ABSTRACT:
A drive mechanism for driving a rotary signalling switch of a high voltage electrical apparatus, in particular a disconnector or a grounding switch, the mechanism connecting the rotary shaft of the signalling switch to a rotary actuator shaft of an actuator mechanism for actuating the contacts of the apparatus so that the contacts of the signalling switch are opened or closed when the contacts of the apparatus are opened or closed, the actuator shaft being displaced at an angular velocity .omega..sub.ht during an operation to open or close the contacts of the apparatus. The drive mechanism constitutes a positive action mechanism connected between said drive shaft and said rotary shaft, and includes drive device for driving the rotary shaft of the signalling switch at the beginning and at the end of an operation at a velocity .omega..sub.cs greater than .omega..sub.ht.
