ABSTRACT:
A cooking cycle timer includes two timing circuits, each incorporating an oscillator and a counter. The first timing circuit times the first portion of a cooking cycle, and the second timing circuit times a predetermined second portion. At the end of the first portion, a visible indicator is turned on to indicate that the predetermined second portion of time remains in the cooking cycle. At the end of the second portion, and thereby the end of the cooking cycle, the visible indicator and an audible indicator are operated in pulsed fashion through the operation of a third oscillator. Visible indication is also provided during the first portion of the cooking cycle to show that the timing circuit is active.
