An electromagnetic relay is designed so that it can be manufactured inexpensively and is based on a small unit size. The relay has a base group and a magnet system, it being possible to manufacture these separately and join them together as preassembled modular units. The base group has a base plate in which a component having a component wire is fixed in position. The magnet system has two flat pins each of which has a hole with a sharpened edge. When the magnet system is joined together with the base group, the flat pins are pushed into the base plate, in each case the edge at the wire component forming a contact created by an insulation displacement connection. The relay is preferably used in the automotive industry, especially if installation conditions are cramped.

Electromagnetic relay

The electrical switching apparatus includes a housing (10), a coil (20) arranged in the housing (10), at least two switch terminals (35,50,60) arranged in the housing (10), a magnetic angle piece (30) in the housing (10) including a core (32) for the coil (20) and an armature (42) resiliently mounted on the magnetic angle piece (30) for making electrical contact between two switch terminals (35,50,60). The magnetic angle piece is preferably made by a method including punching or stamping a nearly rectangular piece (39) from sheet metal, forming a U-shaped opening around a separately bendable tongue (32a) in a central region of the nearly rectangular piece (39) so that side pieces (30a) are formed on opposite sides of the U-shaped opening (38) and a connecting piece (31a) connects the side pieces (30a) on another end of the rectangular piece (39) opposite from one switch terminal; bending the separately bendable tongue (32a) at right angles to a remaining portion of the nearly rectangular piece (39) including the side pieces (30a) to form the core (32) of the coil (20) and bending the connecting piece (31a) at substantially right angles to form an upper portion (31) of the magnetic angle piece arranged substantially parallel to the core (32).
