This invention is a safety device of an industrial compressor. Its purpose is to obtain an electronic safety device which is composed of an IC, a LED and transistors, so that the cost of production is cheap and the manufacturing process is simple, and so forth. A sensor switch of compressor air temperature and a sensor switch of cooling water and a pressure switch and a TSW are connected between a logic circuit, which is composed of a OR gate, two AND gates and a flip- flop, and three flip-flops, which have three LEDs. Hence, the output of a logic circuit controls the solenoid valve which supplies fuel.
