A flashlight includes a cylindrical tube with front and rear ends, and a switch mechanism. The switch mechanism has an end cap, a contact member, a plunger cylinder, a driving assembly, a depressing assembly, and a retainer. The end cap is threadedly engaged in the rear end of the cylindrical tube. The contact member has an annular portion disposed between the plunger cylinder and the retainer, and a number of leg portions which are connected electrically with the end cap. The plunger cylinder has a front threaded portion which engages a front threaded portion of the end cap. The driving assembly is connected with the depressing assembly and is received slidably in the plunger cylinder. The retainer is connected to the front threaded portion of the end cap. A spring member is retained in the retainer and has a front section which extends out of the retainer and a rear section which engages the contact member and the driving assembly. By operating the depressing assembly, the driving assembly is pushed to permit engagement and disengagement of the spring member and the contact member in order to turn on and turn off the flashlight. |
