Manually actuatable means are provided for programming or time setting a digital-electronic time switch device which utilizes an analog program input eliminating the need for a separate data display terminal. The time setting system includes a manually adjustable dial assembly having at least one adjustable indicator arm movable about an annular time marking scale and connected through a train to a command encoder. The command encoder includes a wheel connected to the dial train for forward or backward rotation. The wheel is suitably constructed, such as by radial slits to code dial assembly settings for triggering a digital information transducer, such as an opto-electronic device, which signals an electronic counter. The electronic counter adjusts the device data memory by specific time units in relation to the digital information received by the command encoder. The dial assembly inherently indicates the adjusted time setting to the operator in readily observable analog form.
