Abstract
Abstract A timer assembly is designed to operate an outside light normally operated by a toggle switch inside a residence. The assembly includes a plug casing having first and second sets of plug blades, the second set of plug blades being designed to receive normal power for the timer within the casing and one side of the first set of plug blades being connected to an outlet side of the timer. The arrangement is such that a double receptacle wall plate incorporating the outside light toggle switch can have one of its electrical outlets rewired so that when the first set of blades of the plug casing are received therein, the toggle switch will be by-passed by the timer for the time interval of its operation to thereby automatically energize the outside light.
