Abstract: An apparatus for preventing young children from activating a push button switch while allowing adults to activate said button. The apparatus is a semi-rigid child-proof cover or cap for the “home button” or menu button on a personal electronic device or computing tablet. The cap is disposed over the push button switch and prevents young children from pressing it because the strength necessary to bend the semi-rigid material of the cap is beyond that of young children. However, adults have sufficient strength to push the semi-rigid material with enough force that it bends and thus exerts a downward pressure and activates the push button below it. A small hole may also be defined in middle of the cap that allows an adult to use a paperclip or other pointed object to activate the button, while being too small for a young child's finger to pass through and activate the button.
