Abstract: An appliance includes an appliance interface forming a plug connection with an appliance-side interface unit of a power cable. The appliance interface includes at least one power contact part forming a power connection with a power contact part of the appliance-side interface unit supplying the appliance with electrical energy from a supply grid. The appliance interface includes a first thermoelectric element contacting a second thermoelectric element of the appliance-side interface unit, when the power connection exists. The first thermoelectric element is coupled to a first measurement input of a control unit. The appliance interface includes a measurement contact part forming a measurement connection, between the second thermoelectric element and a second measurement input of the control unit, with a measurement contact part of the appliance-side interface unit. The control unit determines measurement data relating to a measurement voltage between the first and second measurement inputs.

Abstract: A circuit for operating a household appliance includes a controller that controls processes of a household appliance, a switching power supply that supplies current to the controller, a pushbutton that couples the switching power supply to a supply grid, an electronic controller connected parallel to the pushbutton that is actuable by the switching power supply by a control connection, and a voltage storage connected between the control connection of the electronic controller and a reference potential.

Abstract: A circuit for operating a household appliance, having a switching power supply for transforming a grid voltage of a supply grid to a direct current supply voltage, a controller for controlling processes of the household appliance that can be coupled to the switching power supply and supplied by the DC supply voltage, and a button by means of which the switching power supply can be coupled to the supply grid by closing an electrical switch. The switch has two mechanically stable states and can be transitioned from one mechanically stable state to the other by actuating the button and/or by an at least indirect energy input from the controller.
