armature disposed in an axial bore in the coil member, a yoke at least one section extending outside of the coil parallel to the coil axis, a contact spring with a first section disposed on the yoke and crimped at an end face thereof in front of one flange of the coil member, and at least one further section engaging an extension of the armature. Movement of the armature causes movement of a further portion of the yoke between two switching positions in contact with one of two stationary contact elements. The contact spring is disposed in a channel formed between a leg of the yoke and a cover for the relay. A long free spring length is thus obtained while still maintaining reliable sealing of the contact chamber and a low overall height of the relay.
