Embodiment
Below in conjunction with accompanying drawing the utility model being done one describes in detail.
A kind of key switch, referring to Fig. 1～4,11,12,13, the key switch of present embodiment is the two control key switches with universal functor.Key switch mainly is made up of fixed mount, functor, panel and button.Fixed mount 4 is middle rectangular-shaped framework bodies that are provided with through hole, and fixed mount through hole internal fixation has functor, and the fixed mount front is connected with panel 1, and the button 2 that is fixed on the panel is connected with functor by transition piece 31.Functor includes pressing plate 32, back seat 37 and be installed in seesaw in the back seat and inlet wire, outlet binding post.
Back seat is a groove shape body, its cavity is equipped with outlet terminal I 35 and outlet terminal II 36 on one side, outlet terminal I and outlet terminal II center fixed have seesaw 33, the cavity another side middle part of back seat just is provided with the input terminal 34 that is connected with seesaw with the position of seesaw correspondence, the back seat adjacent with input terminal is provided with the through hole 371 that passes for lead for one jiao, described through hole is other to be provided with blind hole 372, and blind hole one side is provided with reference column.Offer through hole and blind hole is convenient to fixedly external wire one jiao of double control switch functor back seat, thus can be so that this double control switch be repacked into the single control switch of band lamp or N end lead.Blind hole also is provided with reference column near a side of outlet terminal.
When pressing button, button acts on the seesaw of functor by transition piece, makes seesaw switch between outlet terminal I and outlet terminal II.When seesaw one end contacts with outlet terminal I, the loop that then is connected with outlet terminal I is connected; When the seesaw other end and outlet terminal II connected, the loop that then is connected with outlet terminal II was connected.
Binding post in the foregoing description, just input terminal and outlet terminal can while crimping fine rule and thick lines.Binding post is made up of screw 81, pressure-ray film 82 and terminal block 83, by screw terminal block and pressure-ray film is screwed onto together.On terminal block and screw nut contact-making surface, be provided with salient point 831.In the process of rotary screw fixing cord, because nut is subjected to the support of single salient point, whole screw can produce inclination, and pressure-ray film also tilts thereupon simultaneously, between pressure-ray film and terminal block, form the triangle gap, thus can be simultaneously fixing 84 two kinds of different leads of thick line 85 and fine rule.
Because terminal block is generally made with brass, hardness is lower, makes the terminal block distortion during use easily, in order to prevent the terminal block distortion, also is provided with reinforcement 832 on terminal block.
Its fixed mount 4 bottom surfaces of the key switch of present embodiment are provided with grid, are installed in simultaneously on the washer 5 of fixed mount bottom surface, functor both sides and also are provided with grid.The grid here is the integrated through injection molding moulding, and stake body bottom surface and washer bottom surface just directly are injection molded into grid surface.Grid surface can be rectangular mesh or circular grid or oval grid or triangular mesh.
It is exquisite more careful that the utility model grid surface on fixed mount and washer sets off out this key switch, makes that the back side of switch and switch front are elegant in appearance equally.
Embodiment 2
A kind of key switch, referring to Fig. 5,6, the key switch of present embodiment is single control key switch of the band LED lamp that repacks on the basis of embodiment 1.
Change the outlet terminal II among the embodiment 1 into process false terminal 361 during repacking by insulating material, simultaneously silver point rivet cancellation corresponding with outlet terminal II on the seesaw is got final product, can connect when just having only seesaw to swing to outlet terminal I, and seesaw does not have when swinging to outlet terminal II the loop to connect yet, and has so just constituted single control structure switch.
At through-hole side column 375 is set, the wiring board 100 of a band LED lamp is fixed in the back seat by column, make LED lamp 101 be serially connected between input terminal and the outlet terminal I.The LED lamp is bright when switch connection, has just constituted single control key switch of band LED lamp.
Embodiment 3
Referring to Fig. 7～9, the key switch of present embodiment is single control key switch of the band neon lamp that repacks on the basis of embodiment 1, is mainly used in the control socket.
Change the outlet terminal II among the embodiment 1 into process false terminal 361 equally by insulating material, simultaneously silver point rivet cancellation corresponding with outlet terminal II on the seesaw is got final product, can connect when just having only seesaw to swing to outlet terminal I, and seesaw does not have when swinging to outlet terminal II the loop to connect yet.One neon lamp 102 is installed in the functor back seat, is connected on the outlet terminal I 35 behind the neon lamp one end series resistor, the other end is connected in series with the N end lead that penetrates back block hole 371 and bend at blind hole 372 places, and neon lamp is fixed on the support column and stop bit post of back seat.Wherein support column 374 and stop bit post 373 are to be located at by the blind hole and the reference column of the setting that is parallel to each other, and are convenient to place neon lamp and be concave arc shape on the support column.
Like this neon lamp be serially connected on the external N end lead, have only input terminal and outlet terminal I be communicated with under the seesaw effect simultaneously neon lamp shinny after, could connect with the socket that external N end lead is connected, so just form the band neon lamp list control key switching structure that to control socket.
Embodiment 4
Referring to Figure 10, the key switch of present embodiment is single control key switch of the N end that repacks on the basis of embodiment 1.
Seesaw one end in the present embodiment in the back seat is corresponding with outlet terminal I, the seesaw other end is corresponding with outlet terminal II, have only a termination corresponding to be provided with silver point on the described seesaw with outlet terminal I, outlet terminal II then repacks N end terminal 362 into, just the silver point rivet of original outlet terminal II repacked into insulating trip 3621, making seesaw not to be communicated with the N end terminal that outlet terminal II repacks into.So just form band N end single control switch, between outlet terminal I and external N end lead, be connected in series indicator light 1021 like that with reference to embodiment 3 certainly, just can form single control key switch of band lamp band N end.Single control key switch of band lamp band N end can be applicable to control switch behind the door with two control Illuminated Switch.
