I’d like to let the Arduino control a VGA switch. It’s a Kramer VP-211k that has connectors for a remote (dry switch). I’ve meassured it to about .01V-.03V. I have used the device with a flip switch (on-off-on) to close the circuit and it works perfectly. But how do I replace the flip switch with an Arduino? See attached image.
It’s way to low current for a relay, right?
The MOSFETs I’ve been looking at go as low as 5V but not lower.
Or some other kind of transistor?
I think I’m missing something major conceptually. What component do I use here to close the circuit?
