Seat Belt Buckle Switch

D The non-contact type switch is composed of a Hall IC and two magnets, installed into the front seat inner
belt assembly.
D The ejector inside the front seat inner belt assembly and the plate installed to the ejector move when the
seat belt is removed or inserted. The movement of the plate changes the magnetic flux density of the

or insertion, and outputs a signal to the airbag sensor assembly (for driver seat) and occupant
classification ECU (for front passenger seat).
