An electromagnetic relay having a coil core which carries a coil. The coil is connected to one end to the short limb of an L-shaped magnet yoke, on a long limb of the L-shaped magnet, a hinged armature is supported in a manner which allows the armature to pivot about a pivot axis on the long limb of the magnet. In order to achieve a precisely defined switching behavior which is concurrent for the relays of a series, the length of the coil core is produced by means of upsetting as a function of the height of the pivot axis above a base area of the magnet yoke on which the coil core is secured, with the result that the position of the hinged armature with respect to a pole face of the coil core is precisely defined.

Electromagnetic relay and method for the production thereof

Electromagnetic relay

An electromagnetic relay has a base plate, a magnetic yoke mounted on the base plate, a relay winding, a spool core supporting the relay winding, a hinged armature arranged turnably on the spool core, a switching contact supported on the hinged armature, a counter contact cooperating with the switching contact, an adjusting part adjusting a contact distance between the countercontact and the switching contact when the armature is retracted and having at least one stretching zone extending substantially in a movement direction of the armature, the adjusting part forming a lever having a free end cooperating with the switching contact and another end anchored on the base plate, and an adjusting web provided with the stretching zone and engaging at a location between the ends with the adjusting part, so that by extension of the adjusting web to adjust the contact distance at the free end of the adjusting part.
