Ok so basically the the picture will show you everything.
Since i do not know alot about electronics, i am wondering how do i set this up.
It is a lighted switch that has a LED in the switch so it lights up when the circuit is on.

Connect the +V power source to the POWER lug, probably 12VDC, and the -V of the power source to the GROUND lug.
Connect whatever you are powering ie. mix fan, to the ACC lug and the GROUND lug.
What you are doing in the switch is switching the power that is present on the POWER lug to the ACC lug and also an LED in the handle. The GROUND is there only to allow a full electrical path for the LED in the handle, otherwise its connecction on the switch would be unnecessary.

these type of switches can actually have the ground connected to the ACC(accessory) which should loop it back to the batteries negative terminal...

Well, what this switch is for is a safety switch for my tazer circuit board.
I just want it to have a LED (which it has in the switch) so that i know when its on.
Im not sure i understand exactly what you are saying starman.
Is this what you are trying to say?
If this is wrong, can someone just modify my picture because a pictures worth a thousand words
If this is correct, would the switch still light up.

You can all ways test it on something other then your circuit board. That way if you do it wrong your circuit board wont get hurt. Old flash light, little toy motor, computer fan, ect....

with this type of switch the LED will work as long as there is current between the P and the ACC. it's still a basic switch with or without the LED. there should be a risistor before the LED to keep it from burning out. u don't need the GROUND. it has a GROUND cuz that switch was made to handle much more power. what is the voltage rating on it? i'm curious.

@i-will, likely 12-24v
I am pretty sure that will work... if not, connect the ACC directly to the circuit board, and the ground and circuit board to the negative terminal... ill give you a pic of how i have my led switch for my chamber fan set up, it works on the same principal...

What Starman said sounded aboot right, you may want to play with the terminals and a battery just to make sure.

soldering the neg to the ground is just completing a circuit to nothing. all it's doing is connecting the battery terminals to themselves when ur not using it (off position). a waste of electricity. leave the ground terminal empty unless u want to use it as a second ACC.

Wow, im stupid
I didnt think of using something so simple at a 9v battery. Wow, im sorry i even posted this topic.
Turns out that all you need to do is connect the power and the ground, no need for the ACC. But it still serves a purpose.

It's not there for nothing. It's required to provide a ground return for the LED to light. If you don't care about the LED, you can ignore the ground connection. The "waste of electricity" comment is nonsense...where do you get that idea?
Dax's drawing is correct.

The LED doesnt light without the ground though, so in this case i guess you do need it.

NOOOOO, not true....

The switch is in between the POWER and the ACC connection and is totally necessary. The LED connects to the ACC and the GROUND and lights when the power is turned on, ie, switched to close the circuit between POWER and ACC.

i make my own switches and also used a lot of others. i guess i was thinkin of the wrong one. oh well.
good work, dax.

Starman is right, i just tried it.
Thx for all your advice.
