Abstract
A high-voltage ('HV') system for a vehicle is provided, and includes a HV source providing HV power, a low-voltage source, a high-voltage interlock loop ('HVIL') switch, and at least one control module. The low-voltage source provides a low-voltage power that is less than the HV power. The HVIL switch is in communication with the low-voltage source. The HVIL switch includes a reed relay and a magnetic element. The magnetic element is selectively positioned within an actuation distance from the reed relay. The HVIL switch is in a closed circuit condition when the magnetic element is positioned within the actuation distance from the reed relay, and is in an open circuit condition when the magnetic element is positioned outside of the actuation distance from the reed relay. The at least one control module is in communication with and monitors the HVIL switch.
