Abstract

Abstract Electrically operated appliance controls and methods of making the same are provided, one control comprising an electrically operated device for providing two different functions of the device, an electrically operated visual display unit, and a manually operated selector unit electrically interconnected to the device and the display unit for selecting a desired function of the device and for setting the device to provide that selected function in a desired set manner thereof as being indicated on the display unit by such operation of the selector unit. The selector unit has a manually operated start actuator which when actuated will cause the device to begin to produce the selected function thereof and in that selected set manner thereof. The selector unit comprises a manually operated movable selector member which when moved in one direction a certain amount from an off position thereof to a first position thereof selects one of the functions and then sets the device to provide that selected function in a desired manner as being indicated on the display unit as the selector member is being further moved in the one direction from the first position thereof and which when moved in the other direction a certain amount from the off position thereof to a second position thereof selects the other of the functions and then sets the deviceto provide that selected function in a desired manner as being indicated on the display unit as the selector member is being further moved in the other direction from the second position thereof.
