I am trying to replace a analog switch (the switch is a momentary button in a low current DC situation) with optocoupler.
Is it possible to use an optocoupler as a switch (i.e. just on/off)?
Ignoring the current/voltage that optocoupler is capable to output.
Is it possible to use an optocoupler to short two wires carrying low current DC signal?
Basically I am trying to hack a circuit and add Arduino control to it and from my testing I am unable to obtain much more info.
Hope this makes it clear...
