Abstract
A perpendicularly-opening grounding section switch comprising a female contact and a male contact disposed at the end of the drive rod includes two parallel metal horns disposed in such a manner as to clamp against the end of the arm in the vicinity of the male contact when the section switch is in the closed position, and a flexible metal rod or whip which is constrained to slide along a fixed point of a guide piece while the arm is performing an opening operation, the respective lengths of the horns and of the whip being selected so that current is switched first to the horns and then to the whip during an opening operation.
