A switch with LED or neon lighting is far from uncommon in homes. The use of such switches is quite practical. At night, you do not have to search the wall with your hand to find the switch. With the advent of LED and CFL lamps, big problems began to arise. In particular, most modern LED lamps blink when the switch is off. Today we will figure out how to turn off the backlight on the switch.
This effect occurs due to the closed electrical circuit formed by the resistor with the LED (or neon lamp) and the power converter circuit of the LED and CFL lamp. In this article, we will consider the simplest method on the question: how to turn off the backlight in the switch.

Disassembled switch with LED inside
Initially, we need to dismantle the switch. Disconnect from the conductors by first disconnecting the switch from the electricity. For those who have already done this more than once, it's a "trivial" occupation.
After the switch is dismantled, it is necessary to remove the casing where the LED itself (or neon) is located.
In our case, the backlight consists of a neon lamp and a 150kΩ resistor. Nothing changes drastically with an LED, so the principle: how to turn off the backlight in a switch with an LED remains the same. The neon lamp is connected through a resistor to the switch terminals.

If you quickly throw in the backlight connection diagram in the switch? then it will look like this:
How to turn off the backlight on the switch: step 2
To correct the situation with us, we need to replace the resistor. In our case, we take a 220 kΩ resistor and a 1 N 4007 diode. The diode can be removed from an energy-saving lamp, where it is used as a diode bridge. The circuit of the converted switch will look like this:
If we leave the neon lamp, then a 220 kΩ resistor will suffice. If we want to change the indicator to a 3 mm diode, then select a 680 kΩ resistor. This is guaranteed to save you from flashing the diode lamp in the chandelier.
How to turn off video switch light
And finally, watch the video again on how to turn off the LED or neon backlight from the switch so that the lamps do not blink. This is a fundamental solution to the problem. We just bite out all the radio components and don't "worry" anymore. However, this way of dealing with blinking does not satisfy me, so it's better to still use the above example. And the switch does not need to be turned into a simple key and the functions remain.
