Abstract: A security electrical power interrupt apparatus prevents usage of an electrical appliance such as an electric stove, or other electrically operated device. The apparatus includes a relay controlled by a micro-processor based programmable controller. The device includes a detachable component through which data is input. Data is input to the detachable component through a key pad. A software computer program operates in the controller and causes the relay to disconnect the supply power from the device if any attempt is made to operate the appliance or device in a manner which draws electrical current exceeding a preset limit while the controller is in an interrupt mode.

Abstract: A security electrical interrupt device for preventing unauthorized usage of an electrical appliance such as an electric stove, while retaining operation of auxiliary electrical equipment such as the lights and an electrical clock. The device comprises a relay controlled by a micro-processor based programmable controller which measures the amount of electrical supply current being drawn by the appliance. A software computer program stored in the microcontroller commands the relay to disconnect the supply power if any person attempts to operate any part of the appliance which draws electrical current exceeding a preset limit while the controller is in the interrupt mode. In a preferred embodiment the microcontroller is programmed to enter the interrupt mode by 1) key sequences entered on a detachable key pad, 2) when a selected amount of time has elapsed since the last authorized usage, or 3) by removal of the detachable key pad.

The micro controller is programmed to enter the interrupt mode by 1) key sequences entered on a small detachable keypad, 2) when a programmed amount of time has elapsed since the last authorized usage, or 3) by removal of the detachable key pad.
