1. A seatbelt buckle detection system for use with a controller and a power source coupled to the controller, the system comprising:
a seatbelt buckle housing for being mounted to a vehicle; a printed circuit board or other type of carrier fitted with one or more electrical conduits mounted within the buckle housing; a pair of leads extending along the printed circuit board for being operably coupled to a power source and a controller, the pair of leads defining part of a circuit; a first resistor of the circuit; a second resistor of the circuit; a switching device mounted to the circuit; a slider slidably engaged with the printed circuit board; a switching actuator mounted to the slider; a translatable ejector attached to the slider; a first current loop path completed with the ejector and switching actuator in a first position to actuate the switching device into a first configuration, the first current loop path including the first resistor and shunting the second resistor, the first current loop path providing a first measurable current output from the circuit; a second current loop path completed with the ejector and switching actuator in a second position to actuate the switching device into a second configuration, the second current loop path including the first resistor and the second resistor in series, the second current loop path providing a second measurable current output from the circuit that is lower than the first measurable current output; a third measurable current output defined by a fault in the system, the third measurable current output being different than both the first and second measurable current outputs to indicate the fault; and wherein the current output of the circuit is detectable by a controller to determine whether the ejector is in the first position, the ejector is in the second position, or the fault in the system is has occurred. |
