Abstract

The utility model discloses a shift switch, which especially comprises a button, a push rod and a shift mechanism, wherein the bottom of the button is provided with two operation pins arranged side by side, and the bottom of each operation pin is respectively provided with poking shifts and staggered inclined planes on bottoms of two poking shifts. The push rods are in butt joint with the operation pins one to one, and move in the height direction. The shift mechanism comprises a touch control unit and a PCB, wherein the touch control unit comprises two contact springs and a pedestal, and the central eccentric section of the contact spring abuts against the push rod. The pedestal is provided with contact points corresponding to each contact of contact spring. As the position of the push rod changes, the relative contacts are respectively contacted with each other or separated from each other, and the shift switch has an adjusting scope of two shifts on two directions. The shift switch employs bi-row operation pins with poking shift, and has a plurality of sets of switch shifts. The shift switch increases practicality and improves operation accuracy. The shift switch employs an independent touch control unit, and has certain dustproof and waterproof effects.

Description

There is following problem in this structure: this class formation is everlasting and is applied grease as lubricant between pcb board and contact flat spring, but in the situation that temperature reduces, may occur the situation that function as lubricant is lost, and severe patient contact flat spring is firmly pasted on pcb board.This class formation need to make it reply initial condition by parts such as springs, and therefore corresponding cost of manufacture is higher, and the configuration switches of folk art term position also can not meet people's life requirement.

Summary of the invention

In view of the defect that above-mentioned prior art exists, the purpose of this utility model is to propose a kind of driving switch, solves the problem that in prior art, switch gear is less and operation is comparatively inconvenient.

The purpose of this utility model: a kind of driving switch, especially, comprise button, push rod and gear mechanism, wherein button bottom is provided with two operation pin side by side, described in each, operate the inclined-plane of sequence each other, bottom surface that sole end is respectively equipped with fork shift and two fork shifts, described push rod be two and one to one with operation pin dock respectively, push rod is at short transverse top offset, described gear mechanism is comprised of touch control unit and pcb board, touch control unit comprises two contact flat springs and base, push rod of each butt of the stage casing eccentric part of two contact flat springs, one of them contact flat spring is provided with the first contact and San contact, another contact flat spring is provided with Wu contact and Qi contact, relative second contact that is provided with, each contact of described base and contact flat spring, Si contact, Liu contact and Ba contact, the first contact and the second contact on the different height and position of push rod, San contact and Si contact, Wu contact and Liu contact, Qi contact contacts respectively with Ba contact or is separated, described driving switch has each adjustable range of two grades on both direction.

Further, the bottom surface of described fork shift is side-looking Cheng“ factory " inclined-plane of font or indent arc, the bottom surface of two fork shifts misplaces mutually.

Further, described push rod and touch control unit outside are provided with shell, and shell is provided with LED installing hole.

Apply driving switch of the present utility model, adopt the double operation pin with fork shift, there are many group switch gears, increased the practicality of switch, also improved the accuracy of operation, and driving switch adopts independently touch control unit simultaneously, can play the effect of certain dustproof and waterproof.

Embodiment

The problem that the utility model is less for switch gear in prior art and operation is comparatively inconvenient, innovation has proposed a kind of driving switch, adopts the double operation pin with fork shift, has many group switch gears, has increased the Practical Performance of switch.

As shown in Fig. 2 ~ 7, a kind of driving switch, especially, comprise button 1, push rod and gear mechanism, wherein button bottom is provided with two operation pin 11 and operation pin 12 side by side, and each operation sole end is respectively equipped with fork shift 111 and fork shift 112, and the inclined-plane of sequence each other, the bottom surface of two fork shifts, push rod is two, be respectively push rod 21 and push rod 22, and dock respectively with operation pin one to one, push rod 21 docks with operation pin 11, push rod 22 docks with operation pin 12, and push rod is at short transverse top offset, gear mechanism is comprised of touch control unit and pcb board 5, touch control unit comprises contact flat spring 31, contact flat spring 32 and base 33, contact flat spring 31 stage casing eccentric part butt push rod 21, contact flat spring 32 stage casing eccentric part butt push rod 22, wherein contact flat spring 31 is provided with the first contact A and San contact C, contact flat spring 32 is provided with Wu contact E and Qi contact G, the relative second contact B that is provided with in each contact of base 33 and contact flat spring, Si contact D, Liu contact F and Ba contact H, the first contact A and the second contact B on the different height and position of push rod, San contact C and Si contact D, Wu contact E and Liu contact F, Qi contact G contacts respectively with Ba contact H or is separated, driving switch has each adjustable range of two grades on both direction.

Wherein, as shown in Figure 2, the bottom surface of this fork shift is side-looking Cheng“ factory " font, inclined-plane that can certainly indent arc, fork shift 11 bottom surface and fork shift 12 bottom surface misplace mutually.

As shown in Figure 4, for optimizing this driving switch, push rod and touch control unit outside are provided with shell 4, and shell 4 is provided with LED installing hole 41.

During concrete enforcement, driving switch as shown in Figures 5 to 7, first, driving switch in released state, is then once pressed button in initial condition ，Ge contact, make button be as shown in Figure 6 α angle, the fork shift 111 of operation Jiao11 bottom surface compresses push rod 21, and push rod 21 generation displacements make to move to the first contact A under contact flat spring 31 1 side direction and contact with the second contact B, and this is the first gear; Then on the basis of once pressing, carry out secondary and press button, make button be as shown in Figure 7 β angle, push rod 21 produces larger displacement moves downward contact flat spring 31 integral body, and now the first contact A contacts with the second contact B, San contact C contacts with Si contact D, and this is the second gear.In addition, driving switch once lifts two gears that button and secondary lift button lifting also to have in push-button, button principle is identical with pressing, while once lifting button, Wu contact E contacts with Liu contact F, and this is third gear, when secondary lifts button, Wu contact E contacts with Liu contact F, and Qi contact G contacts with Ba contact H, and this is fourth speed position.

By above-mentioned character express, can find out, apply driving switch of the present utility model, employing is with the double operation pin of fork shift, there are many group switch gears, increased the practicality of switch, also improved the accuracy of operation, and driving switch adopts independently touch control unit simultaneously, can play the effect of certain dustproof and waterproof.
