Title: Hybrid electrical switching device

Abstract: The invention relates to a hybrid electrical switching device, comprising an electromechanical relay including a mechanical switching element to be operated by an electrical coil, and a main semiconductor switching element including a control input and a current conduction path which is connected in parallel with the mechanical switching element for energizing an electric load. The main semiconductor switching element is of the type that ceases to conduct when a current through the current conduction path thereof drops below a threshold value. The circuit furthermore comprises an auxiliary semiconductor switching element including a control input and a current conduction path which is connected for controlling the main semiconductor switching element.
