[embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
As Figure 1-3, a kind of rotary switch without connecting axle, comprise the outer knob 2 and the inner button 3 that are separately positioned on guidance panel 1 both sides, outer knob 2 is corresponding with inner button 3 positions, be provided with between described outer knob 2 and the described inner button 3 described outer knob 2 and described inner button 3 are fixed magnetic assembly 4 on guidance panel 1, and so that when described outer knob 2 rotation, described inner button 3 can be along with described outer knob 2 synchronous rotaries.Be connected with the encoder 5 of control circuit at inner button 3, thereby this encoder 5 detects the angular displacement of knob along with inner button 3 synchronous rotaries.
Described magnetic assembly 4 is separately positioned on the bottom surface of outer knob 2 and the bottom surface of inner button 3, and the bottom surface of the bottom surface of outer knob 2 and inner button 3 is relative along the both sides of guidance panel 1.Described magnetic assembly 4 is magnet and magnet, and two magnet magnetic poles are inhaled mutually, and a magnet is embedded on the bottom surface of outer knob 2, and another magnet is embedded on the bottom surface of inner button 3, and relative magnetic pole produces suction on the contrary; This magnetic assembly 4 also can be magnet and ironware, and magnet is identical with the shape size of ironware, and magnet is arranged on outer knob 2 or the inner button 3, and ironware is arranged on inner button 3 or the outer knob 2, mutually produces suction.
