Abstract

A switch includes a handle for activation and deactivation and an actuating device. The actuating device includes a motor drive, which tensions a spring held in a tensioned state by latching by way of a gear. Two spring pairs are provided for activation and deactivation. The two bridges are arranged, with the spring pairs thereof nested within each other and displaceable with respect to each other. The bridges facing each other are pressed apart from one another to tension the spring pairs, and an actuation element is arranged on the one bridge for activation and an actuation element is arranged on the other bridge for deactivation.
