Table
| Symbol terminal | Current pin number | Datasheet function | Check |
|---|---|---|---|
| COM | 1 | Common contact | Function label matches |
| NO | 2 | Normally-open contact | Function label matches |
| DUMMY | 3 | Dummy/mechanical terminal | Function label matches; must not be connected |
Unspecified on all terminals. Suggested improvement: COM and NO should be Passive; DUMMY should be Not Connected, mechanical-only, or otherwise documented as do-not-connect.Common contact, Normally-open contact, and Dummy mechanical terminal; do not connect.Table
| Footprint feature | Current project | Datasheet value | Check |
|---|---|---|---|
| Pad count | 3 through-hole pads | 3 PCB holes/terminals | Matches |
| Pitch | 5.08 mm + 5.08 mm | 5.08 mm + 5.08 mm | Matches |
| Drill diameter | 1.2 mm | Three, 1.2 dia. | Matches |
| Pad copper size | 1.8 mm round/rect | Not explicitly specified in extracted datasheet text | Reasonable; not directly verified |
| Body outline | 12.8 mm x 5.8 mm | 12.8 +/- 0.15 mm x 5.8 +/- 0.15 mm | Matches |
| Pad functions | Pad 1 COM, Pad 2 NO, Pad 3 DUMMY | Datasheet labels COM, NO, DUMMY but does not provide text-extracted numeric pin numbering | Needs visual orientation verification |
| Dummy terminal | Present as pad 3 | Dummy terminal present; do not connect | Matches, if kept unrouted |
Diodes; it should be Switch.Unspecified; COM/NO should be passive switch contacts, and DUMMY should be clearly non-electrical/do-not-connect.Diodes to Switch.Passive.Not Connected or document it as a mechanical dummy terminal that must remain unrouted.Source used
