ABSTRACT:
A coin operated vending machine has a pair of spaced conductors mounted on a coin chute and in position to be bridged by any electrically conductive liquid squirted into the coin slot. Bridging of the conductors by the liquid completes a circuit which disconnects vending circuitry from its power source. The spaced conductors are mounted on a non-conductive support which prevents a coin itself from contacting and bridging the conductors.
