A circuit configuration for operating a household device contains a power supply connector, an electrical load that is connected via a power connection cable to the power supply connector, and a controller for an endangering component. The forming process of a thin film pattern of the invention can be a process of forming a thin film pattern by arranging a functional liquid on a substrate P. A catch deflector extending centrally from the actuator toward the securement tang has a free end configured to displace the catch away from the casing when cause by an operator to move toward the securement tang. In the server device, an encoder compresses and encodes data to be transmitted that includes a double buffer storing the encoded data.
