<p>The invention relates to the control of an electric switching apparatus that includes two switches such as a busbar sectionalising switch and an earthing switch. The invention comprises: a rotation control shaft; two toggle members each including two levers hinged together, one of the hinged levers (2210, 2211) being connected to the control shaft (220) and the other (2220, 2221 or 2250, 2251) being connected to one of the mobile contacts (200, 210). The mechanism of the invention makes it possible to obtain a driving neutral point by aligning the pivot axes (222, 223 or 222, 225 or 225, 226) of the levers with the rotation axis of the control shaft when each mobile contact (200, 210) is close to or in the closed position thereof.</p> |
