Abstract

A lamp switch with an indicating lamp comprises a housing, the upper portion of the housing is provided with a light emitting diode (LED) configured to indicate a position of a switch, the lower portion of the housing is provided with a photoresistor (RP), the middle portion of the housing is provided with a button configured to control the on-off of a lamp, and the housing is internally providedwith a shunt resistor R; the LED, the RP and the shunt resistor R are electrically connected and are supplied by a 220V alternating current; and the LED is connected with the photoresistor (RP) in parallel. The lamp switch with an indicating lamp is reasonable in design, simple in structure and convenient and rapid in operation, the LED performs luminescence to indicate users to easily find the position of the switch in a dark environment and the LED is in a switch-off state in the daytime, and therefore, the lamp switch with the indicating lamp is convenient to use, simple in manufacturing and low in cost and can be popularized and used.

With the development of science and technology and economy, various switches are born in due course, which is convenient for everyone's life. But what most people use is still the button switch on the ordinary wall, which is economical and easy to use. While this kind of switch brings convenience to everyone, it also has certain disadvantages. For example, when you go home at night, you need to fumble to turn on the light when you enter the door, or you can’t see the position of the switch when you go to another room. Many switches in use now have fluorescent strips, but such fluorescent strips cannot emit light when they are in the dark for a long time. Contents of the invention [00...
