Abstract (en)
[origin: EP0663675A1] The multiple pole medium and high voltage switch has an interrupt unit (10, 12, 14) for each pole. These units (10, 12, 14) each have a drive shaft (30), a movable contact element (18) and a transition rod (38) connecting the contact (18) to the drive shaft (30). A drive handle (40, 56) sits on the parallel drive shafts (30). The handles (40, 56) are connected to a drive (50) common to all the interrupt units (10, 12, 14) via a drive rod (51). The transition rods (38) of all the interrupt units (10, 12, 14) are identical. The drive rod (51) has couplings (44, 46) arranged between the handles (40, 56). The handle arms (40`, 58.58`) have different rotary bearings relative to the drive shafts.
