Narrative:

I had a complete electrical failure. I lost all navigation and communication equipment. I also lost landing gear indication and fuel gauges. Decided to return to [departure airport]. Descended from 3500 MSL to pattern altitude on a left base approach to runway 31. I could not communicate with the tower. I could not lower my landing gear electrically. I swept the control panel and checked the circuit breakers twice. I then cranked the landing gear down by hand while descending. While crossing the highway on a left base I waggled my wings to indicate no radios. I visually cleared the pattern and made a safe landing behind the only other aircraft I saw in the pattern. I cannot honestly say whether I received a green light. I looked briefly at the tower but my major concern was to land safely as soon as possible without interfering with other flight operations and before I lost something else that could have forced an engine failure. As I taxied to my parking spot; I pointed to my headset and gave a thumbs down to the tower. I then tried to contact the tower by telephone; but could only leave a voicemail. To date I have not heard from them.
