ABSTRACT:
Each interrupter unit (10, 12, 14) of the switch for medium voltage and high voltage has a drive shaft (30), a moving switch contact piece (18) and a transmission linkage (38) which connects the switch contact piece (18) to the drive shaft (30). All the interrupter units (10, 12, 14) are of identical construction. A drive lever (40) is seated in a rotationally fixed manner on each drive shaft (30), which drive levers (40) are connected to one another via connecting rods (44, 46). In order to bring about staggered switching, the drive levers (40) of at least two interrupter units (10, 12, 14) are arranged in a different rotation position with respect to their drive shafts (30).
