    Abstract: A rotation mechanism for a rotary switch and a method of operating a rotary switch are provided. The rotation mechanism includes a mechanism shaft for switching the switch between open and closed positions of the switch, a crank rotationally connected to the mechanism shaft, a spring connected to the crank, where the spring has a dead point between the open and closed positions of the switch, and a force transmission roll rotationally connected to the crank. The mechanism shaft, crank and force transmission roll have a common axis of rotation. There is a predetermined rotational free-play between the rotation of the mechanism shaft and the crank, and a predetermined rotational free-play between the rotation of the crank and the force transmission roll.
