Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Examples
Referring to fig. 1-3, the present invention provides a technical solution: a novel high-resilience light-touch switch comprises a base 1 and a cover plate 2 arranged at the top end of the base 1, wherein a guide pillar 3 is arranged in the base 1, the top end of the guide pillar 3 is connected with a button 4 extending out of the cover plate 2 in a sliding manner, the guide pillar 3 is connected with a lower partition plate 10 and an upper partition plate 12 in a sliding manner from bottom to top, a conducting sheet 11 is detachably connected between the lower partition plate 10 and the upper partition plate 12, specifically, the conducting sheet 11 is respectively connected with the lower partition plate 10 and the upper partition plate 12 through screws, the outer diameter of the conducting sheet 11 is smaller than that of the upper partition plate 12, the outer diameter of the upper partition plate 12 is smaller than that of the lower partition plate 10, wiring sheets 6 embedded in the base 1 are symmetrically arranged at two sides of the guide pillar 3, both ends of the bottom of the wiring sheets 6 are respectively connected with wiring pins 9 extending out of the base 1, the top end of the wiring sheets 6 is bent downwards to form elastic sheets 7, specifically, the elastic sheets 7 have elasticity along the radial direction of the guide pillar 3, the bottom ends of the elastic sheets 7 are matched with the conducting sheets 11, can be through baffle 10 and the cooperation of last baffle 12 down, carry out the centre gripping to switching on piece 11, and by guide pillar 3 to baffle 10 down, switch on piece 11, go up baffle 12 and button 4 and lead, and then press button 4 to promote switching on piece 11 and go up and down along guide pillar 3, and the top surface contact through 7 bottoms of shell fragment and lower baffle 10, fix a position switching on piece 11, and then contact through shell fragment 7 and switching on piece 11, 6 formation routes of lug plate of intercommunication both sides, after 11 returns of switching on piece, break away from the contact with shell fragment 7 and break off the route.
