Title: Flashlight
Inventor: TAKEMURA TAKEHIRO
IPC: F21Y101/00
Filed: 2000-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a flashlight which is automatically turned ON when it falls. SOLUTION: A terminal 2b and a support shaft 6 are provided on a platform 7. The support shaft 6 is provided with a pendulum 5 provided with a terminal 2a. One end is connected to the terminal 2a and the other end to the terminal 2b in parallel to a switch 1.
