Siemens 52SA7ADN Selector Switch Illuminated Lens

Siemens 52SA7ADN is a chrome-plated, metal-bodied illuminated selector switch with a short lever and two maintained positions (CAM A). It operates at 24-28V AC/DC and uses an incandescent lamp for illumination; this is a complete device, but the lens is not included and must be ordered separately via a lens kit. The unit is UL-listed under file E22655 and is intended for panel mounting in industrial control panels, providing clear indication of the selected position when energized. Common applications include motor control and process selection in manufacturing environments where a lit selector switch helps operators identify the active circuit. As the 2-position CAM A variant in Siemens' 52S family, 52SA7ADN offers a simple, two-choice control solution for standard voltage systems.
