摘要

The present invention relates to the control of a switching apparatus comprises two switches, such as a busbar disconnector, and a grounding switch. According to the invention, it is provided: - a control shaft in rotation, - two systems to toggle joint, each comprising two levers articulated together, one of the articulated levers (2210, 2211) being secured to the control shaft (220), and the other (2220, 2221 and 2250, 2251) being connected to one of the movable contacts (200, 210). The mechanism according to the invention makes it possible to obtain the dead point of driving by the alignment of the pivoting axes (222, 223 or 222, 225, or 225, 226) of the levers with the axis of rotation of the control shaft, when each movable contact (200, 210) is in the vicinity of or in its closed position.
