| Jan 2, 2022 at 23:55 | comment | added | jcaron | How is a “button powered at 220V”? A button does not use any power (or an extremely small amount). A button just opens or closes a circuit, which in the simplest case would be between your local reference voltage (usually 3.3V or 5V) or ground and a GPIO pin (details vary depending on the type of button). If there’s 220V somewhere around, there’s more than just a button… please provide a schematic of the circuit which includes this button. | |
