Abstract
The utility model provides a lightening indicator switch. A lightening indicator circuit composed of an electronic lightening element and a depressurization electronic element is connected to the base of an original switch in parallel. An original switch structure is changed, the manufacture is simple, and the cost is low. When an electrical appliance is energized to use, the electronic lightening element does not indicate, and inversely, the electronic lightening element lightens to indicate. Thus, the lightening indicator switch can clear indicate the positioning point of the switch at the dark places with the electronic lightening element, and the utility model is practical and convenient.
Description
The utility model provides a kind of luminous indicator cock, belongs to the electronic switch field.
At present, existing report about luminous indicator cock, the most employing of its technical scheme is parallel with electronic light-emitting component at the two ends of switch, as Chinese patent communique disclosed utility model patent on October 9th, 1991: display switch, the patent No.: 91204838, contain lid, push-button switch, light-emitting diode, resistance, binding post and box body, the push-button switch hole is arranged on lid, light-emitting diode is housed in push-button switch, light-emitting diode and resistance are formed the switch display circuit, its two ends can be in parallel with push-button switch, also can termination push-button switches, and the unsettled or ground connection of the other end.Use this switch, can accurately judge the switch position after entering the room night, be applicable to various push-button switches or lighting devices such as desk lamp, wall lamp, defective is a complex structure, the cost height.
The purpose of this utility model provide a kind of simple in structure, cost is low, can be used for the luminous indicator cock of indicator cock position at night.
The purpose of this utility model is achieved in that on the basis of original switch, is parallel with the luminous indicating circuit of being made up of electronic light-emitting component and electronic pressure element.
The utility model compared with prior art realizing under the prerequisite of same purpose, and is simple in structure, cost is low.
Fig. 1 is the circuit diagram that the utility model adopts decompression capacitor and light-emitting diode embodiment;
The utility model is described in further detail to engage accompanying drawing below:
After decompression capacitor C and the light-emitting diode D series connection, be connected in parallel on the two ends of K switch again.Like this, when K switch was closed, electric current was from the K switch process, and light-emitting diode D is not luminous, and when K switch disconnected, electric current was supplied with light-emitting diode D, the luminous indication of light-emitting diode D through decompression capacitor C.
Decompression capacitor also can be dropping resistor or other electronic pressure element, and light-emitting diode also can be other illuminating electronic element.
Claims (1)
1, a kind of luminous indicator cock is made up of switch, electronic pressure element and electronic light-emitting component, it is characterized in that: after electronic pressure element and the electronic light-emitting component series connection, again with switch in parallel.
