Typical Applications
Square D 2601-BG-1 /B reversing switches excel in manual reversing control environments requiring across-the-line motor starting. Common applications include: machine tools (lathes, milling machines, planers, grinders, shapers, boring mills), woodworking equipment, door operators, small hoists, and conveyor belt systems. The unit is particularly suited for fixed-speed, bidirectional motor control where simplicity and reliability are paramount and where across-the-line starting is acceptable or where additional current-limiting devices are installed.
