Abstract:
1. A circuit for operating a household appliance comprising: a switching power supply for transforming a grid voltage of a supply grid into a direct current supply voltage; a controller for controlling processes of the household appliance, which is coupled to the switching power supply and is able to be supplied with the direct current supply voltage; and a button for coupling the switching power supply to the supply grid by closing an electrical switch that has two mechanically-stable states, the switch being transitionable from one mechanically-stable state into another mechanically-stable state by actuating the button and/or by an indirect supply of energy from the controller, wherein the electrical switch has a first controller connected in series with the button, wherein the electrical switch comprise a latching relay and a triac is connected in parallel to the button that is able to be activated by the controller.
