1. A current switch arranged between a first portion of electric line and a second portion of electric line, comprising:
at least one main contact comprising an electrically conductive knife, and an electrically insulating element, the main contact being fitted in a mobile manner on the first portion of electric line in order to alternatively follow:
an opening movement from a closed position in which the main contact is in electrical contact with the second portion of electric line to an open position in which the main contact is distant from the second portion of electric line, and
a closing movement from said open position to said closed position;
at least one shunt branch comprising a first part electrically connected to the second portion of the line, the first part comprising a vacuum interrupter configured to be actuated alternatively between an open state and a closed state, and a second part mounted in a mobile manner on the first part and configured to actuate the vacuum interrupter,
the electrically conductive knife and the electrically insulating element being configured so that:
during the opening movement, the electrically conductive knife acts upon the second part in order to actuate the vacuum interrupter into the open state, and
during the closing movement, the electrically insulating element acts upon the second part without actuating the vacuum interrupter.
