Just splice the switch into the middle of a circuit.
What kind of switch? SPST, DPST, DPDT?

No you don't have to hook up - and + to the switch. Just hook up the positive end of the power source to one leg of the switch, and the other leg of the switch to the cathode leg of the LED. Then connect the anode and the ground together.

That's backwards and may burn out the LED - definitely won't make it light. LED anode goes to positive, cathode to negative (or "ground"). Don't forget you need a resistor in there somewhere too, unless you bought one of those special LEDs with the resistor built-in.S q u e e ! wrote:No you don't have to hook up - and + to the switch.
