ABSTRACT:
A vending machine control circuit which at relatively low cost effectively provides a lockout arrangement which ensures the delivery of only one article per money insertion and which allows alternate selection of articles when one selection is stalled or jammed. The circuit arrangement requires only two cam-operated switches per product selection, and has a single credit release relay common to all product selections. The credit release relay is energized when a vend relay is energized as the result of money insertion, and a time delay circuit is provided for maintaining energization of the credit release relay after the vend relay is de-energized near the beginning of a product vend cycle.
