摘要

The armature is higned in a supporting frame, and is operated by a control element, and in turn abruptly operates a contact support interacting with fixed contacts. Magnetic force is generated by a permanent magnet (9) which is loosely held in a recess (10) in the frame (1) between the armature (4) and an iron core (11) which is positioned to it. It is held in the recess by an adjustable iron core which is fastened to the frame.
