ABSTRACT:
An advertising device is provided which includes a base and a display piece. The base has a display piece supporting surface and a magnet concealed beneath the surface. The display piece, which is of a size and weight to permit easy handling and carries advertising indicia, has a lamp, an electric battery and a reed switch, all connected in series with one another, encapsulated within the piece. The outer surface of the piece is smooth and uninterrupted and at least the battery and reed switch are concealed from view. The reed switch is positioned wholly within the display piece and physically isolated from the base surface when the piece is resting on the surface, but exposed to a magnetic field of the magnet in at least one position of the piece on the base surface, to change the position of the reed switch contact reeds relative to one another, either to close the circuit through the lamp to light the lamp, or to open the circuit to extinguish the lamp. Preferably, transformer and rectifying means by which the battery can be recharged are also encapsulated within the piece.
