Embodiment

For reach above-mentioned projects and effect, in this careful collocation accompanying drawing, lift a preferred embodiment, in order to do just in this field tool know that usually the knowledgeable can be with regard to the enforcement according to this of projects.

At first, see also Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, be stereo appearance figure of the present utility model, three-dimensional exploded view, partial schematic diagram and preferred embodiment figure, to shown in Figure 8, the utility model push switch 2 mainly includes as Fig. 3:

Pedestal 3 is provided with accommodation space 30 in it, and respectively is provided with the fixture block 31 of two correspondences on outside two respective side, be provided with terminal board 4 in the accommodation space 30 in addition, and terminal board 4 is provided with at least two Lead-through terminals 41;

Light-emitting device 5 is located in the accommodation space 30 of pedestal 3, is provided with two LED 51 on it at least, and LED can be the specification of blue light, green glow, ruddiness or white light, and is arranged on the light-emitting device 5 with the LED51 collocation of different size;

Housing 6, each extends the fixed part 61 that is provided with to T font body its two corresponding sides, and is sticked on the pedestal 3 by fixed part 61;

Movable pedestal 7 is embedded on the pedestal 3, and its four outer surfaces respectively are provided with at least two fins 7

1 with at least two grooves 72, movable pedestal 7 one sides are provided with conduction element 73, and on the conduction element 73 and be provided with plural shell fragment 731;

Pressing piece 8, for the light-permeable material made, be covered on the movable pedestal 7, four outer surfaces of pressing piece 8 respectively are provided with projection 81, be provided with transparent cover body 9 on the pressing piece 8 in addition, this transparent cover body 9 then by four outer surfaces on it set wear groove 91, covered and be incorporated on the pressing piece 8.
