TH2934A3 - Vending machine operated electrical control system - Google Patents

Abstract

This invention discusses the electrical control system that is used to control the operation. Vending machine Consists of a vending machine Selectable electric switch Two or more appliances and an additional lamp indicating the working situation is characterized by the choice of electrical appliances. Can get more than two devices with selectable electrical switches The signal from the electrical switch is sent to the relay circuit of the Electrical appliances When the coin is operated, the coin output signal is sent to the relay circuit, which provides a complete control system of the electrical equipment. The signal from the relay circuit is then sent to Electrical appliances that we want to work with light indicating working situation
