A track within the motor itself.  Three wires - permanent power, permanent 
chassis ground, intermittent power.
When the intermittent power comes on, the motor starts to move.  Once it has 
moved 5 degrees or so, a wiping contact reaches a copper segment connected to 
permanent power, and the motor continues to move using this as a source of 
power.  It only stops when it drops back off the other end.
