Abstract: An appliance timer incremental drive is provided with an electronic circuit that generates a nonvarying camstack motor advancement pulse that cooperates with a cam-operated motor control switch. When the motor control switch is closed, a power circuit is completed with a camstack drive motor and the camstack rotates. When the motor control switch opens, the power circuit is also open, so the camstack is stationary. The camstack remains stationary, delayed, until the electronic circuit, which operates independently from the camstack, provides a nonvarying camstack advancement pulse to power the camstack drive motor to rotate the camstack.

Abstract: A touch plate assembly for a digital control device. The touch plate is sectioned off into a plurality of touch switch areas, each of which represents certain information to be entered into the control circuit. The touch plate and a printed circuit board, carrying the detection circuitry are held in place by a housing which may carry other circuitry as well. Electrical connections between the detection circuitry and the touch switches are made by resilient spring contact members rigidly mounted on the circuit board and soldered in place as a component. A combination shield-filter assembly is bonded to the back of the touch plate. The shield-filter assembly includes a metal-polyester laminate having windows therein, through which the spring contact members make electrical contact to contact areas on the touch plate. In addition, certain portions of the metal layer are removed so that light from a light source located on the printed circuit board may be seen by the user of the control.
