Abstract
A pushbutton and an electrical switch can be linked to one another so that movement of the pushbutton, for example by a user depressing the pushbutton, can control the switch. The switch can be in a closed position prior to being depressed and in an open position afterwards, or vice versa. A photodetector can be located on the switch side of the pushbutton. The pushbutton can be formed of a material that transmits light so that light can pass through the pushbutton for receipt by the photodetector. The pushbutton can additionally or alternatively be formed with an opening that is sized to receive an object inserted by a user. Insertion of the object can manipulate a second electrical switch, which may control flow of electricity from a battery, for example.
