Good afternoon.
I have recently purchased a smart light switch mounted instead of the standard mechanical switch in the wall. It is a popular touch switch with the ability to connect to the Tuya app.
It has two connection options. One using zero working N and the other option does not require this connection, but it is then necessary to place a capacitor in parallel with the current consumer. I know that there are also versions that do not require a capacitor, but I happen to have one.
The problem is that everything works as it should, but when the lamp is switched on, the capacitor makes a sound like a fly. It is the kind of buzzing sound that most people will probably recognise. From what I've read this is normal as due to the alternating current inside the capacitor the film electrodes (if that's the correct term?) vibrate slightly. Some people have written that by using a capacitor from other companies e.g. Nichicon the problem disappears. Unfortunately I cannot find a capacitor from this company with the right parameters. So my question is whether there is any possibility of solving this problem, or is it just a matter of replacing the switch with one that does not require a capacitor? Perhaps there is a possibility to modify this switch to work without a capacitor? Maybe someone can help and knows the solution.
Capacitor parameters: 3.3uF 275V X2
I should add that I have also tried to replace this capacitor with another one purchased locally from an electronics shop. To be precise, for two with capacitances of 1.5uF which together gives a value close to the original one, i.e. 3uF. Capacitor class X2, of course. Voltage 305V AC. Unfortunately the problem is exactly the same.
