Abstract
A housing is supported in front of a conventional female wall socket by a conventional two-prong male plug that extends out the rear of the housing and engages the socket. A flag is pivotally secured to the housing and can be pivoted into or out of it in a vertical plane parallel to the wall socket. Normally the flag is retained in the housing. When there is an interruption in the supply of electric power to the socket, the flag will pivot out of the housing automatically.
