<p>PROBLEM TO BE SOLVED: To make a luminair at the time of an earthquake also serve as a flashlight, by making switching, between the conditions of free and stop oscillation of the pendulum of a vibration sensor, by the mechanical action of a stopper. SOLUTION: A lever 102 is protrudedly arranged in a part of the installing surface of the bottom part of a flashlight 100. The lever 102 is movably pushed outside with weak flexible force, and when the flashlight 100 is installed on a desk, etc., the lever 102 is pushed into the flashlight 100 by own weight; and when the flashlight 100 is lifted up, it is moved to a range where the flashlight 100 is stopped by a stopper 112. Here, other stoppers are provided on the upper part of the lever 102, and contact electrodes 124 are arranged at uniform intervals in positions where the contact electrodes 124 contact the stoppers. The fixed electrode 121 of a vibration sensor 120 retains a fixing support 122, and a pendulum 123 is connected, so as to move freely, to the fixing support 122, to obtain an electrically conductive condition when the pendulum 123 is oscillated to contact the contact battery 124.</p> |
