ABSTRACT:
An activating magnet, particularly a stroke magnet, has a magnet housing (15) which closely surrounds the periphery of the coil (7) and abuts the spool (8) thereof. An armature (1) is arranged within the coil so as to be axially moveable therein, and a pressure-proof junction box (38) is rigidly connected with the magnet housing in which the connections (24) for the coil are located. In order to create a much simpler and more economical construction for a pressure-proof pole tube (3,4,6) on which the coil is arranged. The magnet housing is pressure-proof and abuts the pole tube on both sides of the coil, and a pole core (5) is penetrated by the activating ram (2), whereby the pole core on one side and the magnet housing on the other side are rigidly connected with each other by means of a connecting means (22). The connections for the coil are guided through and out of the wall of the magnet housing and the junction box is rigidly connected to the magnet housing on the side thereof where the coil connections protrude.
