摘要：A drive device for an isolating switch has a rotatably supported spindle (14)which is coupled in a driven manner to the moving switching piece of the isolating switchsuch that, on rotation of the spindle (14), the moving switching piece is operated. On thespindle (14) there is mounted a gearwheel (37) which engages with a toothed drive (38)coupled to an electric motor drive, to rotate the spindle and hence to operate themoving switching piece. The spindle (14) is additionally rotatable with a hand-crank (43) aswell. To simplify this manual operation and to ensure that the gearwheel (37) is coupledto the toothed drive (38) when the hand-crank (43) is pulled, the gearwheel (37) can bepushed between two positions on the spindle (14), by the hand-crank (43), such that inthe first position it engages with the toothed drive (38) and in the second position isreleased from the toothed drive (38). Between the hand-crank (43) and the spindle (14)there are provided controllable locking elements (46, 49, 50) which release the hand-crank (43) only in the first position of the gearwheel (37), and only then allow the hand-crank (14) to be pulled out.
