Description

The scalable electric switch

Technical field:

The utility model relates to the electric equipment technical field, refers in particular to a kind of adjustable electric switch.

Background technology:

Switching device is widely used in the various electric equipments, and its operation principle mainly is to utilize the disconnection of contact point or closure to cut off circuit or close and circuit.Present switch has only two kinds of operating states more: close and or disconnection.This single working method can not satisfy people's demand, control some equipment because need in many cases by a switch, and the single switch of structure can't be realized these functions at present, need to add in addition auxiliary electric component, so, complex structure not only, and be difficult to guarantee the safe, reliable of its performance.

Summary of the invention:

The purpose of this utility model is to provide a kind of adjustable electric switch.

The utility model is achieved by the following technical solution: module is rack-mount by the draw-in groove on the support, and module is made of base, end cap, slide block, shell fragment, and end cap is fixed on the base; Shell fragment places in the base, and all there is a salient point centre of every touch article on the shell fragment; Lug plate places the top of shell fragment one end, and is fixed on the end cap; Slide block in the module is pressed on the shell fragment, and its upper end protrudes out the chute of offering on the end cap, and upper end of slide block offers a groove, and its bottom surface offers some grooves.Slide block is fastened on the projection of support inner surface extension by the groove of offering on it; Offer a through hole on the end cap, be provided with a curved surface that rises and falls on support and inner surface that module combines, spring places in the through hole, and a ball is compressed on the curved surface.

After adopting this structure, switch can be by the slip of slide block, make shell fragment respectively with different lug plate conductings, thereby realize control to distinct device.

Embodiment:

See accompanying drawing 1,2,3,4,5,6,7,8, the utility model comprises: support 1 and module 2, module 2 is installed on the support 1.Support 1 one is a circular arc body, is connected with a fluctuating curved surface 11 and a projection 12 along its inner surface center, be provided with in its both sides with module 2 with wide draw-in groove 13.Module 2 is fixed on the support 1 by draw-in groove 13.

Module 2 is made of base 21, end cap 22, slide block 23, shell fragment 24.Base 21 is provided with division board 211, and end cap 22 is fixed on the base 21, and offers a chute 221 on the end cap 22, shell fragment 24 places in the base 21, lug plate 3 is fixed on a side of end cap 22, and an end of lug plate 3 places the top of shell fragment 24 1 ends, and the other end extends end cap 2.Slide blocks 23 in the module 2 are pressed on the shell fragment 24, and it slides by chute 221, offer a groove 231 on the slide block 23, offer a through hole 222 on the end cap 22; The projection 12 that support 1 inner surface extends just in time places in the groove of offering on the slide block 23 231, and spring 25 places in the through hole 212, and a ball 26 is compressed on the curved surface 11.

Shell fragment 24 be " " shape, every touch article 241 places respectively in the space of being cut apart by division board 211, and all there is an arcuation salient point 2411 centre of every touch article 241, a touch article 241 of each lug plate 3 corresponding shell fragment 24.Every touch article 241 middle salient points 2411 distribute point-blank on the shell fragment 24.

The bottom surface of slide block 23 offers some grooves 232, and its position is interlaced.When using the utility model, the salient point 2411 on the touch article 241 will alternately fall in the groove 231.

When using the utility model, at first the utility model is connected in the required circuit, wherein shell fragment 24 links to each other with lead away from an end of lug plate 3, and each lug plate 3 links to each other with lead respectively, and shell fragment 24 is not connected with lug plate 3 under slide block 23 pressure effects.3 of three wiring and touch article 241 are arranged in the present embodiment.Promote support 1 in use, make it to produce relative displacement with module 2, support 1 is when moving, and slide block 23 is sliding in chute 211 under the drive of projection 12.Ball 26 will roll along fluctuating curved surface 11 when support 1 slides, and the pressure that utilizes spring 25 to produce makes whole device can be in metastable state when stopping to slide.When slide block 23 slides into certain position, the salient point 2411 on the touch article 241 will fall in the groove of offering slide block 23 bottom surfaces 232, and this root touch article will upwards lift, and its tail end will contact with lug plate 3, make line conduction.Continue to promote support 1, slide block 23 continues to move, and the salient point 2411 on the every touch article 241 will be fallen in the groove of offering slide block 23 bottom surfaces 231, and touch article will upwards be lifted, and with corresponding lug plate 3 conductings, so form a kind of switching device as shown in Figure 9.

The utility model can be by the slip of slide block 23, and respectively with different lug plate 3 conductings, thereby realization is to the control of distinct device.
