Description

Glass lifter switch

Technical field

The present invention relates to a kind of automobile and use switch, relate in particular to a kind of glass lifter switch.

Background technology

The existing glass lifter switch, employing be four pairs of clapper-type contacts, when connecting corresponding contacts, corresponding glass lifting motor positive and inverse circuit is connected, thereby realizes the up-down of glass.Like the patent No. is Chinese utility model patent " the switch of lifter for vehicle windscreen " (Granted publication number: CN2444805Y) of ZL00232312.5; The inner contact break-make structure that adopts the spring chip of this patent; Product reliability is poor; Fragile, the assembling volume is also bigger, can not satisfy the installation requirement of lifter.

For this reason; The applicant discloses the patent No. that has obtained: (Granted publication number: CN2755762Y), this patent comprises seesaw button, ejector pin, compression spring, pin, base, housing, moving contact contact chip to the Chinese utility model patent " switch of lifter for vehicle windscreen " of ZL200420072779.X, is placed with compression spring in two suspension columns that extend seesaw button bottom; The compression spring bottom is connecting ejector pin; The seesaw button is fastened on housing top, and enclosure interior is placed the moving contact contact chip, and the moving contact contact chip is slideable the contact with ejector pin; Below lower housing portion and the base clamping, base pin is arranged.The seesaw button of borrowing is realized the adjusting of switch.But it is because not satisfactory in this patent to the installation and design of indicator light; Be easy in the assembling process damage; Based on this; The applicant discloses the Chinese utility model patent " a kind of independent switch of lifter for vehicle windscreen " that the patent No. is ZL200920112302.3 again, and (Granted publication number: CN201352520Y), this patent is optimized the layout of lamp socket and indicator light.

Though through for many years improvement design, glass lifter switch sensitivity, assembling agility and functional had many raisings; But still some technical problem needs to solve in the applicant's actual production process: at first; Ejector pin all is to be installed in advance in the button in the present switch, and button needs a special containing cavity of placing ejector pin, makes comparatively inconvenience of moulding; Ejector pin is easy to drop from the ccontaining cavity of button in the assembling process in addition, influences operating efficiency; Secondly, button directly acts on the seesaw movements that ejector pin is realized movable contact spring, and during operation, the button feel is not good enough, and painstaking point is difficult to feel; Once more, owing to be that movable contact spring and static contact close the realization break-make through bat, in the long-term use of this structural design, it is bigger to wear and tear between movable contact spring and the static contact, occurs phenomenons such as loose contact easily, produces loose contact thus; At last, movable contact spring if not assembling at once of ejector pin is easy to displacement outside being exposed to, influences assembly precision after installing on the base.
