I can’t seem to understand the engineering behind non-push buttons. Take for example my coffee maker. I tap my finger on the top of it and it turns on, but theres no physical button, just the power symbol. I figured this would be more fun than asking google.

Non-push buttons, also known as capacitive touch buttons, work by detecting changes in electrical capacitance. When you touch the surface of the button, you change the electrical field around it, and the button’s circuitry detects that change. This then triggers the desired action, such as turning on your coffee maker.
