A protective guard for use with a wall-mounted light switch in order to keep the light switch in the desired "on" or "off" state. The guard is a pivotal arm having at one end an opening for receiving one of the mounting screws of the light switch, by which the guard is pivotally connected to the wall plate of the light switch. When it is desired to allow access to and operation of the light switch, the guard is pivoted out of the way. The same general principle of the invention applies to a guard for selectively closing off a wall plug outlet.
