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.

A new board mounted electromechanical device is provided that mounts to a relay substrate to form a low profile reed relay. The reed relay is electrically connected to the electrical contacts via a signal traces and additional electrical traces located on the same side of the relay substrate which connect to the relay's signal and shielding. Additional traces on both sides of the signal traces of the reed relay provide a co-planar wave guide to maintain the desired impedance of the signal path. The reed relay is mounted in an inverted manner into a cut-out in the main circuit board so that the other portion of the reed relay itself is sits within the cut-out in the main circuit board. As a result, the reed relay component is recessed below the surface of the main circuit board resulting in an overall low profile circuit board.

To provide a switching mechanism of which an equipment need not be made large in size nor complicated, and much less, a permanent magnet which may affect a sensor or the like need not be carried about for operation of the equipment. Switching of operation in the equipment 1 is carried out by a reed switch 3 provided inside the equipment 1 sensing a given magnetic field. The reed switch 3, provided with reed relays 4, 5, senses the given field base on magnetic induction and closes contacts of the reed relays 4, 5. The switching mechanism arranges a permanent magnet 7 and a ferromagnet 8 inside the equipment 1, in a state having the reed switch 3 not sense the given field, that is, so as not to induce magnetic induction. As a user brings another ferromagnet (a ferromagnet for operation) 9 near the permanent magnet 7 or the ferromagnet 8 from outside the equipment 1, the magnetic induction is induced to the reed switch 3 to close the contacts of the reed relays 4, 5, which makes it possible to operate the equipment.
