 It is a Stema Analog SPDT Switch Metro and it is running over the Stema for power ground and signal to the analog switch board and then I have this orange wire is one audio input this white wire is a second audio input and then the green is the output for the audio whichever one I'm switching to and that's all going into a little powered speaker. Both of those audio sources are running into the normally open the normally closed switch so here's every four seconds the sound should switch. Switches to iPod. Switches back to Mario there. Now make it a lot faster. So kind of like a little DJ fader is the Stema Analog SPDT Switch with the Max 4544 chip.
