ABSTRACT:
An improved vending machine power switching apparatus in which a single power switching circuit is associated with a plurality of load selecting relay switches and a switching control circuit, in which the control circuit controls the order of switching of the power switch and relay switches, such that any relay switch is always closed before power is delivered to its associated load and is always opened after power is removed from the load, and the power is applied and removed by the power switching means.
