Abstract (en)
[origin: EP0120409A2] 1. Drive device for actuating a rotary isolating switch, with a contact tube (34) pivoted by a drive shaft (52), characterized in that there is, between the drive shaft (52) and the contact tube (34), a drive lever (50), to one end of which the drive shaft (52) is fastened and on the other end of which the contact tube (34) is articulated rotatably, the drive lever (50) and the contact tube (34) forming between them, at least in the disconnection position, an obtuse angle which opens in the direction of connection, and in that between the contact tube (34) and the drive lever (50) there is a locking plate (54) which fixes the angular position of the drive lever (50) relative to the contact tube (34) and which releases it towards the end of the connection movement, so that, when the drive shaft (52) is rotated the contact tube (34) forms with the drive lever (50) and the locking plate (54) a rigid unit which, towards the end of the switching movement, is released in such a way that, when the drive shaft (52) and the drive lever (50) are rotated further into the end position, the centre axis of the drive lever (50) can be brought in line with the centre axis of the contact tube (34).
