(2) End position lock End position lock Only those control ports, for which it is necessary to hold the control lever in a deflected position are equipped with end position locks. Electromagnetic lock An additional spring (7), which is fitted below an additional plate (12) warns, by means of an increased force, which is required for compressing this spring, that the plunger (5) and the control lever (1) have almost reached their end position. When this threshold is overcome, a ring (10) contacts the solenoid armature (11) ; if the solenoid is energized, then control lever (1) is held in its end position by magnetic force. This lock is released automatically when the solenoid is deenergized.
