PURPOSE:To enable a lamp to turn on and off repeatedly while used. CONSTITUTION:A lamp 2 such as a light emitting diode, etc., is installed on the surface of a case 1. A positive electrode plate 4 and a negative electrode plate 5 are placed opposite to each other in a battery chamer 3 of the case 1; a button battery 6 is set between them; and the distance between the positive electrode palate 4 and the negative electrode plate 5 is wider than the thickness of the button battery 6. The positive electrode plate 4 and the negative electrode plate 5 are connected with a positive electrode and a negative pole, respectively, of the lamp 2. When the user walks and runs while carrying the portable alarm lamp 2 like that, the button battery 6 swings in the chamber 3 of a battery and in the case the battery 6 is positioned diagonally temporarily and brought into contact with the positive electrode plate 4 and the negative electrode plate 5 simultaneously, current flows in the lamp 2 and the lamp 2 turns on and off. |
