An occupancy indicator for a door, and a method of use, one embodiment comprising a magnet a switching apparatus activatable by a person, a signaling device adapted to indicate one of at least two states, and a biasing mechanism. One embodiment may not be comprised of a magnet but may be comprised of a bolt assembly having a plurality of biasing mechanisms. The magnet or bolt assembly, switching apparatus, signaling device, and biasing mechanism are operatively coupled to automatically provide a signaling device state upon the door opening.

I claim: 1. An occupancy indicator comprising: a housing; a magnet; a lever; an arm; a switching apparatus activatable by a person; a signaling device adapted to indicate one of at least two states; a biasing mechanism; and wherein, a first end of the lever is operatively coupled to the magnet and

I claim: 1. An occupancy indicator comprising: a housing; a magnet; a lever; an arm; a switching apparatus activatable by a person; a signaling device adapted to indicate one of at least two states; a biasing mechanism; and wherein, a first end of the lever is operatively coupled to the magnet and a second end of the lever is coupled to a first end of the arm; a first end of the biasing mechanism is operatively coupled to the magnet and a second end of the biasing mechanism is operatively coupled to the housing; a second end of the arm is operatively coupled to the switching apparatus; and the arm being operatively coupled to the switching apparatus whereby a movement of the arm will cause the signaling apparatus to change the signaling device from one of the at least two signaling states to an other. 2. The occupancy indicator of claim 1 wherein, the biasing mechanism is a spring; and the switching apparatus includes a knob. 3. The occupancy indicator of claim 2 wherein the switching apparatus further includes: a radial bearing; and a shank; wherein the radial bearing is operatively coupled to the second end of the arm; the radial bearing is operatively coupled to a middle portion of the shank; a first end of the shank is operatively coupled to the knob; and a second end of the shank is operatively coupled to the signaling device. 4. The occupancy indicator of claim 1 in combination with a door and a door jamb wherein, the magnet, the biasing mechanism, and the housing reside within the door when installed, and the biasing mechanism automatically positions the magnet proximal the housing in a retracted position upon the door opening and breaking magnetic attraction between the magnet and the door jamb. 5. The combination of claim 4 further including: a magnet reception cavity, the magnet reception cavity being coupled to the housing proximal the magnet; and a strikeplate, the strikeplate being of ferromagnetic material and positioned proximal the magnet when the door is closed. 6. A combination comprising: a door, the door comprising an outer door surface, an inner door surface, and at least one side edge door surface; an occupancy indicator comprising a switching apparatus, a bolt assembly including at least one biasing mechanism, and a signaling device, the occupancy indicator not being associated with a lock and being adapted to automatically provide a signal upon the door opening, wherein a bolt of the bolt assembly includes one of a magnet and a ferromagnetic material; a door jamb; and a strikeplate, wherein the strikeplate includes an other of the magnet and the ferromagnetic material; wherein, the signaling device is coupled to the outer door surface, the switching apparatus further includes a knob coupled to the inner door surface, the biasing mechanism provides a force substantially opposite a magnetic force between the bolt and the strikeplate, and the bolt assembly is adapted to extend towards the at least one side edge door surface and retract to a non-extended position upon the door opening. 7. The combination of claim 6 wherein, the bolt assembly further includes at least one biasing mechanism and is operatively coupled to the switching apparatus and the signaling device;and the door further includes: at least one bore through the outer door surface and inner door surface, and a hole in the at least one side edge door surface, the hole intersecting with the at least one bore. 8. A method of displaying an occupancy status for a room using an occupancy indicator, the occupancy indicator comprising, (i) a housing, (ii) a bolt made of one of a magnet and a ferromagnetic material, (iii) a lever, (iv) an arm, (v) a switching apparatus activatable by a person, (vi) a signaling device adapted to indicate one of at least two states, and (vii) a biasing mechanism, the method comprising: closing a door having the occupancy indicator; displaying a first occupancy status on a door outer surface when the switching apparatus is in a first position; loading the biasing mechanism from a door inner surface by moving the switching apparatus from the first position to a second position whereby moving the bolt proximal a door edge; displaying a second occupancy status on the door outer surface when the switching apparatus is in the second position; and holding the second position of the switching apparatus by magnetic attraction of the bolt and a strikeplate made of an other of the magnet and the ferromagnetic material against a biasing of the biasing mechanism. 9. The method of claim 8, further comprising: opening the door having the occupancy indicator; unloading the biasing mechanism by eliminating the magnetic attraction of the bolt and the strikeplate upon said opening of the door whereby moving the switching apparatus from the second position to the first position and moving the bolt distal the door edge automatically occurs from the biasing of the biasing mechanism. 10. The method of claim 9, wherein the biasing mechanism is a spring. 11. The method of claim 9, wherein said moving the switching apparatus further includes turning a knob.
