What about an HPL with opened/closed and a HAL/HIL with
pressed/released (as well as a richer interface).  This maps the
low-level functionality to the HPL but maps user semantics to the
HAL/HIL.

Is the generalization we're looking for a Switch, with Button being
one type?  Since switches can be many types:
1. SPST, SPDT, SP3T, ...., SPnT, DPST, DPDT, ..., DPnT, ..., mPnT}
2. momentary or not
3. normally open or normally closed.

seems like Button primarily captures SPST, accomodates (2) and obscures (3).
