摘要（英）：

The invention relates to a knob switch which comprises a base, a lantern ring fixed on the base and a rotator limited between the base and the lantern ring. The knob switch also comprises a first contact body positioned on the rotator, a second contact body positioned on the lantern ring, a first pull-in element, a second pull-in element and a third pull-in element. The first pull-in element and the second pull-in element are positioned on one of the rotator and the lantern ring, the third pull-in element is positioned on the other one of the rotator and the lantern ring, the rotator can rotate relative to the lantern ring to make the first pull-in element or the second pull-in element pull in the third pull-in element, resulting in that the first contact body and the second contact body are in a contact state or a separate state to generate corresponding presetting commands.
