Anti-Submarining Switch - Power Seats / STE

The anti-submarining switch prevents the driver or passenger seat from tilting too far forward which could allow the occupant to slide under the seat belt in the event of a accident.

This switch is installed in the seat which interrupts the current feed to the seat inclination adjustment actuator motor as soon as the seat height at the front is 10 mm (0.4 in) lower than the rear.
