VENDING MACHINE CONTROL SYSTEM WITH MALFUNCTION BYPASS ABSTRACT A vending machine control system with a bypass for a malfunctioning column of a multiple column vending machine which has electric dispensing mechanism drives individual to the columns; the system having momentary selection switches for selecting a product from each column by energizing the corresponding drive through a selection path during the initial portion of a dispens- ing cycle; having carrier switches individual to the columns and actuated by the drives for maintaining a relay in a condition wherein the selection switches are energized for such selection by a series connection through the carrier switches during such initial portion, each carrier switch cancelling such condition of the relay by opening the connection and, substantially simul- taneously with such cancelling, energizing the corre- sponding drive to complete the remaining portion of the dispensing cycle through another path which is a portion of such connection; and having bypass switches indivi- dual to the columns and actuated by the drives, each bypass switch serving to restore such connection substan- tially immediately after the connection is opened by the corresponding carrier switch so that, if a malfunction stalls the drive of one column during such remaining portion, the relay can subsequently be maintained in such condition through such connection allowing products to be selected and dispensed from other columns.
