The light of flashlight aims at phototube, then CMOS logic circuit which adopts battery as power supply will occur switch action to turn on/off the motor of model train or other electric toys. To most small motor, the transistor can use 2N2222A; but the larger motors need power transistor. When using highlightflashlight, to add a baffle to lens to limit th..
