Re-add a 'default' case in STATE_KEY_ON_DELAY During the merge, I accidentally dropped a default case in one of the switch statements when trying to silence a warning. This resulted in a 18-byte increase in binary size and a slighly more fragile code. Re-adding the default case shrinks the binary back down to 1590 bytes.
