ABSTRACT:
A system that senses proximity includes a magnet producing a magnetic field and a sensor having a switch. The switch includes a cantilever supported by a supporting structure. The cantilever has a magnetic material and a longitudinal axis. The magnetic material makes the cantilever sensitive to the magnetic field, such that the cantilever is configured to move between first and second states. The switch also includes contacts supported by the support structure. The switch can be configured as a reed switch. When the magnet moves relative to the sensor, the cantilever interacts with a respective one of the contacts based on the position of the magnet during movement.
