Abstract
A switch system comprising a detection device that operates in first and second modes and that conducts first and second currents based on the first and second modes, respectively. A control module input circuit outputs first and second voltages based on the first and second currents. The switch system further includes a control module that receives the first and second voltages and that compares the first and second voltages to first and second predetermined voltage ranges, respectively. Further, the control module detects at least one of a proper operation and a faulty operation of the switch system based on the comparison. The control module receives the first voltage when the detection device conducts the first current and receives the second voltage when the detection device conducts the second current.
