Abstract
The utility model discloses a lighting button wall switch which has the lighting and displaying functions at the position of the pressing point of the opening terminal of the press-button. The lighting button wall switch mainly solves the problems that the existing wall switch can not directly display the accurate position of the press-button in the dark and the neon tube of the existing switch with the lighting and displaying functions has single lighting color, unbright color and short service life. Because the lighting component of the switch adopts the luminous diode and the utility model has the advantages of small size, long service life, convenient installation and operation and bright color, the lighting button wall switch is convenient to popularize.
Description
The utility model relates to and a kind ofly is added with luminous demonstration on the press points that button is opened, and can check power supply whether electricity is arranged, and consuming device opens and closes and the switch on wall of consuming device quality function.
Existing switch on wall does not have the luminous Presentation Function of button, open electric light or other consuming device in the dark, be difficult for by arriving shift knob, though the switch that has has luminous Presentation Function, but since luminescent device all be mounted in shift knob above or below, the direct press points of display switch, so use still inconveniently in the dark, used luminescent device all adopts neon tube.Because the neon tube volume is bigger, so be difficult for being installed on the button of switch, the glow color of neon tube is single in addition, cost is high, useful life is not long, so reduced the technology and the economy of switch.
The purpose of this utility model be to provide a kind of have at button open its position of luminous demonstration on the position of press points and can check power supply whether to have electricity, consuming device to open and close and the novel wall wall switch of consuming device quality function.The luminescent device of this switch can be selected versicolor light-emitting diodes such as reddish yellow Bai Lv for use, so it is bright in luster, the life-span long, overcome the deficiency of neon tube.Outstanding feature of this switch is that luminescent device directly is installed on the unlatching pressing position of button, when turning on light or opening other consuming device night, needn't seek or grope shift knob, as long as finger presses can be opened consuming device on luminous point.Simultaneously, also can be by the light-emitting diode luminous quality of checking consuming device whether.
The utility model is achieved in that common button switch on wall is installed additional a Light-Emitting Diode illuminating circuit.This circuit is formed by connecting by resistance, diode and light-emitting diode, two vacant after connecting ends is even pressed with two binding posts of switch respectively get final product.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
(K) is appliance switch among the figure; (1) is the movable contact spring of switch; (2) be the current-limiting resistance of illuminating circuit; (3) be rectifier diode; (4) be light-emitting diode.When power supply has electricity, (press the button and open an end) during with switch (K) closure, electric current flows into electrical appliance through (K), and electrical appliance begins work done, and illuminating circuit two ends warps this moment (K) link to each other, and form equipotential (its current potential is zero), so light-emitting diode is not luminous.When switch (K) disconnected, electrical appliance stopped work done, and electric current forms the loop through current-limiting resistance, rectifier diode, light-emitting diode, electrical appliance and lead, so lumination of light emitting diode.Because the current-limiting resistance resistance is very big, its operating current is minimum during illuminating circuit work, does not work so electrical appliance is similar to.The switch main body of this switch is identical with original switch on wall, just the opening end at switch ship shape button leaves or makes a call to hole, a garden, the aperture is slightly larger than the light-emitting diodes external diameter of pipe, then light-emitting diode is packed into forward in the button hole by the button rear portion, treat that LED top is fixing with concordant back, button outside, the pin of light-emitting diode is flexible coupling with flexible cord and other part, resistance, diode all are welded on the fritter circuit board, this circuit board is fixed on the suitable location of switch the inside, and the two-terminal of switch and circuit are connected firmly gets final product then.When pressing switch open one end, light-emitting diode extinguishes, the electrical appliance work done.When shift knob turn-offed, electrical appliance stopped work done, and Light-Emitting Diode is luminous, and is not luminous as light-emitting diode, confirming that power supply has electricity, proves that then electrical appliance might damage or loose contact.
Because this closing and beautiful appearance, compact conformation, volume are small and exquisite, minimal power consumption, life-span are long and easy to install, so very easy to utilize.
Claims (2)
1, a kind of switch on wall with luminous Presentation Function on button unlatching press points position is characterized in that:
One small garden hole is arranged on the position of the opening end of A, described shift knob, and light-emitting diode (4) is installed in the hole, garden, and the pin of light-emitting diode is flexible coupling with flexible cord and other part.
B, current-limiting resistance (2), rectifier diode (3) is connected with light-emitting diode (4), is connected with two terminals of switch respectively connecting two vacant ends of back.
2, switch according to claim 1, its light-emitting diode (4) can be selected shades of colours such as reddish yellow Bai Lv for use.
