Circuit arrangement for connecting or disconnecting the electrical components of a domestic appliance to/from a mains power supply (L, N), comprising - a switching-mode power supply for providing at least one DC supply voltage (Ugl2, Ugl3), - an operating handle, which, when actuated, can cause switching-on or switching-off by a user, - at least one control means that can signal events, the control means being at least indirectly connected to a DC voltage output of the switching-mode power supply such that energy can be supplied to said control means, - an electrical switch (3, K1) for coupling the switching-mode power supply to the mains (L, N), which switch can cause the switching-mode power supply to couple to or disconnect from the mains by means of the operating handle and the control means, and - at least one energy store (2, 11) for storing electrical energy in the form of an electrical charge, the control means being designed to generate a voltage and/or current pulse for the electrical switch (3, K1) from the stored electrical energy in order to cause the switching-mode power supply to couple to or disconnection from the mains (L, N), a first energy store being provided for providing the electrical energy required for switching the electrical switch (3, K1), and a downstream, additional energy store being provided for supplying energy to the control means, which additional energy store is able to supply energy to the control means when the switching-mode power supply is disconnected from the mains (L, N), characterised by a priority circuit, which is designed to charge the first energy store with a limited, maximum charging current as a priority and, after a predetermined charging state is reached, to charge the additional energy store for the control means with a limited charging current when the switching-mode power supply is disconnected from the supply network (L, N). - a switching-mode power supply for providing at least one DC supply voltage (Ugl2, Ugl3), - an operating handle, which, when actuated, can cause switching-on or switching-off by a user, - at least one control means that can signal events, the control means being at least indirectly connected to a DC voltage output of the switching-mode power supply such that energy can be supplied to said control means, - an electrical switch (3, K1) for coupling the switching-mode power supply to the mains (L, N), which switch can cause the switching-mode power supply to couple to or disconnect from the mains by means of the operating handle and the control means, and - at least one energy store (2, 11) for storing electrical energy in the form of an electrical charge, the control means being designed to generate a voltage and/or current pulse for the electrical switch (3, K1) from the stored electrical energy in order to cause the switching-mode power supply to couple to or disconnection from the mains (L, N), a first energy store being provided for providing the electrical energy required for switching the electrical switch (3, K1), and a downstream, additional energy store being provided for supplying energy to the control means, which additional energy store is able to supply energy to the control means when the switching-mode power supply is disconnected from the mains (L, N),
