Abstract

A reed switch apparatus utilizes one or more reed switches to communicate with one or more devices. In one configuration, the reed switch apparatus utilizes a single magnetic field to simultaneously activate two or more reed switches. In another configuration, two or more reed switches, each acting independent of one another are simultaneously activated by a single magnetic field. Additionally, a method of controlling at least two devices includes exposing a reed switch apparatus to a single magnetic field. Yet another method includes a activating a device via the use of a single reed switch mounted to a portion of a warehouse structure.

Claims

1. A reed switch apparatus for independently communicating with a plurality of devices in a building structure having a door or window assembly, the reed switch apparatus comprising:

a housing having a plurality of reed switches, wherein each said reed switch independently communicates with a separate device, and said plurality of reed switches are activated by a single constant magnetic field generated by a metal alloy magnet member, and

an attachment device for mounting said housing to the door or window assembly.

2. The reed switch apparatus of claim 1, wherein said plurality of reed switches include at least one normally closed reed switch and at least one normally open reed switch.

3. The reed switch apparatus of claim 1, wherein said plurality of reed switches includes at least three reed switches.

4. The reed switch apparatus of claim 1, wherein said activation of said plurality of reed switches is simultaneous.

5. The reed switch apparatus of claim 1, wherein said plurality of reed switches do not share a common circuit.

6. The reed switch apparatus of claim 1, wherein said communication of at least one said reed switch with the separate device is wireless.

7. The reed switch apparatus of claim 1, wherein said plurality of reed switches do not share a common circuit;

and said activation of said plurality of reed switches is simultaneous.

8. A method for controlling a plurality of separate devices with a reed switch apparatus, the reed switch apparatus including a plurality of reed switches mounted to a door track of a roll up door, the method comprising the steps of:

exposing a plurality of reed switches to a single magnetic field;

simultaneously activating the plurality of reed switches with the single magnetic field; and

facilitating independent communication between one reed switch and one device for each of the plurality of separate devices, there being a single reed switch for every device.

9. The method of claim 8, wherein said step of communication includes utilization of a wireless channel of communication.

10. The method of claim 8, wherein each of the plurality of reed switches do not share a common circuit.

11. The method of claim 8, wherein the plurality of reed switches include at least three switches and the plurality of devices include at least three devices.

12. A control system for controlling a first device and a second device, comprising:

a reed switch apparatus having first and second reed switches, each said reed switch having a signal lead and a common lead, said signal and common leads of said first reed switch adapted to controllably connect to the first device and said signal and common leads of said second reed switch adapted to controllably connect to the second device, each said reed switch having open and closed positions with the switch position dependent upon the presence or absence of a magnetic field acting upon said reed switch; and

a permanent magnet member capable of providing a magnetic field sufficient to simultaneously alter said positions of said first and second reed switches as said magnet member and said reed switches are brought in close proximity to each other,

wherein the simultaneous change of switch positions allows said first reed switch to control the first device and said second reed switch to control the second device.

13. The control system of claim 12, wherein the first device being controlled by said first reed switch is a light.

14. The control system of claim 13, wherein the second device being controlled by said second reed switch is an air conditioning system.

15. In a warehouse structure, a method of interfacing with a plurality of separate devices utilizing a magnet member and a reed switch apparatus including a plurality of reed switches, the method comprising the steps of:

mounting the reed switch apparatus to a first component of the warehouse structure;

mounting the magnet member to a second component of the warehouse structure;

coupling a first reed switch in the reed switch apparatus to a first device;

coupling a second reed switch in the reed switch apparatus to a second device,

wherein each reed switch has an open position and a closed position and is magnetically activated and each device has an on position and an off position; and

exposing the first and second reed switches to a magnetic field from the magnet member to change the on-off position of the first device and the second device.

16. The method of claim 15, wherein said step of exposing the first and second reed switches to a magnetic field results in the simultaneous change in the open-closed position of the first and second reed switches.

17. The method of claim 16, wherein said step of exposing the first and second reed switches to a magnetic field results in the simultaneous change in the on-off position of the first and second devices.

18. The method of claim 15, wherein the first reed switch is not coupled to the second reed switch.

19. The method of claim 15, wherein said reed switch apparatus mounting step includes mounting the reed switch apparatus to a door guide or frame and said magnet member mounting step includes mounting the magnet member to a door.

20. The method of claim 19, wherein in the closed position of the door the magnetic field of the magnet member is exposed to the first and second reed switches.

21. The method of claim 20, wherein the door is a roll-up door.

22. The method of claim 15, wherein the first device is an alarm system.

23. The method of claim 22, wherein the second device is a light or an air conditioning system.

24. The method of claim 15, further comprising the step of:

coupling a third reed switch in the reed switch apparatus to a third device; and

wherein said step of exposing the first and second reed switches to a magnetic field further comprises exposing the first, second and third reed switches to the magnetic field from the magnet member to simultaneously change the open-closed positions of the three reed switches.

25. The method of claim 24, wherein the first, second and third reed switches are independent of one another.

26. The method of claim 24, wherein the first, second and third devices are independently coupled to the first, second and third reed switches respectively.

27. The method of claim 26, wherein the three devices include an alarm system, a light, and an air conditioning system.

28. The method of claim 24, wherein said coupling steps comprise a first circuit including the first reed switch controlling the first device, a second circuit including the second reed switch controlling the second device, and a third circuit including the third reed switch controlling the third device, wherein the first, second and third circuits are independent of one another.

29. The method of claim 28, wherein the plurality of reed switches include at least one normally closed reed switch and at least one normally open reed switch.
