Hi. Does anyone know how to wire this 4 pin on off switch? (How do they actually work?)
Use a multimeter's continuity (beep) mode to verify which poles are connected and disconnected when the switch is thrown. That should be a dual post single throw (DPST) switch. Wire the power wires to either the left or right side terminals (with the switch oriented as in the photo).
If it is DPST, you can wire it to switch both the Hot/Live and Neutral power wires, (which is a European requirement)...and provides a convenient tie point for neutral-to-PT.
Otherwise, the Hot/Live goes to fuse than switch.
That's a good idea Wyatt. DucDone, you would wire the hot wire (black) to one side of the switch and the neutral (white) to the other side. That way you will still cut the power to the amp if the power outlet is wired backwards.
CAUTION - if this is the power switch or a standby switch you are dealing with lethal voltage. Taking answers off an internet forum and assuming they are correct is unwise. If you don't know basic electronics, you should not be working with these voltages - take it to a tech who can do it correctly...and safely. Meanwhile, do some studying in basic electronics. You should know how to read a schematic and it shows how to wire the switch.
If you are switching voltage..............what Silverface said!!!!!!
I just use a multi-meter (as mentioned) it's pretty easy to determine how the switch works. The good thing about using a multi-meter to check continuity you don’t have to deal with voltage. I also mark the lugs some times so I know exactly were connect the wires. You can also find a lot of diagrams of how deferent switches work. On that subject if you are going to be doing lot of testing (voltage readings) you should consider getting a hi quality meter lesson learned the hard way.
