Embodiment

Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection range of the present utility model is not subjected to the restriction of embodiment.

As Fig. 1-shown in Figure 5, the utility model multifunction rotary switches comprises: switch loam cake 2, guide post 3 and switch lower cover 6, guide post 3 is the setting of L type, guide post 3 can be around attaching together the central axis rotation of all-in-one-piece switch loam cake 2 with switch lower cover 6 up and down, switch loam cake 2 is provided with the guide post positioning through hole 1 of up/down perforation, the upper end of guide post 3 is located on the guide post positioning through hole 1, the lower end of guide post 3 is provided with and connects screens 7, conductive connecting piece 8 is connected to and connects in the screens 7, the inner of conductive connecting piece 8 is that the rotation place of guide post 3 is provided with second contact 12, be provided with first contact 11 in the outer end of conductive connecting piece 8, be provided with outwardly directed return contact 15 at rotation place, the lower end of guide post 3; Inner surface central authorities at switch lower cover 6 are provided with contact terminal 9, contact terminal 9 is connected with 12 contacts of second contact, the inner surface of switch lower cover 6 is provided with gear terminal jacks 5 in a side of the inswept relevant position of guide post 3 lower ends rotation, be fitted with a plurality of gear terminals 4 in the gear terminal jacks 5, rotation by guide post 3, first contact 11 on the conductive connecting piece 8 can be connected with 4 selective exposures of gear terminal, the inner surface of switch lower cover 6 is provided with return terminal 13 at the opposite side of the inswept relevant position of guide post 3 lower ends rotation, the inner surface of switch lower cover 6 is provided with return stuck point 14, and return stuck point 14 can be adaptive with return contact 15 clampings on the guide post 3; Return contact 15 is made by elastomeric material, and when return contact 15 contacted (it is maximum that the elastic deformation of return contact 15 does not reach) with 14 clampings of return stuck point, first contact 11 was in the no-terminal position between gear terminal 4 and the return terminal 13.

Contact terminal 9, be connected in series as one road circuit of rotary switch with non-essential resistance, gear terminal 4 and return terminal 13 are connected in series as another road circuit of rotary switch with the resistance of outside respectively, and first contact 11 and second contact 12 all are outwards to protrude to be provided with.

As shown in Figure 5, in the application's the multifunction rotary switches, the outer meeting resistance resistance of terminal 51-58 in the gear terminal 4 of setting arranged clockwise reduces successively, therefore the electric current by above-mentioned terminal increases successively, and the outer meeting resistance resistance of return terminal 13 (being terminal 58 ') is big or small identical with terminal 58 outer meeting resistance resistances.When clockwise rotating guide post 3, first contact 11 on the conductive connecting piece 8 on the guide post 3 contacts successively with terminal 51-58 respectively, owing to realized the effect (electric current increases successively) of by-pass cock speed by the electric current difference of terminal; When rotating counterclockwise guide post 3, when first contact 11 of conductive connecting piece 8 is rotated through terminal 51, be rotated further guide post 3, conductive connecting piece 8 on the guide post 3 is connected with 13 contacts of return terminal, because return contact 15 is made by elastomeric material, return contact 15 is in the largest deformation state at this moment, guide post 3 can't continue to rotate counterclockwise, because the outer meeting resistance of terminal 58 ' is identical with the outer meeting resistance resistance of terminal 58, so the time electric current and conductive connecting piece 8 and terminal 58 by switch contact identical when being connected; Unclamp guide post 3 this moment, because the 15 elastically-deformable recoveries of return contact, first contact 11 of conductive connecting piece 8 can clockwise rotate, and stops at the position of no-terminal between terminal 51 and the terminal 58 ' at last.

Those skilled in the art should know that return terminal 13 (being terminal 58 ') can be set the resistance of its outer meeting resistance as required, the setting identical with terminal 58 that is not limited to present embodiment.

More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection range of the present utility model.
