Abstract
An interface between a merchandising machine which requires a voltage of a first magnitude for its operation and a coin mechanism which operates at a voltage of a second magnitude in which each selection of the machine is provided with a customer-operated double-pole switch, one pole of which is connected to the coin mechanism to complete the circuit of a relay through the second magnitude voltage source if a sum in money aggregating the purchase price of the article corresponding to the operated switch has been deposited. Completion of the relay circuit closes a switch to complete a circuit from the first magnitude voltage source to the selected unit operating element through the other pole of the operated double-pole switch.
