A flashlight includes a conductive barrel, a tubular tail cap member, and a tail cap switch assembly. The barrel has a threaded rear end portion with a contact end face. The tail cap member is sleeved threadedly on the rear end portion, and has an open rear portion formed with a radial inward annular flange that is spaced apart from the contact end face. The switch assembly includes a push button cap made from an insulator material and having a contact support portion disposed in the tail cap member between the annular flange and the contact end face. A cap engaging portion extends rearwardly from the contact support portion and through the annular flange, and is in sliding engagement with the annular flange. A conductive contact member is disposed on the contact support portion. An operating portion is formed on a rear end of the cap engaging portion, and is operable from the open rear portion so as to move the push button cap to move the contact member to contact the contact end face.
