Abstract: A magnet reed switch assembly. The magnetic reed switch assembly includes a reed switch having a body and a pair of electrical contacts disposed in the body. A ring magnet has a bore, and a portion of the body of the reed switch is disposed within the bore, with the ring magnet positioned close to the pair of electrical contacts. The ring magnet is movable along the axis of the body between a first position and a second position. A plunger includes a proximal end coupled to the ring magnet and a distal end having a sensing magnet. When a ferrous target is disposed near the sensing magnet, the plunger moves toward the ferrous target causing the ring magnet to move from the first position to the second position, and the reed switch to move from an open state to a closed state.
