The rotation center of the connecting rod assembly is the central axis of the second boss. The first rib and the fourth rib limit the connecting rod assembly when the switch is in the closed state or the open state. When the main switch changes from the closed state to the open state, the connecting rod assembly rotates 90° clockwise.

[0020] When the switch is in a closed state, the second fillet surface of the connecting rod assembly contacts the first rib and the fourth rib respectively. The first surface and the second surface of the push rod assembly press against the auxiliary contact in the auxiliary switch assembly, so that the auxiliary contact moves inside the auxiliary switch, closing or disconnecting the normally open contact or normally closed contact inside the auxiliary switch, thereby generating a change in the electrical signal, which is then led out from the power terminal.

[0021] When the switch is in the off state, the first fillet surface of the connecting rod assembly contacts the first rib and the fourth rib respectively. The first surface and the second surface of the push rod assembly do not contact the auxiliary contact in the auxiliary switch assembly, and the position of the auxiliary contact does not change, so that the normally open contact or normally closed contact inside the auxiliary switch remains in an open or closed state, the electrical signal does not change, and the electrical signal is led out from the power terminal.

[0022] Compared with the prior art, the utility model has the following advantages:

[0023] (1) The auxiliary contacts are directly hit by the rotating parts inside the mechanism, and the signal transmission is more accurate.
