[0021] The switch assembly II 3 includes a knob 301, a signal baffle 302, a signal slot 303 and an inductor 304. The knob 301 is a side wall of the upper frame body 101. The signal baffle 302 is equidistantly arranged on two concentric rings in the inner cavity of the upper frame body 101. The signal slot 303 and the inductor 304 are fixedly arranged on the circuit board 5 on the lower frame body 102.

The button 201 and the knob 301 are an integral structure.

[0022] In the specific implementation process, first, the press switch is described: in use, the button is lightly touched, that is, the center position of the frame body is lightly touched. Since the inner wall of the upper frame body is in contact with the annular transmission member II, the annular transmission member II is displaced downward when the upper frame body is stressed. Since the side wall of the annular transmission member II is a strip-shaped clamping groove II, the clamping buckle II plays a guiding role in the displacement process of the strip-shaped clamping groove II, which ensures that the annular transmission member II is vertically displaced downward. At the same time, the sliding buckle I and the sliding buckle II provided on the annular transmission member II press the side walls of the sliding groove I and the sliding groove II. Since at least one end of the sliding groove I and the sliding groove II is a slope, the sliding buckle I and the sliding buckle II are closer to the bottom of the slope of the sliding groove I and the sliding groove II when the annular transmission member II is closer to the annular transmission member I downward, which pushes the annular transmission member I to rotate. The rotating distance of the annular transmission member I does not exceed the rotating arc length of the clamping buckle I of the lower frame in the arc-shaped clamping groove I on the annular transmission member I. When rotating to the maximum position, the point contact switch is in contact with the point contactor provided on the circuit board to realize the control function. At the same time, the return spring is also compressed at the bottom of the baffle of the lower frame. When the button is released, the return spring pushes the baffle to rotate in the opposite direction, thereby driving the annular transmission member I to rotate in the opposite direction, pushing the sliding buckle I and the sliding buckle II to slide on the slope of the sliding groove I and the sliding groove II. At this time, under the action of the pushing force, the sliding buckle I and the sliding buckle II are closer to the top of the slope of the sliding groove I and the sliding groove II, that is, the annular transmission member I and the annular transmission member II are gradually away from each other, thereby driving the button to return to the original position. At this time, the press switch action is completed. The circuit is programmed to set the specific reaction action after the point contact, thereby realizing the control.

[0023] Then for the rotating switch is described: use, rotate the knob, two equidistant arrangement signal baffle will slide in the signal slot, due to the function of the inductor is to induct the signal baffle in the signal slot direction of travel, so as to determine the knob is clockwise rotation or counterclockwise rotation, by setting clockwise rotation action and counterclockwise rotation action corresponding control signal program, thus realizing rotation control, it is worth noting that the ball and arc groove design, the role of the ball is to guide the sliding, more smooth rotation, the purpose of using the groove structure is to make the rotation process more damping, prevent rotation excessive, improve user experience.

[0024] Compared with the prior art, the utility model has the advantages of high space utilization, compact overall structure, multi-dimensional control action, improved product application range, and mechanical transmission structure between overall structural members, sensitive response and reduced failure rate.

[0025] Finally, it is necessary to point out that: the above examples are only used to further detail the technical solutions of the utility model, and cannot be understood as limiting the protection scope of the utility model. Some non-essential improvements and adjustments made by the skilled in the art based on the above content of the utility model belong to the protection scope of the utility model.
