Description

Flower shape key swich

The utility model relates to a kind of electric control switch, particularly the multikey switch.

At present, the multikey switch of use mostly is in-line and arranges, and is difficult for during operation differentiating, and is easy to generate misoperation and has an accident.

The purpose of this utility model is to avoid above-mentioned weak point among the background technology and the easy note that provides a kind of button to be flower-shaped arrangement is easily differentiated, be difficult for the generation misoperation and avoid the easy to operate of accident generation, safe and reliable, and show the colored shape key swich of figure beauty outward can for the people.

The purpose of this utility model realizes by following approach: housing is connected with cover plate, a plurality of buttons are flower-shaped arrangement around the center button, the card of falling T passes cover plate and is connected with the center button, L type card passes the corresponding connection with button of cover plate, pocketed springs on button and the center button, via pins location and installation circle is buckled in the housing inner chamber, the housing intracavity bottom is by the fixing width of cloth bar shell fragment of the central screw that connects power line, on the width of cloth bar shell fragment base torsion spring that fuses is arranged, the corresponding width of cloth bar of housing bottom shell fragment is fixed with the screw that connects control line.

Colored shape key swich of the present utility model, circle are buckled the barb draw-in groove of control L type card motion, cooperate the draw-in groove of the card motion of falling T, the location notch of control circle button rotation amplitude and the torsion spring jack of plug-in mounting torsion spring.There are vertical slot and L type draw-in groove, housing intracavity bottom with the card of falling T two arm suits that the lattice firebreak is arranged on the housing, installing hole is arranged on the housing.Projection with housing intracavity bottom pit suit location is arranged on the width of cloth bar shell fragment base.

The utility model is compared background technology following advantage: a plurality of buttons are flower-shaped arrangement around the center button, and easily note is easily differentiated, and are difficult for producing the generation that accident is avoided in misoperation, and are easy to operate, safe and reliable, and can give image appearance U.S..

The embodiment of the utility model in conjunction with the accompanying drawings is described in further detail.

As shown in Figure 1 to Figure 3, colored shape key swich of the present utility model, cover plate 4 is connected with housing 6, and L type card 5 passes cover plate 4 and button 2 corresponding connections.Button 2 and L type card 5 are respectively a plurality of of correspondence.The card of falling T 10 passes cover plate Center-to-Center button 1 and connects.Equal pocketed springs 3 on button 2 and the center button 1.Housing 6 intracavity bottoms have lattice firebreak 11 and by the fixing width of cloth bar shell fragment 9 of the central screw 17 that connects power line.Buckle 8 by pin 18 location and installation circles in housing 6 inner chambers, the barb draw-in groove 12 of control L type card 5 and the location notch 20 that the control circle is buckled 8 rotation amplitudes are arranged on the circle button 8.The torsion spring 15 that fuses with width of cloth bar shell fragment 9 bases is inserted in the torsion spring jack 19 that encloses on the button 8.Two arms of the card of falling T 10 and vertical slot 7 suits on the housing 6.The L type draw-in groove 13 corresponding suits of L type card 5 and housing 6 have installing hole 16 on the housing 6.The screw 14 of the connection control line corresponding with the shell fragment of width of cloth bar shell fragment 9 is installed in the bottom of housing 6.When pushing button 2 the time, be that wedging ring is contained in the spring 3 on the button 2, promptly move downward the L type draw-in groove 13 that enters on the housing 6 with the L type card 5 of button 2 corresponding connections, enter corresponding barb draw-in groove 12 on the circle button 8 simultaneously, force 8 dextrorotation of circle button, when L type card 5 puts in place, circle button 8 is left-handed immediately under the effect of torsion spring 15, the barb of barb draw-in groove 12 fastens L type card 5, and the shell fragment of L type card 5 compressing width of cloth bar shell fragments 9 and the corresponding termination contact that is installed in the screw 14 of housing 6 bottoms make circuit turn-on.When pressing another button 2, the corresponding L type card 5 that connects moves downward, and forces 8 dextrorotation of circle button, the button 2 of originally conducting pop into position under the effect of spring 3, and circuit disconnects.Press a plurality of buttons 2 simultaneously, many circuit conductings simultaneously.When pressing

center button

1,10 liang of arms of the card of falling T move downward along the vertical slot on the housing 67, enter the draw-in groove 22 on the circle button 8 simultaneously, force 8 dextrorotation of circle button, each button 2 of conducting under the effect of the spring 3 of suit separately, pop into position simultaneously, and disconnecting.Unclamp hand, center button 1 resets under spring 3 effects of suit immediately.

As shown in Figure 4, colored shape key swich of the present utility model, a plurality of buttons 2 are flower-shaped arrangement around center button 1.

As Fig. 5, shown in Figure 6, colored shape key swich of the present utility model, torsion spring 15 fuses with the base of width of cloth bar shell fragment 9, and width of cloth bar shell fragment 9 is by projection on the base 21 and housing 6 intracavity bottom pit suits location.

As Fig. 7, shown in Figure 3, colored shape key swich of the present utility model, the circle that is installed in housing 6 inner chambers is buckled the barb draw-in groove 12 that control L type card motion is arranged on 8, and the location notch 20 of control circle button 8 rotation amplitudes cooperates the card of falling T to play the draw-in groove 22 of total stopper action and 15 torsion spring jacks 19 of plug-in mounting torsion spring.
