Part Data Review and Validation
Worked for 2 mins 36 sec
Reviewed the PTS645SM702LFS part against the official Littelfuse/C&K PTS645 datasheet already set on the project:
https://www.ckswitches.com/media/1471/pts645.pdf.Key specs confirmed
- MPN: PTS645SM702LFS / PTS645SM70-2 LFS family coding
- Type: 6 × 6 mm tactile switch, momentary SPST-NO
- Mount/package: straight through-hole, 4 PC pins
- Rating: 50 mA max @ 12 VDC
- Operating force: 1.6 N ±0.3 N
- Height: 7.0 mm
- Operating temp: -40 °C to +85 °C
- Life: 100,000 operations
- Recommended PCB: 4 holes, 6.5 mm × 4.5 mm spacing, Ø1 mm holes per datasheet excerpt
Mismatches / issues flagged
- The schematic symbol has four terminals with correct pin numbers, but pin types are
Unspecifiedand there are no explicit pin descriptions beyond the terminal designators. - The symbol names
NO_1,NO_2,COM_1,COM_2are electrically reasonable for a 4-pin SPST-NO tact switch, but the datasheet only labels pins as1, 2, 3, 4; it does not explicitly call out COM/NO naming. - The footprint pad placement appears consistent with the datasheet’s 6.5 mm × 4.5 mm 4-pin layout, but the layout inspection output reports pad sizes/positions in an ambiguous scaled form, so I could not fully verify drill diameter from the indexed footprint data.
- No datasheet update was needed because the Datasheet URL property was already populated with the official Littelfuse/C&K URL.
