Abstract
An electric control circuit for a passenger protection system in an automotive vehicle includes an electric power source, an acceleration sensor arranged to produce an acceleration signal therefrom in the occurrence of a vehicle collision and an electrically operated actuator including a primer having a first terminal in series with the power source and a second terminal in series with the acceleration sensor to be grounded therethrough in response to the acceleration signal from the sensor, wherein the second terminal of the primer is directly grounded when a voltage appearing at a conductor between the second terminal of the primer and the acceleration sensor becomes lower than a predetermined value to ensure activation of the primer.
