I know this may seem like a silly question but I just more want to be sure I can do it without overloading the output.
Lets say I have this little Audio switcher PCB, it’s about as simplistic as you can get which is just what I want.
My multimeter reveals that the onboard switch changes the 6 connections on the PCB like this:
The top 2 points are connected to the middle 2 point although separately down each side… you could join them if you just wanted a mono Audio signal.
And the bottom 2 point connect to the middle 2 point again separately down each side.
Now what I need to do is remove the on board PCB switch and have a couple of relays do the job of the switch.
The Normally closed positions on both relays would naturally be the default state of the switch and then when both relays are triggered they would connect the top connections of the PCB points to the Middle two points… Hopefully that made sense as far as the basic workings of this little PCB goes??
Now what I’m just wanting to make sure about is can I safely have the one of the Arduino pins trigger 2 relays to do this job??
NOTE: See attachment for an image of he switch connection on the little PCB Audio switcher board.
