Abstract: 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.

Abstract: An electromagnetic relay for consumers with a high switch-on current peak has a main contact and a preliminary contact on legs which extend near one another. The legs carrying the main and preliminary contacts are connected at both sides with another leg via connecting webs and have each a stretch zone between a common connecting yoke of the legs and the connecting webs. At the stretch zones the main and preliminary contacts are adjusted independently of one another by means of squeezing the material of the contact carrier.

Abstract: 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.
