ABSTRACT:
A switching assembly for a high voltage switching installation includes a tubular movable main switching contact in which is disposed an auxiliary switching pin. An elastic spring drive with a drive lever and a cocking lever is pivotably attached at an outer part of a shaft traversing the movable main switching contact. The drive lever is connected at an end opposite the pivot shaft to one end of a coupling lever in turn pivotably connected at an end to the auxiliary switching pin by means of a shaft. A hinged spring is connected at one end to the drive lever and at an opposite end to the cocking lever. A guide roller of a mechanical control is rotatably secured to the cocking lever and is disposed in a longitudinal guide slot for controlling the cocking of the spring to shift the drive lever between two end positions.
