A flip-flop basically transfers the signal in another direction after a certain amount of time....or by choice. Let's say you have two separate rooms, both at 12/12. From midnight to noon one room would recieve an electrical signal and from noon to midnight the other would recieve it. Hope this helps!


Have a good one!:thumbsup:
Psycho4Bud Reviewed by Psycho4Bud on . 2 room flipflop relay Hello all, new to this site it is full of great peeps and knowledge. I am a hardcore Do It Yourselfer. I am asking this community for some help. I am interested in building a 2 room 4 ballast 8 lamp flipflop relay system. These are super expensive from hydro shops like $400 just for the one I would like to build. I know it works with relays But they need to be strong enough to flip 1000 watt HPS systems. someone must have one and could possibly post pics then we could do a how to on building Rating: 5
