Part Metadata Review and Update
Thought for 2 mins 35 sec
Review complete.
I confirmed the part metadata against the available project data and the TL3315NF160Q datasheet workflow I followed: exact pin counts must match the datasheet, and pin numbers/functions should not be guessed . I also re-confirmed the datasheet URL already in the project against the distributor product page and kept it set to:
https://configured-product-images.s3.amazonaws.com/Datasheets/TL3315.pdfI also normalized the project metadata so
What matches
Manufacturer Name = E-Switch, Part Type = Switch, and Package or Case Code = 4.5mm x 4.5mm SMD tactile switch.- MPN:
TL3315NF160Q - Manufacturer:
E-Switch - Part type: tactile SPST-NO switch
- Package/form factor: ~4.5 mm x 4.5 mm SMD tactile switch
- Pin count: the project has 4 terminals, and the datasheet shows 4 terminals as well, which satisfies the exact pin-count check recommended for part verification
- Datasheet URL: present and valid
- Function: tactile switch, SPST-NO / momentary
- Rating: 50 mA @ 15 VDC
- Operating force: 160 ± 50 gf
- Travel: 0.2 ± 0.1 mm
- Contact resistance: 200 mΩ max
- Electrical life: 500,000 cycles
- Actuator height: 0.55 mm off PCB
- Mounting: surface mount
- Packaging: tape & reel, 5000/reel
Current schematic contains 4 terminal elements:
- pin numbers 1, 2, 3, 4
- all four currently have Pin Type = Unspecified
Assessment
- Pin count matches the datasheet.
- Pin numbering 1–4 is present, which aligns with the datasheet’s 4-terminal drawing.
- However, the datasheet notes the terminal numbers are “for reference only”, so the current symbol should not imply unique functional differences unless those are explicitly documented.
- Pin descriptions are missing on all terminals.
- Pin types are incomplete: all four are
Unspecified. For a switch part, that is weak metadata and should be tightened up during part cleanup. The part-sync guidance specifically calls out pin descriptions and pin types as part of a proper audit
- The project does include a footprint asset:
TL3315NF160Q.kicad_mod - The datasheet includes a P.C. MOUNTING land pattern and package dimensions.
- Metadata-level check: the footprint asset name and package description are consistent with the datasheet.
- Limitation: I could not directly inspect the raw pad geometry of the
.kicad_modasset in this session, so I cannot fully verify pad sizes/spacing against the datasheet drawing yet.
-
Pin Type metadata mismatch
- Project: all 4 pins =
Unspecified - Datasheet/project intent: switch terminals should have a defined electrical type rather than unspecified.
- Project: all 4 pins =
-
Pin descriptions missing
- No
Pin Descriptionproperties are present on the terminals. - This leaves the symbol under-documented.
- No
-
Footprint not fully geometry-verified
- Asset exists and looks correctly associated.
- But I could only verify presence and package consistency, not exact pad geometry.
- Part metadata is now consistent with the datasheet and product listing.
- Datasheet URL is confirmed and set.
- No pin-count mismatch found.
- The main issues are incomplete terminal metadata:
- all pins still have
Pin Type = Unspecified - no pin descriptions
- all pins still have
- The footprint is present and plausibly correct, but I could not complete a pad-by-pad dimensional check in this session.
If you want, I can do the next cleanup pass and update the 4 terminals with proper pin descriptions and pin types.
Fix all mismatches
Check decoupling issues

Thought
- Set Datasheet URL to "https://configured-product-images.s3.amazonaws.com/Datasheets/TL3315.pdf"
Thought
- Set Manufacturer Name to "E-Switch"
- Set Part Type to "Switch"
- Set Package or Case Code to "4.5mm x 4.5mm SMD tactile switch"
