The LW42A27591/LF301 Dual Power Circuit Switching Control is a 20 A, threeposition, 7wire knoboperated universal rotary cam switch designed for reliable control in electrical panels. Sold as a single unit, it enables dual power circuit switching with a compact, easytooperate interface. Its universal rotary cam switch design supports broad applicability in a variety of control panel configurations. Key benefits Dual power circuit switching: allows selecting between two power sources or circuits from one control element, simplifying panel design and maintenance. Threeposition operation: provides distinct control states in a single control knob, enabling flexible circuit management. 20 A current rating: suitable for many common control loads while offering solid performance margins. Versatile 7wire wiring: supports flexible connections and multicircuit control within a single switch. Universal rotary cam design: compatibility with standard control architectures for easy integration into existing panels. Manual knob operation: precise, tactile control that is simple to use during setup, testing, and maintenance. Single unit solution: delivered as 1 piece for straightforward installation and replacement.
