Passenger's Seat (Without Memory)

The passenger seat control switch is purely a mechanical switching module that activates the passenger seat motors without position monitoring capabilities.
Due to it's limited operation requirements, the passenger seat control switch is not equipped with on board diagnostics.
The Passenger Seat control switch is equipped with an overload protection function. If excessive amperage is drawn due to a defective motor or a switch is stuck driving a motor to its end limit, the function activates opening the motor control circuit.
