Abstract
A switchgear apparatus having at least one movable contact biased in an open position by an opening spring, a loading mechanism of a closing spring and a kinematic opening and closing system linking the closing spring, the movable contact and the opening spring. The system is controlled by an opening latch and a closing latch. A closing order can be validly transmitted only to the closing latch when the apparatus is in a 'ready to close' state, i.e. open, loaded and without a permanent opening order. The switchgear apparatus has an indicator with three positions: a 'not loaded' position, a 'ready to close' position, and a third 'loaded and not ready to close' or 'loaded disengaged' position. The indicator is kinematically linked to the loading mechanism, the opening latch, and the movable contact.
