[0026] Reference Figures 1-3 According to the utility model discloses a kind of embodiments of protecting the light touch switch of shell, including base 11, the opening cavity 12 is equipped in the base 11, further include the cover plate 13 for closing the opening cavity 12 on the base 11, in addition, the bottom surface of the opening cavity 12 is equipped with side edge bump 14 and middle bump 15, the side edge bump 14 is equipped with two and respectively at the left and right sides of the middle bump 15, further include the terminal connected to the side edge bump 14 and the middle bump 15 and extended to the outside of the base 11, the side edge bump 14 is equipped with shell 16, and the opening cavity 12 is further equipped with the pressing plate 17 pressed in the middle protruding portion of the shell 16 upper side, the upper end of the pressing plate 17 is equipped with the button 18 penetrating the cover plate 13.

[0027] When the button 18 is pressed, the pressing plate 17 will press the elastic sheet 16 on the middle protrusion 15 to make the side protrusion 14 and the middle protrusion 15 conductive, at this time the switch is turned on, while the button 18 is not pressed, the button 18 will be lifted and reset under the elastic force of the elastic sheet 16.

[0028] In addition, in order to avoid the elastic sheet 16 being damaged and deformed due to the button 18 being pressed by external force during transportation and storage, the edge of the cover plate 13 is integrally formed with a positioning plate 19 extending downward, the side of the opening cavity 12 is provided with a first through slot extending outward, the side of the positioning plate 19 is provided with a second through slot, and the first through slot is provided with an insertion plate 20 which can be inserted into the second through slot, so that the button 18 is not higher than the upper edge of the cover plate 13, thereby avoiding the button 18 being pressed and protecting the elastic sheet 16, and the first through slot, the second through slot and the insertion plate 20 are respectively provided with two groups of left-right symmetrical.

[0029] In the second embodiment of the protection elastic sheet touch switch, in order to facilitate the position control of the insertion plate 20 to avoid the insertion plate 20 being pulled out during transportation and storage, the left and right sides of the pressing plate 17 are respectively provided with spring grooves, the insertion plate 20 is connected to the bottom surface of the spring groove by a spring and extends out of the spring groove, and the insertion plate 20 is further provided with a cutting port 21, and the upper side of the pressing plate 17 is further provided with a top rod 22 which is not higher than the button 18.

[0030] The cutting port 21 is arranged in the lower side of the insertion plate 20, and the cutting port 21 extends through the front and back, and the side of the cutting port 21 close to the spring is an inclined surface which inclines upward and outward.

[0031] The cutting port 21 arranged in this way makes the part of the insertion plate 20 in the spring groove not affect the lifting work of the pressing plate 17 after the insertion plate 20 is disconnected.

[0032] Specific process:

[0033] As Figure 1 As described above, during the storage and transportation of the protection elastic sheet touch switch, the insertion plate 20 extends out of the spring groove and penetrates through the second through hole and the first through hole, at this time the positioning plate 19 is lifted and does not abut against the base 11, and at this time the cutting port 21 is in the first through hole, the insertion plate 20 can limit the positioning plate 19 and the pressing plate 17 to avoid them pressing the elastic sheet 16.

[0034] As Figure 2As shown, when the need to install the one protective spring sheet touch switch, the staff through the sharp object to the inside of the plug 20, until the plug 20 is no longer in the second through hole, the positioning plate 19 is unlocked to be able to move down, the cutting edge 21 is in the inner edge of the first through hole and the open cavity 12.

[0035] As shown, when the cover plate 13 is pressed down until the upper side of the base 11, in the process, the top rod 22 will be pressed down by the cover plate 13 to make the pressing plate 17 sink, at this time the plug 20 will be broken at the cutting edge 21, and part of the plug 20 stays in the first through hole, part of the plug 20 stays in the spring groove, and then the staff can press the button 18 and through the spring sheet 16 to make the switch conduction. Figure 3

[0036] In addition, in order to make the cover plate 13 press on the upper side of the base 11 and no longer be able to reset upward, the upper side of the base 11 is connected with the head 23 through the convex column, and the locking groove is further provided in the cover plate 13 to accommodate the convex column, that is, after the cover plate 13 is pressed on the upper side of the base 11, the head 23 passes through the locking groove and abuts against the upper side of the cover plate 13 to lock the cover plate 13.

[0037] It is necessary to additionally explain that when the button 18 is pressed down, the plug 20 remaining in the first through hole will not move to the open cavity 12, and the left and right sides of the open cavity 12 are respectively polished or painted, so that the friction generated by the plug 20 in the spring groove and the side of the open cavity 12 does not affect the resilience of the spring sheet 16.

[0038] The above is only a specific embodiment of the present application, but the technical features of the present application are not limited to this, any person skilled in the art in the field of the present application, the change or modification is covered in the patent range of the present application.​
