Thanks Greywolf - that clears it up nicely.
I think my confusion was arising because I wasn't sure which part of the circuit needed to pass through the PC-8. Now I know it's the "power" leg.
If I have a simple circuit for low-powered devices, such as USB outlets to charge a phone/GPS or some LED lights (basically devices that don't require a relay), and I want the ability to turn said circuit on/off, can the switch be placed anywhere in the circuit? I guess the only proviso would be that it be capable of handling the current in the circuit?
On a high-power circuit that is triggered via a relay, where would the on/off switch go? On the circuit that actually causes the relay to switch on?
Thanks for your outstanding assistance!
