In step S10, the control switch 200 is in the first control position as the initial state, and the control unit 100 is in the first state, and the first state is preferably to control the single-switch flashlight to be turned off, i.e. to keep the light source 300 off.

Regarding steps S41 and S42, the control unit 100 maintains the current state when the control switch 200 is moved back to the first control position in the third state or the fourth state. However, when the control switch 200 moves back to the first control position again, the control switch moves again, and the control unit 100 enters the fifth state when the first control position transits to the second control position; preferably, the fifth state is a control mode in which the single-on control light source 300 is controlled to be turned off, and the third state or the fourth state is suspended.
Regarding steps S51 and S52, in step S42, the control switch 200 is in the transition between the first control bit and the second control bit, and the following operations are performed to enter different states: 1. the control switch 200 is restored to the first control position and to the third state or the fourth state; 2. the control switch 200 moves to the second control position and enters the sixth state. Preferably, the sixth state is to maintain the extinguishment of the fifth state, and according to step S60, when the control unit 100 regenerates the first control signal in the sixth state, it returns to the first state, i.e. controls the single-switch flashlight to be turned off.

Specifically, the processor 111 receives different control signals according to the positions of the control switch 200, such as the first control bit and the second control bit, and enters different states according to the changes of the two control signals, such as generation and disappearance. And according to different states, the processor 111 outputs different signals or does not output signals to the grid of the field effect transistor Q1, so as to control the on-off of the field effect transistor Q1, and the power supply 400 supplies power to or cuts off the power of the light source 300. For example, the processor 111 does not send a signal to control the fet Q1 to turn off, the processor 111 sends a signal with a high duty ratio and a high frequency to control the fet Q1 to turn on, and the processor 111 sends a signal with a high duty ratio and a high frequency to control the fet Q1 to turn on repeatedly with a low frequency carrier, even if the light source 300 is flashed.
