Impact Sensor: Description and Operation

PURPOSE
The sensor assembly is an electrical switch which reacts to impacts according to direction and force. It discriminates between impacts that require air bag inflation and impacts that do not require air bag inflation.

OPERATION
When an impact occurs that requires air bag inflation, the sensor contacts close, completing the electrical circuit necessary for system operation. At least two sensors must be activated to inflate air bag.
