ABSTRACT:
A turn-on-and-off device for a flashlight includes an actuating disc located in front of a casing. The actuating disc has a center hole for a lamp to pass through and three posts extending laterally rearward to pass through three position holes in a front end wall of the casing. The actuating disc can be moved by a lamp housing being screwed to move forward and rearward. When the actuating disc is in a forward position, the three posts permit the foremost battery to contact with the lamp bottom to let the lamp lit up. When the actuating disc is in a rearward position, the three posts push rearward the foremost battery, which is then separated from the lamp, which is then turned off.
