Embodiment

For the ease of those skilled in the art will recognize that the utility model is described in further detail below in conjunction with drawings and Examples.

The disassembled form structure of the utility model embodiment is shown in Fig. 1～3, and assembling back state profile as shown in Figure 4.

As Fig. 1,2,3, the rotary components 2 that rotary switch described in the embodiment comprises cylindrical shape fixation kit 1 and is mounted thereon, what described rotary components 2 comprised the turncap 21 of upper end and lower end revolves post 22, turncap 21 with revolve post 22 and be structure as a whole, one is finished when the die sinking injection moulding.Offer conduit 12 at fixation kit 1 inwall symmetrically along circumferential both sides, fixation kit 1 inside bottom is provided with two fixed-conductive films 13, these two fixed-conductive films 13 are connected with two switch pins 14 respectively, two switch pins 14 and fixed-conductive film 13 are injection-moulded on fixation kit 1 bottom surface together, and two switch pin 14 lower ends pass fixation kit 1.Be symmetrical arranged two overhead structures 221 on rotary components 2 outer walls, the conduit 12 on this structure and the fixation kit 1 is used.During use, two barbs 221 are stuck in respectively in two conduits 12, realize being located by connecting on fixation kit 1 and rotary components 2 are axially; During the switch rotation, barb 221 slides in conduit 12.

Establish a projection 222 in rotary components 2 lower ends, movable conducting strip 23 is strip arc spring laminations, and perforate in the middle of it is riveted on the projection 222 with the hole.

Usually under the state, fixed-conductive film 13 and two pin ones 4 in the fixation kit 1 separate.With rotary components 2 rotations, movable conducting strip 23 also rotates thereupon, when movable conducting strip 23 two ends touch fixed-conductive film 13, two pins is communicated with promptly to be rotated in place be equivalent to the regular tap down state; Opposite spin rotary components 2 makes movable conducting strip 23 break away from fixed-conductive films 13, is equivalent to the regular tap state of upspringing this moment.

For improving operation performance of as switch, when switch was rotated in place, the operator can have tangible feel, and the preferred scheme of the utility model is that correspondence is provided with some elastic devices and position limiting structure on fixation kit 1 and rotary components 2.When rotary components was rotated in place, elastic device and position limiting structure cooperated, and in general elastic device sinks in the position limiting structure.

Be provided with two kinds of spacing fit structures in the present embodiment, as shown in the figure, establish an extension at one of them a end of two fixed-conductive films 13, this extension end is bent to form projection 131 upwards; Described rotary components 2 bottom edge are provided with two limited impressions 28 along fixed intervals; During rotary components 2 rotations, projection 131 is slided between two limited impressions 28 of rotary components 2 bottoms.When rotary components 2 was rotated in place forward or backwards, the projection 131 that fixed-conductive film extension end is bent to form embedded respectively in two grooves 28, made the operator that tangible feel be arranged, and avoided rotating not in place, produced the phenomenon of switch loose contact.

Another kind of position limiting structure is: one side above rotary components 2 sidewalls with groove 28 tiltedly right spacing block set 29 also is set, stopper slot 19 is established at corresponding edge, fixation kit 1 upper end, during rotary components 2 rotations, projection 29 slides in stopper slot 19, when being rotated in place, projection 29 is touched the two ends of stopper slot 19 respectively, makes the operator that obvious feel be arranged.This structure also makes rotary components 2 and fixation kit 1 that cooperation precision more is installed, and operates more reliable.

Certainly these two kinds of position limiting structures can use simultaneously, also can select a use as required; Perhaps when not having these two kinds of position limiting structures, can come the angle rotatable of spacing rotary components 2, use the mode of the termination restriction barb 221 of conduit 12, to increase operating handle by the size of conduit 12.

In the foregoing description, the pair of switches pin only is set on the fixation kit 1, corresponding a pair of fixed-conductive film.In the practical application, can evenly be provided with manyly, then can realize many grades of controls of rotary switch at fixation kit 1 inner bottom part to switch pin and fixed-conductive film.

Rotary components 2 is generally injection molded in the utility model, is the convenience of injection moulding, and rotary components 2 is not entity usually, and inside can be set as the part hollow-core construction, so also can further save cost.For easy to assembly, be respectively equipped with contraposition breach 15 and contraposition breach 25 on fixation kit 1 and the rotary components 2, when the two is fitted together, contraposition breach correspondence, then the internal structure position all can be corresponding, is convenient to assembling.

The utility model actual product diameter can accomplish about 10mm that for easy to operate, the frictional force when the increase people operate also is provided with the point-like projection at turncap 21 upper surfaces.This kind projection can also be pitting or the texture that is formed on the turncap upper surface etc.

In sum, above embodiment only is the preferable embodiment of the utility model, not breaking away under the utility model design prerequisite its any minor variations of doing and being equal to replacement, all should belong to protection range of the present utility model.
