Abstract
A method and apparatus for autonomously switching off a domestic appliance after completion of a previously selected program is disclosed. The domestic appliance has a control device that executes programs controlling the domestic appliance and an operating unit. The domestic appliance is connected to electrical energy from a power source through circuit arrangement comprising a terminal connection and first and second switches. The first electrical switch is separate from the second switch and can be switched from an open state to a closed state in which the switch is electrically conductive to connect the control device to the electrical energy. The control device is designed to switch the second switch from an open state to a closed state in which the control device is connected to electrical energy through the second switch as soon as the first switch is switched to the closed switching state.
