Actuating mechanism of a rotary switch with contacts, comprising a mounting base (1) in which an actuating rod assembly (2) and a rotary plate assembly (3) for manual rotation are arranged, wherein an energy storage element (4) is provided between the actuating rod assembly (2) and the rotary plate assembly (3), wherein the rotary plate assembly (3) closes or opens the rotary switch by forward or backward rotation, wherein, when the actuating rod assembly (2) is rotated, the energy storage element (4) rotates the rotary plate assembly (3), wherein a limiting element (5) is pivotally mounted in the mounting base (1), wherein the limiting element (5) has a pressure section (501) and a locking section (502), wherein the rotary plate assembly (3) interacts with the pressure section (501) so that the limiting element (5) can be rotated relative to the mounting base (1) between a first position and a second position, wherein,When the rotary plate assembly (3) is in the closed position, the rotary plate assembly (3) abuts the pressure section (501), so that the limiting element (5) is in the first position, wherein the locking section (502) is on the rotation path of the actuating rod assembly (2) or the energy storage element (4) to lock the rotation of the actuating rod assembly (2) in the case of welded contacts of the rotary switch, wherein when the rotary plate assembly (3) is in the open position, the rotary plate assembly (3) releases the pressure section (501), wherein the limiting element (5) is in the second position, so that the locking section (502) releases the actuating rod assembly (2).
