Abstract
An electric control circuit for a safety apparatus of an automotive vehicle comprises an electrically operated actuator connected in series with an electric power source through a normally open switch to actuate the safety apparatus upon closure of the switch and is provided with a storage condenser connected in parallel with the switch and actuator to supply electric energy to the actuator upon disconnection of a conductor between the power source and actuator. In the control circuit, a first diode is connected at its anode in series with the positive electrode of the power source and at its cathode in series with the positive electrode of the condenser to interrupt an electric current discharged from the condenser therethrough, and a second diode is connected at its cathode in series with the negative electrode of the power source and at its anode in series with the negative electrode of the condenser to interrupt a reverse electric current flowing therethrough.
