Hi,
Can anyone show on a drawing/schematic how I would wire up the following:
I have 3 wires going to a soundboard (normally no current flowing)
When a current is applied to any of the 3 wires, it plays a corresponding audio message on the sound board
I want the power in the left and right speakers from the main boat stereo system to turn off for for the time the current is flowing in either of the 3 wires (so I can hear the soundboard audio), and the power to return to the stereo speakers when current in 3 wires stops flowing.
I think SPDT Relay is the way to do this .. just not sure what type of SPDT Relay would be needed or what to wire to what terminals.
Thanks so much for any advice.
