The item says its a DC Connector with switch. What does the switch do?

Thanks for the help...


EDIT: Think i found my answer, its for reversing polarity...shame..

The switch is there to cut off the internal supply ( ie batteries ) when you connect the dc plug.
A bit like cutting out the internal speakers when you plug earphones into a radio.

I am with HouseOFwax on this.

The switch isolates the internal supply, usually. It is operated by inserting the plug into the socket.

As for reversing the polarity, I think you are confusing this with some other device.

Is there an easy way to make the switch behave the opposite way?

Why do you want to do that?

What are you trying to do?

I have 3 wires that are all DC well...1 is constant +12V, 1 is ground and the other is a +12V a times, well i when the one is +12v i need a jumper jumped on a power supply...so it would save me the trouble of having to manually flip a switch to jump the jumper.
