1. A high-voltage (“

  • HV”

    ) system for a vehicle, comprising;

    a HV source providing HV power;

    a low-voltage source providing a low-voltage power, wherein the low-voltage power is less than the HV power;

    a high-voltage interlock loop (“

    HVIL”

    ) switch in communication with the low-voltage source, comprising;

    a reed relay; and

    a magnetic element that is selectively positioned within an actuation distance from the reed relay, wherein the HVIL switch is in a closed circuit condition if the magnetic element is positioned within the actuation distance from the reed relay and in an open circuit condition if the magnetic element is positioned outside of the actuation distance from the reed relay;

    at least one control module in communication with the HVIL switch, the at least one control module monitoring the HVIL switch and sending a signal to deactivate supply of HV power if the open circuit condition is detected.
