【Detailed ways】

Please refer to FIG. 1 , the switch device combination of the present invention includes a button 10 , a switch 20 and a casing 30 .

The button 10 has a cross-shaped main body 11 formed by two cross beams 12 and 13 intersecting each other. The two free ends of the beam 11 are respectively provided with a first pressing portion 14 with a circular boss 142 and a second pressing portion 16 with a circular boss 162, and the end of the first pressing portion 14 is bent vertically backward. A limiting arm 18 is produced; the two free ends of the crossbeam 12 are bent downward respectively and then stretch out a clamping arm 15 with a barb 17 at the end. Go out a supporting column 19.

The switch 20 is a cuboid, the lower end of which is provided with a plurality of terminals to connect with other components and transmit signals. The switch 20 has a support surface 24 which can support the support column 19 of the button 10. A first pressing portion 21 that can be pressed by the first pressing portion 14 of the button 10 and a second pressing portion 22 that can be pressed by the second pressing portion 16 of the button 10 are protruded from the ends respectively. 21 and the second pressing part 22 can realize the on or off of the corresponding internal passage; The arm 18 cooperates; the switch 20 is provided with a hooking surface 25 parallel to the supporting surface 24 and at a certain distance apart, for hooking by the barb of the locking arm 15 of the button 10 .

The housing 30 has a first opening 32 and a second opening 34 for receiving the boss 142 of the first pressing part 14 of the button 10 and the boss 162 of the second pressing part 16 respectively, and the inner diameter of the first opening 32 Slightly larger than the outer diameter of the boss 142 , the inner diameter of the second opening 34 is slightly larger than the outer diameter of the boss 162 .

Please refer to FIG. 2 and FIG. 3, press the support column 19 of the button 10 against the support surface 24 of the switch 20, and make the first pressing part 14 and the second pressing part 16 of the button 10 respectively align with the first contact of the switch 20. The pressing part 21 and the second pressing part 22, the two clamping arms 15 of the button 10 are hooked on both sides of the hooking surface 25 of the switch 20 by means of its barbs 17, and the limit arm 18 of the button 10 leans against the limit of the switch 20. The bit surface 23 can prevent the button 10 from sliding down from the switch 20, and finally the combination of the button 10 and the switch 20 is installed on the casing 30, and the boss 142 of the first pressing part 14 of the button 10 and the second pressing part 16 The protrusions 162 are respectively accommodated in the corresponding first opening 32 and the second opening 34 of the housing 30 . Press the first pressing part 14 or the second pressing part 16, and the first pressing part 14 or the second pressing part 16 is bent and deflected downward with the supporting columns 19 on both sides of the beam 12 as the fulcrum under the pressing force, so that it is compatible with the switch 20 The first pressing part 21 or the second pressing part 22 is in contact with the first pressing part 21 or the second pressing part 22, and then the switch 20 is operated. The contact of the first pressing part 21 or the second pressing part 22 will gradually return to the original state, thereby completing the reset action of the switch 20 .

In addition, the button 10 of the present invention can also be designed without the locking arm 15 . When assembling, the switch 20 is fixed on other parts (not shown), and the support column 19 of the button 10 is pushed against the support surface 24 by its support surface 24, so that the button 10 is close to the inner surface of the shell 30, and the boss 10 of the button 10 142 , 162 are respectively accommodated and limited in the corresponding first opening 32 and second opening 34 of the casing 30 , so the button 10 can be held. Press the first pressing part 14 or the second pressing part 16 to make it contact with the first pressing part 21 or the second pressing part 22 of the switch 20, and then make the switch 20 work, after releasing the pressing force, the first pressing part 14 or The second pressing portion 16 is restored to its original shape by the elastic force of the beam 11 , thereby completing the reset action.
