Abstract
Abstract When a cycle selection button is depressed, it causes a selected wire to be torsionally stressed to cause the selected pin to be biased downwardly against the surface of the rotary disc. The disc is carried by the timer shaft which is moved outwardly during the selection/positioning operation. The disc has various radially and circumferentially positioned holes into one of which a selected pin may drop to thereby correctly position the timer at the start of the selected cycle. Three holes are provided in the disc on the radius of the ''''soak'''' pin and a masking arrangement covers or uncovers, as the case may be, the ''''soak'''' holes so only that hole which properly combines with the selected cycle is operative. The masking arrangement is actuated by one of the possible cycle pins. Therefore, a ''''soak'''' period may be selected to precede any of a number of cycles while employing only one ''''soak'''' button and one ''''soak'''' pin.
