When aforementioned existing Switch main body uses, be to select to depress each gear button 46, the gear depression bar 44 that cooperates is pressed into location in the Switch main body 10, so that electric equipment products such as electric fan or smoke exhaust produce different rotating speeds, in the time will stopping the electric equipment products running, then be depress stop key 45 with its below stop depression bar 43, the gear depression bar 44 that is positioned after interlock release presses down whereby, the spring 47 that is sheathed on this gear depression bar 44 this moment can make the gear button 46 and gear depression bar 44 homings that originally were pressed down with top on the gear button 46 on its top.

Though existing Switch main body can reach the effect of control apparatus product, yet 45 to indicate with the function of gear button 46 all be directly to be printed on the panel of electric equipment products owing to stop key, therefore at insufficient light or do not have under the operating position of light illumination, can produce the situation that is difficult to identification key position and function and produce, be unfavorable for user's operation.

[utility model content]

Because existing electric switch lacks luminous sign, therefore the environment in insufficient light or dark can produce the problem that is difficult for the identification operation.For this reason, the utility model main purpose is, is provided with LED in the button of light-permeable, and is provided with the shinny structure of triggering LED in the button below, provides button shinny effect with this, makes the operation of user's easy identification.

For achieving the above object, the utility model provides the switch of tool LED lamp in a kind of button, and it comprises:

One Switch main body, it is provided with a switch base, between the end face and bottom surface of this switch base, stop perforation and the perforation of several gears along laterally wearing one with form at interval, vertically plug one in this top that stops to bore a hole and stop depression bar, vertically plug a gear depression bar respectively in the top of each gear perforation again, in the bottom surface of this Switch main body in conjunction with a top bracing member, its below in this Switch main body is provided with a base plate, place a spring respectively in this bottom that stops to bore a hole with each gear perforation, each spring is resisted against this base plate with the bottom, is socketed on the bottom of this bottom that stops depression bar or each gear depression bar again with the top;

One LED triggers element, its in this switch base end face in conjunction with a circuit board, stop towards this in this circuit board by the side in the depression bar outside, by this stops the side in the outside of depression bar gear depression bar farthest, and the position between the adjacent two gear depression bars is stretched respectively and is established an electroconductive elastic sheet; And

One LED key groups, it stops key in the top upper shield one that this stops depression bar, this light-permeable that stops key, and the left side of its root edge, right both sides are positioned at the top of contiguous two electroconductive elastic sheets, again in the top of each gear depression bar difference upper shield one gear button, each gear button light-permeable, and the left side of root edge, right both sides lay respectively at the top of contiguous two electroconductive elastic sheets, in stopping key top with each gear button, this respectively is provided with a LED, the left side of each LED, right both sides are extended two electrodes down, extend down and hook stops key or the left side of each gear button root edge in this with two electrodes, right both sides.

Further, switch base described in the utility model is a rectangle and along the housing of horizontal expansion, described base plate is a shape to plate body that should the switch base bottom surface, this base plate is convexly equipped with a projection up in the end face at both ends, with two projections against and screw lock be incorporated into the bottom surface location of this switch base, corresponding describedly stop to bore a hole and the below of each gear perforation, be convexly equipped with a spring inserted link respectively up in the end face of this base plate, the bottom of described each spring is to be socketed on each spring inserted link.

Further, the corresponding described position that stops to bore a hole with several gear perforation of the utility model, front end in described switch base is provided with several wire terminals, the part that described each electroconductive elastic sheet stretches out described circuit board is unsettled form, offers a kerf again in the middle of the outer end of each electroconductive elastic sheet of position between adjacent two gear depression bars inwardly.

Preferable, the described end face that stops key with each gear button forms an operation respectively and indicates.

Preferable, the utility model circuit board is the plate body along horizontal expansion, and is incorporated into the front side of described Switch main body end face.

Be to be located in the electric equipment products such as electric fan, baking box, smoke exhaust, fruit juice mixer when the utility model uses, to stop key and each gear button protrudes from the shell of electric equipment products, with the mode of pushing each gear button of the utility model can the control apparatus product startup and the speed of rotating speed select.

When selecting to depress wherein a gear button, it can press down beneath gear depression bar and locate, the electrode that press down gear button root edge both sides this moment can contact contiguous electroconductive elastic sheet, therefore can the conducting electric current and make LED produce the light that outwards appears, in dim, provide clearly identification means of user with light.

Closing power supply of the present utility model and order when depressing the gear button of location, back and upspringing when needs, is to depress the interlock that stops key to stop depression bar and press down, and the gear depression bar that has pressed down the location this moment can be released upsprings and stop luminous.And in the process of pressing down that stops key, when the electrode of its root edge both sides touches two contiguous electroconductive elastic sheets, also can send the light that is available for users to identification mark by LED.

Since the utility model stop key and each gear button in be provided with can be shinny after pressing down the LED structure, even therefore make the adusk environment of the utility model use, the means of user's easy identification key position or function also can be provided with shinny button, reach the effect that makes things convenient for user's identification operation.
