Electrical Wiring in the Home/Light switches have gotten out of sync


I have 3 light switches for my hallway. They all work turning lights off and on but somehow, in the last 2 weeks while I was on vacation and my son was home, they have gotten out of sync.  The lights used to be off when all switches were in the off position.  Now the lights are on when all switches are in the off position.  I know this isn't a real big deal but it bothers me after 26 years of working one way that it now works differently.  My son said he didn't do anything and there were no power outages that he was aware of.  How did this change?  Has one of my switches failed even though all work (maybe 4 way became a 3 way???), is it a puzzle of turning lights off and on in different orders, ???   How do I fix it and resync the switches so the lights are off when all 3 switches are down?  Thanks for any help you can give me.


Controlling a light(s) with a switch in 3 different locations means that at any given time in any of the 3 locations the lights could be "on" or "off" with the switch in the up position or the down position. Thats the nature of a 3 way switching system. One day this switch is turning the lights on in the "up" position the next hour its turning them on in the "down" position. Perfectly normal. If you wanted to get it back to where it was before you would need 2 other people to manipulate the other 2 switches by trial and error till you hit the right combination.

"The Frank Williams School of Electrical Construction". My dear old boss is 100 ! and still going God Bless him. I started working for "Tenafly Electric" right out of high school at 19. He was tough but I learned more working for him in 8 and half years than most guys. We did mostly industrial work while doing some commercial and residential so I was fortunate to be exposed to all 3 areas of electrical construction. The guys I worked with were all good guys and I stay in touch with some of them still. Most of us went into our own buisness's which says something about the caliber of the guys I worked with. We had some interesting clients : Wella Corp. of shampoo fame, Farah Fawcett etc, I didn't buy shampoo for 10 years. It was a great place to work. Pan Am the former airline just before they went under, another great place to work, nice clean environment. C&C Metals, the largest button manufacturer in the US at that time, a not so clean environment but a very interesting place to work, lots of machine's cranking out buttons of all kinds but you had to be on your toes, it was a potentially dangerous place to be . All kinds of action going on around you.
