Here's a perfect reason to use \context Voice instead of — or rather,  
in addition to — \new Voice:

%%%%%%%%
\version "2.11.49"

voiceA = \relative
{
        c4 d e g,
        f e e' d
}
voiceAswitches =
{
        s2. \change Staff = "LH" s4
        s2 \change Staff = "RH" s2
}

\score
{
        \new PianoStaff
        <<
                \new Staff = "RH"
                        \new Voice = "RH_voice" \voiceA
                        \context Voice = "RH_voice" \voiceAswitches
                \new Staff = "LH" { \clef bass s1*2 }
        >>
}
%%%%%%%%

Once the Voice context has been created and populated with the notes,  
you are then able to "cram the staff switch information" down its  
throat by referencing it using the \context Voice construct.  =)

Hope this helps!
