In addition, above-mentioned switch also has a major defect to demand urgently improving, because the elastic portion other end is second positioning section that is positioned first pin with the clamping relation, but the deflection situation is not exclusively arranged owing to electroconductive elastic sheet has part defective item or assembling unavoidably in assembling process or manufacturing process, therefore in use for some time, cause flexure strip to break away from second positioning section easily, and because of elastic portion too near second pin, therefore easy contact the and form conducting state when elastic portion breaks away from second pin, therefore will output error instruct, for high-accuracy industry, once baffled instruction generation will cause the related influence of whole system and cause very big loss.
For this reason, the application once proposed the improvement (No. the 10/085405th, U. S. application) of this kind switch, as shown in Figure 2, a kind of switch that has only half height of above-mentioned switch and reduce thickness not significantly mainly is provided, mainly be that kink with electroconductive elastic sheet changes into to loam cake and extends bending, allow elastic portion to loam cake extend with the button configured in parallel in same interval, to omit original retaining space, in addition, even elastic portion breaks away from second positioning section accidentally, elastic portion will be to top offset, and can not form conducting by false touch second pin, also provide the control purpose of right instructions output, and the base of this switch is that the one ejaculation extends to form out a reinforcement section to loam cake, also the thickness of loam cake and base can be dwindled, and the intensity of global switch will be do not influenced by this reinforcement section.
Though above-mentioned switch can effectively solve the integral thickness problem, when the electrostatic discharge testing, because button and loam cake have the space, so the test value of gained can't effectively promote, and button still has the possibility of loam cake when being subjected to the electroconductive elastic sheet elastic returning.
The utility model content
Main purpose of the present utility model, be to address the aforementioned drawbacks, for avoiding the existence of this defective, the utility model forms a lifting space by first positioning section and second positioning section of this first pin, the through-hole aperture that makes loam cake is less than the lifting space width, make this button possess a forced section that is positioned at through hole again, one is positioned at lifting space and the width stopper section greater than through-hole aperture, an and compression part that is positioned at lifting space crimping electroconductive elastic sheet, thereby when making switch carry out static discharge, protection test value (ESD) can be subjected to the stopper section and separate and obtain higher value, and design because of this stopper section, can make button when being subjected to the electroconductive elastic sheet elastic returning, be difficult for deviating from and obtain effective location.
