Embodiment

For reach above-mentioned projects and effect, details are as follows below in conjunction with drawings and Examples, so that those of ordinary skill in the art can implement the utility model.

At first, see also Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, be stereo appearance figure of the present utility model, three-dimensional exploded view, partial schematic diagram and preferred embodiment figure, can know from Fig. 1 and Fig. 2 and point out that rotary switch structure 1 of the present utility model includes:

One pedestal 2, its upper end is formed with a protuberance 21 and an endless groove 23, and the bottom also is provided with a plurality of Lead-through terminals 24, and in addition, protuberance 21 centre positions are provided with an accepting groove 210, and pedestal 2 two outside correspondences respectively are provided with two fixture blocks 22;

One press device 3 is arranged in the protuberance 21 of pedestal 2, and its upper end is provided with at least one illuminating part 31;

One revolving part 4 is sheathed on the protuberance 21 of pedestal 2, and its bottom side outer surface is equipped with a plurality of tooth portion 42, and in addition, the centre position is provided with one and wears groove 41, and the bottom then is provided with a plurality of convex bodys 43;

One conduction element 44, be arranged at revolving part 4 bottoms, its upper end is provided with a plurality of fixing holes 441 and a plurality of contact jaws 442, and conduction element 44 then is the convex body 43 that is incorporated into revolving part 4 bottoms by fixing hole 441, make conduction element 44 can firmly be arranged at revolving part 4 bottoms, see Fig. 3;

One lid 5 is covered on the pedestal 2, and its middle position is provided with an open-work 50, and corresponding each extension of two sides is provided with a positive stop spring plate 51, and respectively is provided with a fixed part 52 in the two side correspondences in addition that are provided with positive stop spring plate 51.

As Fig. 2 and shown in Figure 4, when rotary switch structure 1 uses, mainly be by rotating revolving part 4, make a plurality of Lead-through terminals 24 of conduction element 44 contact pedestals 2 bottoms that are arranged at its bottom, and change the conducting electric current by contacting different Lead-through terminal 24, to reach different conducting effects, and because a plurality of tooth portion 42 of revolving part 4 bottom side outer surfaces is subjected to compressing of positive stop spring plate 51, therefore when revolving part 4 rotates, be the rotating manner of multisection type, and when revolving part 4 is positioned on the different sections, the Lead-through terminal 24 that the conduction element 44 of revolving part 4 bottoms is touched is all inequality, therefore the electric current of institute's conducting also just changes to some extent, and rotary switch structure 1 except can by the illuminating part on the press device 3 31 whether luminous learn open or closing state, revolving part 4 is positioned on the different sections, thereby makes illuminating part 31 produce the variations in light of different brightness.

In addition, lid 5 mainly is two fixture blocks 22 that are snapped in pedestal 2 two outside correspondences by the corresponding set fixed part 52 of its two side, lid 5 firmly is arranged on the pedestal 2, and owing to extended by lid 5 in order to the positive stop spring plate 51 that compresses tooth portion 42, and positive stop spring plate 51 correspondences are positioned at lid 5 two sides, therefore when lid 5 firmly is arranged at pedestal 2, positive stop spring plate 51 is except in order to compress the tooth portion 42, elastic force by positive stop spring plate 51 is compressed by its corresponding two sides, the effect that increases revolving part 4 stability is also arranged, and because positive stop spring plate 51 itself is extended by lid 5, therefore do not need with known shell fragment as the part of making in addition, and must set out the position of putting shell fragment in addition, lid 5 is after being incorporated into pedestal 2, and positive stop spring plate 51 promptly is positioned on the tram that can compress tooth portion 42, and not only positive stop spring plate 51 does not need to make in addition to save outside the cost, also exempt the process time that positive stop spring plate 51 must be set, seen Fig. 2.

Rotary switch structure 1 is except reaching the different conducting effect by rotation mode, also can make the illuminating part 31 of its upper end luminous in the mode of pushing by press device 3, and reach different conducting effects, and the outer transparent outer covers of illuminating part 31 are exposed to the degree difference of revolving part 4 by printing or the processing of thunder carving and illuminating part 31 by different materials, can produce different illumination effects when making illuminating part 31 luminous, in addition, because press device 3 is to install and be positioned to pass through the combination of some glue mode again behind the pedestal 2, therefore if the user only needs the function of rotating, then can not need press device 3 is set in rotary switch structure 1, see Fig. 2 and Fig. 5.

The conduction element 44 of above-mentioned revolving part 4 bottoms and the different Lead-through terminal 24 different conducting effects that produce, as shown in Figure 3, mainly be because conduction element 44 is an annular body, and a plurality of contact jaws 442 set on it are on different circumferential positions, a plurality of Lead-through terminals 24 in design on different circumferential positions, also segmentation is distributed on the diverse location of circumference, therefore, after revolving part 4 is rotating to each section, because the contact jaw 442 of conduction element 44 touches the Lead-through terminal 24 on the diverse location, and the resistance value of each Lead-through terminal 24 is all inequality, promptly causes electric current to change, thereby produces different conducting effects.

The above is preferred embodiment of the present utility model only, is not therefore to limit protection range of the present utility model, and scope of patent protection of the present utility model must be as the criterion with the content of its claims.
