ABSTRACT:
A timer control circuit for controlling the ON-OFF operation of a controllable current conducting device, such as an indicator lamp or a semiconductor power device, and for keeping the device in a given operating state over a readily adjustable time interval, that utilizes relatively few components and is of low cost construction. The circuit includes principally resistive-capacitive timing means and transistor switching means, the device being coupled with the transistor switching means which, in addition to selectively connecting the device in and out of the circuit as a function of the timing cycle, feeds back a threshold voltage to the timing means as an integral parameter in determining the time interval.
