Claim:
A redundant non-contact switch for reporting a status as closed or open for a first member and a second member that move relative to each other between an open state and a closed state, comprising: a wireless authentication (WA) pair, including: a WA responder attached to one of the first member and the second member; a WA interrogator attached to the other of the first member and the second member; the WA pair configured to register a WA status of closed or open, depending on a WA authentication between the WA responder and the WA interrogator; a magnetic pair, including: a magnet attached to one of the first member and the second member; a magnet sensor attached to the other of the first member and the second member; the magnetic pair configured to register a magnetic status of closed or open, depending on whether a magnet distance between the magnet and magnet sensor is beyond a threshold magnet distance; and the redundant non-contact switch configured to report the status as closed only if both the WA status is registered as closed and the magnetic status is registered as closed.
