Abstract

The switch has a fixed contact (4) with smaller dimension and electrically connected to a movable contact that has curved arms (2, 3) forming a branch. The contact (4) is engaged between a pair of fingers (21, 31), in closing position of the switch. A clevis and a spacer are connected to ends of the arms to permit lever effect that amplifies electro-dynamic pinch-off exerted on the contact (4) by the fingers.
