Stan,
I think I found what you mentioned here but I wanted to make sure before I ordered it. I would select the 12V option and I'm looking for the screw connectors on both sides. I did not see any at the $4 price range. A different link showed screw connectors on both sides but when I selected the product I wanted the picture then reverted to show square pins.
I found this for the power supply (it looks like it meets the specs you mentioned) and I easily found the LED toggles.
Thanks again,
Rob
