The original DipTrace PCB pattern for the B3FS-4002P switch is inaccurate.
Pattern has it as ~10mm long, is actually closer to 15mm.
(Of course, I found that out after I paid for 25 PCBs to be made...)
Included file is correct, according to Omron's data sheet and my measurements.

***edit: My error. The DipTrace pattern refers to the B3FS-1xxx series, which is correct.
My addition refers to the B3FS-4xxx series which is a physically larger switch.

Note to DipTrace: Please detail the series (such as -1xxx), in case other series have differences.

Also, linking the single op-amp LMV321, with a SOT23-5 footprint.
Pins 4 & 5 labelling are 90 degrees out, haven't worked that one out, yet.

I could not locate a PSOP 0.208" 8 pin device, so created this pattern.

The two attached files should be complete for the above files.
They include additional, un-related data.

Also included is data for 2.1mm DC power through-hole male socket
