Abstract
A rotary switch structure includes a sleeve, a seat body, an elastic ring, plural push elements and a fixing element. The seat body is accommodated within the sleeve. The elastic ring is disposed on the seat body. The plural push elements are disposed on the elastic ring, and provide a pushing force to the elastic ring. The fixing element is fixed in the sleeve and contacted with the plural push elements. The plural push elements are fixed on the elastic ring by the fixing element. The elastic ring absorbs the pushing force, so that a friction force between the at least one push element and the elastic ring is adjustable. Consequently, the rotating feel of the rotary switch structure is adjustable according to the practical requirements.
