How are the different types of airbag sensors different?
The two different types of airbag sensors are mechanical and electrical. Some electrical sensors use electromechanical “bauble and ball” mechanisms designed to release a ball from a magnet, which rolls into a tube before hitting a switch and completing an electrical connection.
Do you have to reset airbag sensor after impact?
Many car models include sensors that automatically reset after an impact. However, not all vehicles are designed this way, and the sensor may have to be replaced or reset manually after an impact. If your airbags have deployed, it’s a good idea to test the sensor.
How can I test my airbag warning light?

Any repairs to the airbag system should be done by an expert.
How does a roller airbag sensor work?
Roller sensors have an internal coil spring component, which in the event of an accident experiences tension. This tension measures intensity of impact, communicating this back to the ECU to determine whether the airbags need to be deployed or not. What’s All The Fuss About Airbags?
Where is the airbag crash sensor located in a car?
The intensity of the collision is also noted and it is used to determine whether or not the airbag should inflate. Where Is the Airbag Crash Sensor Located?
