Abstract: The present invention relates to a hand blender having a processing tool for mixing or comminuting foodstuffs. The hand blender has an electric motor, a power source with a first pole electrically connected to the electric motor and a second pole electrically connected to the electric motor, a controller, first and second mechanical switches having a first position and a second position, an electromechanical element for detecting the position of the first mechanical switch, and an electrical switch for detecting the position of the second mechanical switch.

Abstract: The present invention relates to a domestic appliance with a power source being electrically connectable to an electrical motor for driving a processing tool, the domestic appliance comprising a first mechanical switch being manually switchable from a first position into a second position, a second mechanical switch being manually switchable from a first position into a second position, an electronic safety system with first means for detecting the position of the first mechanical switch and second means for detecting the position of the second mechanical switch, the electronic safety system being constructed such that the motor is only connected to one or both poles of the power source if both mechanical switches are switched into their second position and if the first mechanical switch is switched into its second position before the second mechanical switch is switched into its second position.
