Seat Belt Buckle Switch: Description and Operation
SAFETY BELT BUCKLE SWITCHES
As part of the SRS, the front safety belt buckles are equipped with safety belt buckle switches. The safety belt buckle switches are comprised of
integrated circuits called Hall-effect sensors. The safety belt buckle switches (Hall-effect sensors) are located in the driver and front passenger safety belt
buckles. The safety belt buckle switches indicate to the RCM whether the safety belts are buckled or unbuckled. The RCM uses this information in
determining the deployment rate of the dual-stage driver and passenger air bag modules. The RCM also communicates the driver safety belt buckle
switch status to the instrument cluster module, which monitors the information to control the safety belt warning indicator.
