ABSTRACT:
An operating mechanism of a three-position switch comprises a tumbler device with an energy storage spring associated with a toggle, a main operating crank controlled by a switching shaft, and an earthing crank mounted in rotation on a first operating spindle. Opening and closing are performed by means of a second operating spindle, offset from the operating shaft and operating in conjunction with a transmission system designed to drive the toggle. A latching lever of the main crank is unlocked by a boss when the toggle is in the vicinity of the dead-point.
