Too hot to go to the hangar.... Had some fun making a practice circuit using a switch and a relay. I understand relays but have never wired one. So this was a nice little learning experience. Watched some YouTube videos and got a small LED light and a automotive relay on Amazon. Using switches that I planned for the airplane and some wire I had around the house, I started by making a simple one switch one light circuit. Then I made a one switch two light circuit. Using a DPDT ON-ON-ON switch allows an OFF position then 2 ON positions. This simulates OFF / Wig-Wag only / Wig-Wag + Landing Light positions. Nice afternoon indoor project on a hot day.
