Abstract: A movable contact for a rotary switch is provided. The movable contact includes first and second contacts for contacting a stationary contact, where the first and second contacts are arranged at a distance from each other for receiving the stationary contact between the first and second contacts. The first contact is a straight contact blade for contacting stationary contacts at both ends of the blade. The second contact is a spring element configured to bend when the stationary contact is placed between the first contact and the second contact, and to cause a pressing force to the stationary contact to press the stationary contact against the first contact after the stationary contact has been placed between the first contact and the second contact.

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.
