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 a belt buckle connect switch. The safety belt switches indicate to the restraints control module (RCM) whether the safety belt buckles are connected or disconnected.

The safety belt switches are also used for the driver safety belt warning system and the driver and passenger belt minder.
