Abstract

Electromagnet comprising a moveable part, i.e. a 'plunger', shaped as a flap (5) which closes a magnetic circuit when a current flows through a coil (1) enclosing at least a portion of the circuit, i.e. the 'core' (3), which is arranged on a base surface (4). The magnetic circuit comprises contact means (3, 8) shaped as tongues or the like, which are stamped out in the flap (5) and the base surface (4) respectively. The shape of the tongues may differ for different applications. The electromagnet may preferably be designed for blocking or locking functions.
