Pin / terminal interpretation

Schematic terminal	Pin number	Current meaning in project	Datasheet confidence
COM_1	1	Common for switch 1	Reasonable, but not explicitly confirmed from extracted pin table
COM_2	2	Common for switch 2	Reasonable, but not explicitly confirmed from extracted pin table
NO_1	3	Switched contact for switch 1	Reasonable, but not explicitly confirmed from extracted pin table
NO_2	4	Switched contact for switch 2	Reasonable, but not explicitly confirmed from extracted pin table

Footprint cross-check

From the footprint asset:

4 SMD pads
Pad centers at about x = +/-1.27 mm, y = +/-4.45 mm
Pad size about 1.10 mm x 1.50 mm
Body outline about 6.02 mm x 6.2 mm

That is broadly consistent with a 4-pin SMD 2-position DIP switch footprint.

Mismatches and risk flags

Severity	Finding	Why it matters
High	Project package/case code is DIP, but datasheet/footprint indicate SMD-4P	This can cause incorrect part ordering, wrong filtering in library/BOM workflows, and confusion during manufacturing handoff
Medium	Terminal naming in the schematic is inferred as `COM` / `NO`, but the extracted datasheet text did not return a definitive per-pin table	If pin numbering is reversed relative to the manufacturer drawing, the symbol could map incorrectly to the footprint
Medium	Datasheet extracts contain conflicting values for dielectric strength, operating temperature, and operating force	These should be checked directly on the source PDF page before final publishing or release
Low	Terminal pin types are all currently Unspecified in the schematic	Not usually fatal for a switch part, but clearer terminal typing improves reuse and review quality

Bottom line

The footprint looks plausibly correct for a 4-pin SMD 2-position switch.
The biggest issue is the package metadata mismatch: the part is marked DIP in project properties, while the datasheet and footprint indicate SMD-4P.
The next biggest risk is pin mapping certainty. The current 4-terminal symbol is structurally reasonable, but I do not have a definitive extracted manufacturer pin table from the PDF text to prove the numbering/order is exact.

If you want, I can next do a tighter audit focused only on validating the exact pad-number-to-terminal mapping for COM_1, COM_2, NO_1, and NO_2 against the manufacturer drawing.
