Seat Belt Buckle Switch: Description and Operation
SAFETY BELT SWITCH
As part of the supplemental restraint system (SRS), the driver and passenger safety belt buckles are equipped with hall-effect sensors. The safety belt
switches indicate to the restraints control module (RCM) whether the safety belt buckles 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 safety belt switches are also used for the driver safety belt warning system and the driver and passenger belt minder. Refer to Seat Belt Systems.
