An electric food mixer includes a membrane potentiometer control which is responsive to a user\s touch to select the speed of the mixer\s motor. The top surface of the membrane potentiometer control is flexible and forms a continuous strip which is mounted flush with the mixer motor\s housing so as to facilitate cleaning and improve the appearance of the mixer. The top surface of the membrane potentiometer control may include a flexible liquid crystal display to provide to the user visual feedback of the selected motor speed. A digital control is responsive to the output of the membrane potentiometer control for operating the mixer\s motor at a mixer motor speed selected in accordance with the membrane potentiometer\s output from a large number of selectable mixer motor speeds stored in a look up table in the digital control.
