SWITCH

摘要

The invention relates to a rotation mechanism for a rotary switch comprising a mechanism shaft (7) for switching the switch between open and closed positions of the switch, a crank (51) rotationally connected to the mechanism shaft (7), a spring (45) connected to the crank (51), wherein the spring (45) has a dead point between the open and closed positions of the switch, a force transmission roll (46) rotationally connected to the crank (51), wherein the mechanism shaft (7), crank (51) and force transmission roll (46) have a common axis of rotation, and wherein there is a predetermined rotational free-play between the rotation of the mechanism shaft (7) and the crank (51), and a predetermined rotational free-play between the rotation of the crank (51) and the force transmission roll (46).
