1.18in Dia Emergency Stop Button Cover Lockout,2 Pack Round

These worked out great for our front load washer. We use a small carabiner clip so the grandson can’t press buttons

Unfortunately this locking cover has a huge design flaw for use with an estop button. Estop buttons are designed to kill the power in an emergency and normally have a big mushroom shape. You need a lock so that people won't reenergize the circuit while you are working on it. When you push an estop button it latches and can only be unlatched if you pull the button back out and twist it. If you have a 30 mm estop button with the cover open you could mash it down and latch it. The power would be off. You could close the cover and lock it out. But now when your want to restore power you open the cover back up and you will not be able to unlock it? You must be able to get your fingers around it to pull it and twist it to unlock it and energize the circuit. The button would need to have a diameter of 15mm in order to get your fingers around the button to pull and twist it and that defeats the purpose of a "big red button." So this is not a cover for an estop button as advertised. However I am giving it two stars because you could put a conventional latching button in the cover, it would work because you don't need to pull the button out, you just push it a second time.
