Method of using reed switch apparatus to control one or more devices
First Claim
1. In a warehouse storage structure having a roll up door and a door track, a method of controlling the on/off condition of a high voltage device comprising the steps of:
- coupling a reed switch to the door track of the warehouse storage structure;
providing a control module circuit receiving a low voltage control signal from the reed switch for controlling the high voltage device, the reed switch having an open state and a closed state;
mounting a permanent magnet member having a constant magnetic field to the roll up door such that the magnetic field is exposed to the reed switch to cause the reed switch to be in one state when the roll up door is in a closed position, and the magnetic field is not exposed to the reed switch when the roll up door is in an open position to cause the reed switch to be in its other state; and
controlling the on/off condition of the high voltage device by the control module circuit receiving a low voltage control signal when the reed switch is in one state and by the low voltage control signal not being received by the control module circuit when the reed switch is in its other state.

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.

8. In a building structure having a door and a door frame, a method of controlling the on/off condition of a high voltage device comprising the steps of:
-
coupling a reed switch to the door frame;
providing a low voltage control signal circuit including the reed switch for controlling the high voltage device, the reed switch having an open state and a closed state;
mounting a permanent magnet member having a constant magnetic field to the door such that the magnetic field is exposed to the reed switch to cause the reed switch to be in one state when the door is in a closed position, and the magnetic field is not exposed to the reed switch when the door is in an open position to cause the reed switch to be in its other state; and
controlling the on/off condition of the high voltage device via a control signal received from the low voltage control signal circuit when the reed switch is in one state and by a control signal not being received from the control signal circuit when the reed switch is in its other state. - View Dependent Claims (9)

10. A storage structure comprising:
-
a door cooperatively engaging a door frame;
a first high voltage device installed in the storage structure;
a first reed switch coupled to said door frame, said first reed switch having an open state and a closed state;
a first low voltage control signal circuit including said first reed switch, said first low voltage control signal circuit interconnected with said first high voltage device; and
a permanent magnet member having a constant magnetic field mounted to said door such that said magnetic field is exposed to said first reed switch to cause said first reed switch to be in one state when said door is in a closed position, and said magnetic field is not exposed to said first reed switch when said door is in an open position to cause said first reed switch to be in its other state, wherein said first low voltage control signal circuit facilitates communication between said first reed switch and said first high voltage device, and said state of said first reed switch controls said first high voltage device between an on position and an off position. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
