Easy to wipe true, but what if instead of a capacitor button we can have a magnetic control board with magnetic push keys?

It would be fully removable, attachment magnet snaps it into place and then it's essentially a button with a magnet physically travelling up and down.

The I really hate the capacitor buttons since if you get pasta that boils over it fucks with the buttons pretty fast and the "off button" is just not good for quickly turning it off when flooded. It's same for pan cooking sauce that splashes a bit, wiping the surface moist rag can have mixed results, paper towels become a requirement. There's just a lot to not like.

A standard knob, as long as it's not designed by an idiot, can be very simple by having a piece of heat resistant non corrosive material stuck out of the stove top and the button having a 1cm gap under it. Just make the pin chonky and you can drop a pan on it without anything happening. Lift the button off and it becomes still very easy to clean.
