LED Flashlight--Introduction of LED Flashlight Tactical Switch

The tactical switch was first defined by Surefire. Its principle is basically similar to that of a normal knob switch, except that the contact surface of this switch has been improved. Not only is the front spring installed, but the entire contact surface is movable. It has three working states: one is completely unscrewed, in this state no matter whether the back button is pressed or not, the current circuit will not be connected; the other is in the lighted state, at this time the tail cap is slightly tightened, and if the button is pressed, the It will be connected, and the circuit will be disconnected when it is released; the last one is the constant light state, that is, the tail cap is completely tightened, and the circuit is connected for a long time. Now the tactical switch is explained in detail, and its original intention is to be used for CQB (indoor close combat, which requires the tactical light to be able to light up suddenly, and to be able to detect suspects without exposing oneself), that is, to meet the purpose of lighting up for a short time It must also be able to stay bright for a long time.
