Abstract
To improve the possibilities of using a fast-action switch with positive opening, of the end-of-travel type, the switch is equipped with a set of compression springs which cause its moving equipment to rock and with a set of compensating springs which allow its operating plunger to move through an additional travel after switching, without damaging interference with a positive opening paddle. The additional travel is increased by placing the compensating springs between a front conducting element and the moving equipment which rocks at the time of switching.
