Two comments on the circuit:
1. If you're willing to add two more diodes, you can make the USB connector two-sided so that it can plug in either way. See http://electronics.stackexchange.com/questions/209941/two-sided-connectorless-usb-on-a-pcb http://electronics.stackexchange.com/questions/209941/two-si... for explanation.
2. The ALPS SKQGAKE010 (http://www.mouser.com/search/ProductDetail.aspx?R=0virtualkey0virtualkeySKQGAKE010 http://www.mouser.com/search/ProductDetail.aspx?R=0virtualke...) is inexpensive and popular. It looks like it's lower-profile than the button used in the current design, which means it'd be more likely to survive for a long time in a pants pocket, jangling along with a bunch of keys.
- conorpp 10y agoThanks for the comments! I never thought of trying to do a reversible USB connection. And it's actually quite easy! The button you point out looks like a better choice. It's about 10 cents cheaper than my current one. Currently sold out with 13 week lead time at Mouser! Must be popular.
- sowbug 10y agoAnother version is this: http://www.mouser.com/Search/m_ProductDetail.aspx?R=SKQGADE010virtualkey68800000virtualkey688-SKQGAD http://www.mouser.com/Search/m_ProductDetail.aspx?R=SKQGADE0... That one requires more force to press. It's also more expensive, but it's in stock now. It has the same footprint, so it'd be good for prototyping.
