Touch Light Switch Shuts Off After 10 Seconds - Identical Issue with Replacement

Question

I have touch light switches installed in my apartment (without Wi-Fi function). There was no problem for 10 months, and now the bathroom light switch turns off the light itself 10 seconds after it is turned on. We replaced the switch with a new one and after a week we have the same pattern. Once...

Can you reveal any details about this switch or is it a secret?

Emska91 · Answer

Of course it`s no secret

This is a switch with 1 blue/red illuminated field.
This can says on the back: Voltage 110-220V AC
Load Power: 3-300W/gang
Bought on Allegro at electro24, but came in packaging without a marked manufacturer.

vieleicht · Answer

I think it may be a problem with the switch itself. The voltage range of 110-220V is written on the device and apart from the fact that the voltage in the network is now 230V (it is not without significance), this may mean that the device is old or the capacitors may have dried up. The transition from 22V to 230V took place almost 20 years ago. So maybe these switches are just too old. If they are as old as I think (even if only structurally), then no one thought about controlling LED lighting. I suggest connecting a classic light bulb with several dozen watts and seeing what happens.

Hello, Were there any LED adapters (resistor or capacitor) included with the switch? If so, have they been installed? Regards. PS: Post a photo of the switch and packaging if you have it.

Maybe don`t think so? Because this proves that it is a device from the Far East. Not that it`s 20 years old.... It`s still 220V there.... It`s all the fault of the switch or the method of installation. You may also have a problem with the light source itself. This is a strange switch working without N.

According to the electrician who installed the switches, this yellow square attached to the switch was not needed... To put it simply, could you tell me where it is mounted?

kkknc · Answer

It`s in the diagram. Only needed to prevent the LEDs from glowing.

maurycy123 · Answer

I installed such switches at a friend`s place. This yellow square is a capacitor. It is installed on these switches if the LEDs are of very low power. At least that`s what it said in the manual. Although when it comes to glows, they are also installed. Where is the switch mounted? In the bathroom or outside? Because if it`s in the bathroom, maybe the humidity is harmful to it?

Emska91 · Answer

It is installed in the corridor, so it is not likely to be damp.
And regarding the installation of the capacitor, ok, I understand that there is a diagram, but just for a layman (I won`t install it myself), is it connected somewhere in the black box or somewhere when connecting the lamp?

sk1977 · Answer

Missing a capacitor may be a problem. It is mounted next to the lamp - as close to the bulb as possible (of course, without exaggeration, it can be in the box, at the connection, etc.).

bhtom · Answer

Hello, Unfortunately, you are wrong, and not only this... If so, install it as he mentioned @sk1977 . It certainly won`t make things worse. Additionally, you need to make sure that the sensor (detecting finger touch) under the glass panel does not touch it. Regards.

kkknc · Answer

I don`t think I read the original description on the manufacturer`s website. The LED can light up without it. And at low power, the switch itself, i.e. a small 3-5W LED, may not work properly. But it also depends on the design of the power supply.

sk1977 · Answer

Do you know Chinese? :) From my practical experience - CHR manufacturers` websites write differently and there are often significant discrepancies from reality. I have 4 similar ones, without N, without capacitors, after a while they hung up, stopped responding, after a reset they worked properly again, and hung up again, etc. After installing the capacitors, the problems disappeared.

kkknc · Answer

There is no such language as Chinese. So no one can know.

sk1977 · Answer

- okay, Mandarin, called Standard Chinese, the official language of the People`s Republic of China. You know?

kkknc · Answer

Well, now correct. Of course I know. I finally have Google Translate. 😝 More serious companies write in EN. And they do it well.

Zdzisław1980 · Answer

There used to be a similar problem with dimmers from the Polish GOVENA.
During the connection, it was important that the phase was supplied to the switch (and also to the L terminal).
When neutral was applied to the switch, the dimmer behaved similarly.
It turned on but couldn`t be turned off.
Somehow it reminded me of your problem.
Unfortunately, correcting this situation involved digging into the installation boxes.

sk1977 · Answer

and their products and packaging have their logo - in this type of switches there is often only a piece of paper with illegible instructions (I assume it is an instruction).

SUCHY_666 · Answer

I install such switches throughout the house, and in two places I have a situation where the light goes crazy - it could be described as the operation of a turn signal in a car. The capacitors are installed correctly. Do you know what causes this behavior?

Hello, Does it behave the same with the front glass casing removed? What is connected as load? Regards.

SUCHY_666 · Answer

It also behaves this way without the glass, and the LED ADAPTER is connected

78db78 · Answer

Connect the LED bulb and see the effect.

SUCHY_666 · Answer

Well, this is what happens with gu10 5.5W LED bulbs

bhtom · Answer

Hello, I understand that this is some kind of power supply for LED strips...? Maybe the load is too small and that`s why it`s going crazy. Good idea. Alternatively, replace it with a properly working one and then check. How many of these bulbs are in one circuit? Regards.

SUCHY_666 · Answer

It is a circuit powering three 230V bulbs on the ceiling, and the LED adapter is something like a capacitor designed to eliminate the slight blinking of LEDs. I replace it with a working one and the effect is always the same. A regular analog switch works normally.

dprzyb · Answer

The effect is the same, i.e. the one that worked correctly before is now going crazy, and the one that was going crazy is working properly in another circuit?

bhtom · Answer

Hello, Well, it would be really strange if it didn`t work... ;) In the circuits in which the switches work, are there the same number of bulbs and the same ones, or maybe more? Regards.

SUCHY_666 · Answer

exactly! Added after 49 : About the same, maybe one bulb difference

bhtom · Answer

Hello,

Then test the one missing bulb and check. If it is OK, it means that the load is probably too small for this type of switch. You can try connecting a high-power resistor in parallel with the capacitor already used.

Regards.
