Child proof my onan generator button — any suggestions?

Hey Guys — So for whatever reason in my rage’n toy hauler.. they put the generator button low enough to where a kid can reach it.. (my 1 yr old sees the orange light and thinks oooo let me push that button). As much as I can yell at him till he’s old enough to understand.. I’d prefer to put some sort of cover over it.. any suggestions ?

I looked for thermostat covers..but the ones i’ve found are just too big… I’m ok even swapping for a different switch altogether that would work too..

thanks in advance
