Abstract
An electrically operated control circuit for a multiple selection vending machine with lockout circuits to isolate mal-functioning sections, thereby enabling continued vending machine operations via the remaining functional sections. The lockout circuitry is particularly directed toward sensing and compensating for jammed conditions in the product dispensing mechanisms using a minimal amount of additional circuit elements over non-protected counterpart machines. The malfunction lockout circuitry includes a motor-cam driven embodiment, and a unique thermally sensitive motor thermostat actuated embodiment.
