Toggle switches allow the switching of electrical circuits by operating a lever. They are used in industrial machinery such as machine tools and robots, as well as industrial appliances such as measuring instruments and broadcast equipment. Toggle switches are classified by size into miniature, subminiature or ultra-subminiature. Flat levers, short levers, long levers, levers with caps, etc., are available in addition to the standard lever. Other types include locking levers that are lifted to operate, toggle switches with larger bushings, and more. These switches are easy to operate. Levers and sizes differ by product and should be selected according to desired application.
