Abstract
Abstract A control comprising a securable case having an internal outlet into which a TV set may be plugged with the TV set plug secured within the case. ON and OFF pushbuttons are provided. When the ON button is depressed, the TV set may be operated for up to a predetermined total time. During this time, an accumulator wheel driven by a timing motor through a clutch rotates up to a predetermined angular position. When this position is attained, the internal outlet of the device is disconnected from the power line. When the OFF button is depressed, the outlet is not supplied with power and the accumulator wheel is not driven by the timing motor. Each 24 hours a reset wheel upon attaining a predetermined angular position causes the accumulator wheel to be reset to its initial position.
