Ok, My camera is DOA, so no pictures today.
Below are diagrams for my setup for some of the halloween display elements. I bought 10 latching relays, but they were not flip flop capable, so I had to use 2 of them on each element to get the flip flop i needed for the latching element to work. Then, because they are not rated for 110v 10a, I needed to use relays that would handle that. I had those on hand, so rather than buying more relays, I just did a lot of wiring.
it all works, and that is what matters.
The pressure plates(PP) are made by using 18g stranded wire, aluminum foil and cardboard. (I found this on the net months ago, didnt save where I found the idea, I just remember because it is so simple, this is NOT my original idea) Measure and cut off aluminum foil to the same size as your cardboard. (I used wide aluminum foil, so I could make a large PP without using 2 pieces of foil.) Strip about 2" off the end of a piece of wire, spread it out, and tape it to the dull side of the aluminum foil. Now, glue the foil, dull side down, to the cardboard. I then put duct tape around the entire thing, overlapping the edges of the aluminum by about 1". Make 2 of those, same size. Now, get some very thin foam, or lining material. Cut out a sheet a little larger than your cardboard. Cut holes in the middle of the material, and all around the outside. I have more than 50% of my aluminum foil showing. Tape the lining in place, making sure to leave a healthy amount of foil exposed. Now, put the 2 sheets together, aluminum foil together, and tape them together. Get your multimeter out, and verify that you do not have a complete circuit, and that when you put pressure on the PP, you do have a complete circuit.
The first diagram is for a dual channel opposite on/off system. When one is on, the other is off.
The second diagram is for a single channel, but needed 2 110v relays because I have more than 10a of power consumption at startup, so I used 2 relays to make it work. It turns all channels on at once, or off at once.
