Engineer's notes — electrical baseline
Treat the raw specification table as authoritative for siemens A6X30139414 (KEY-OPERATED SWITCH CES. I>O-II); category path: Switches > Configurable Switch Components > Configurable Switch Bodies; confirmed specs: series: 3SU1; Type: Maintained, Momentary; Package: Box; Product Status: Active. Cross-check electrical limits, mounting style, output type, and lifecycle status against the target panel or machine design before freezing the BOM line or authorizing a field swap.
Commissioning field notes
Before energizing or replacing the module, align cabinet power rails, wiring plan, load type, terminal layout, and temperature class with both the manufacturer documentation and the as-built BOM.
Selection notes for footprint and electrical verification
Approve this line only when MPN, manufacturer, series, supply voltage, I/O style, mounting, and application role match the design intent. For alternates, diff the same fields first, then validate software/project hooks.
