<p>A mechanical indicator element with binary action (6) is driven by a drive element (8) and carrier (2) via a driving axle (9a) which crosses the bearing axle (9). The driving axle is suspended in points in the bearing pedestal free of friction. When the switching coil (4) or the resetting coil (5) are excited, they attract the plunger (7) and follow a mechanical path via the push rod (3) and carrier (2). This path results in an angle of rotation on the driving axle which gives the desired binary action to the mechanical indicator element. It is made as a tube and responds to the interplay between the resetting coil and switching coil.</p> |
