Safing Sensor: Description and Operation

SAFETY SENSOR AND ELECTRIC SENSOR
Safety sensor and electric sensor are built into the airbag control module and side airbag sensor. Safety sensor is the pendulum type sensor. If the sensor receives a frontal or side impact exceeding a certain limit the mass in the sensor moves forward to turn the switch ON.

The electric sensor consists of the semiconductor type sensor which senses the deceleration at collision by the change of the electrical resistance and the impact sensing circuit.
