How do I wire up a relay to control a DPDT button, I'm trying to bypass the actual button press and control it via software.Thanks.
You can't easily. As a DPDT button will have two of the contacts in a normally closed state you can't just wire a DPDT relay contacts in parallel with the button's contacts and get the same reaction as the button pushes as your relay contacts won't force open the button's normally closed contacts. You can totally replace a DPDT button with a DPDT relay, but you can't have them work properly in parallel where either can control the circuit.
That make sense?
