[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Example

[0036] See Figures 1 to 4As shown, a spring-type dial knob switch comprises a circular switch seat 1, the inner ring edge of the circular switch seat is integrally formed with a convex ring 2, and a knob structure 3 is arranged on the circular switch seat. In this embodiment, the convex ring is mainly used for rotation limit of the knob structure to prevent loosening or shaking during rotation; and the circular switch seat is an insulating plastic structure, and in actual application, the knob structure comprises a limit ring 31 and a knob body 32; the limit ring is mainly used for limiting the knob body to prevent it from loosening or falling off, so as to ensure the stability and effectiveness of the installation of the knob body.

[0037] In addition, a dial structure 4 is fixed on the top surface of the convex ring, and a toggle structure 5 is positioned on the bottom surface of the knob body; a plurality of locking holes 6 are arranged on the outer wall of the convex ring, and a locking convex point 7 is fixed on the inner wall of the limit ring; during assembly, the knob body can be rotatably arranged in the limit ring, and the limit ring is sleeved on the convex ring and is positioned in the locking hole through the locking convex point; the toggle structure can jump and abut against the top surface of the dial structure. Through the above structure, the efficiency and stability of assembly can be improved, and the dial structure and the toggle structure cooperate to realize the control of dial jumping.

[0038] In actual application, the dial structure includes a central ring 41 and two semicircular dial pieces 42; and a plurality of pressing protrusions 43 are integrally formed on the inner wall of the semicircular dial piece; when combined, the two semicircular dial pieces are symmetrically arranged on the outer side of the central ring, and a gap is arranged between the pressing protrusion and the outer ring edge of the central ring; a gap is arranged between the two ends of the two semicircular dial pieces. The central ring and the semicircular dial piece are located on the top surface of the annular switch seat, and there is a gap between the central ring and the semicircular dial piece, so that the two will not be short-circuited, and the gap between the pressing protrusion and the adjacent pressing protrusion is matched, so that when the toggle structure is toggled, it can jump in the gap between the pressing protrusion and the adjacent pressing protrusion to achieve conduction and disconnection jumping.

[0039] Moreover, in actual application, the ends of the central ring and the two semicircular dial pieces are both provided with conductive plugs 8; when connected for use, the connection polarities of the two semicircular dial pieces are the same, that is, the signal jump can be realized by staggered conduction or disconnection of the two semicircular dial pieces to realize the encoding function, which is highly practical.
