Abstract
An activating magnet has a magnet housing (1), a pole element (10) arranged at one end of the magnet housing, a magnetic coil (13) surrounding the magnet housing and the pole element, and a magnet armature (3) movably housed in a magnet housing. An activating spring (20), biased between said magnet armature (3) and the pole element, and an activating member (5) are arranged on the side of the magnet armature opposite the pole element. In order to arrange an emergency manual activation on the magnet, a hand bolt (18), particularly a manually activated hand bolt, is provided on the side opposite the activating member. The hand bolt (18) is connected with the magnet armature to make it possible to exert a tensile force on the magnet armature.
