Yes, was told exactly the same thing recently.
It means really the switch is permanently on of course. Whether that's a positive or negative, is debateable. There is a way of activating the minimal without turning the barrel
Compare the above to an ordinary torch, which switches on with no further ado just by sliding the with forward. A way around bypassing the barrel twist would be contact strips fitted inside the barrel
Am no electrical engineer, but the following makes more sense relating to an ordinary common garden torch. Perhaps magnate should consider it too
"When the switch of a flashlight is pushed into the ON position, it makes contact between two contact strips, which begin a flow of electricity, powered from the battery. The batteries are connected in such a way that electricity (flow of electrons) runs between the positive and negative electrodes of the battery. The batteries rest atop a small spring that is connected to a contact strip. The contact strip runs down the length of the battery case and makes contact with one side of the switch. There is another flat contact strip on the other side of the switch, which runs to the lamp (light bulb), providing an electrical connection. There is another part connected to the lamp that makes contact with the positive electrode of the top battery, thus completing the circuit to the lamp and completing the generation of electricity"
