ABSTRACT:
The present invention is directed to a barricade light control switch apparatus for operating a battery powered barricade light unit. The apparatus comprises a light unit housing, light source, battery, and circuit means for controlling operation of the light source, and a reed switch. A magnet retained by a magnet carrier is positionable in either of two positions and controls operation of the reed switch. When the magnet carrier is in a first position the magnet is positioned in proximity to and closes the reed switch. When the magnet carrier is in a second position the magnet is positioned away from and opens the reed switch. Retention means preclude unintended movement of the magnet carrier. A method for controlling a barricade light unit is also disclosed.
