ABSTRACT:
The illumination device comprises a body, an illumination means, a holding means and a switching means, the last mentioned three means being attached to said body. Said holding means includes a battery and a biasing means made of an electrically conductive material. The holding means is made of an electrically conductive material and is constantly electrically connected to one electrode of said battery through said biasing means. The biasing means is designed to function so as to keep the other electrode of the battery in the state of being constantly electrically connected to one terminal of said illumination means while keeping, in a steady state, the holding means in the state of being removed from the other terminal of the illumination means. Said switching means is movable relative to said body and is designed to displace, by its movement, said holding means in the direction of its axis against the biasing force of said biasing means, thereby permitting the holding means to be electrically connected to the other terminal of said illumination means.
