Most designs use a separate power switch.&lt;p&gt;This isn&amp;#x27;t more common because there&amp;#x27;s a patent covering using a Hall effect sensor in a ring around a flashlight body for this purpose, and the patent holder, Surefire has sued several manufacturers and vendors over it. A well-funded challenge would probably succeed on obviousness grounds, but patent challenges are expensive and I don&amp;#x27;t think the flashlight industry is profitable enough to justify it. The patent expires in three years, so this will probably become more common then.</text><parent_chain><item><author>m463</author><text>I have always wanted a flashlight with a brightness knob, that clicks to off.&lt;p&gt;It is incredibly hard to find this.
