Optimized current switch on power line

A current switch arranged between a first power line segment and a second power line segment, comprising:

• a first switch element comprising a main contact and a secondary contact rigidly connected to the main contact, mounted so as to be mobile on the first power line segment so as to follow a separating travel between a closed position and an open position, the main contact being arranged so as to:
• be in electrical contact with the second power line segment when said first switch element is between said closed position and an intermediate opening state between said closed position and said open position,
• no longer be in electrical contact with the second power line segment when said first switch element is between said intermediate opening state and said open position;
• and
• a second switch element mounted so as to be mobile on the second power line segment and forced towards a rest position by elastic loading;
• wherein the secondary contact of the first switch element is designed to:
• cooperate with the second switch element so as to move the second switch element against said elastic loading in a first portion of said separating travel from the closed position to a release state between said intermediate opening state and said open position,
• not interfere with the second switch element in a second portion of said separating travel between said release state and the open position, so that the second switch element is then brought back to the rest position by said elastic loading;
• and wherein the second switch element and the secondary contact of the first switch element are arranged between two panels made of insulating material.
