I am considering buying this switch,

I was just wondering what exactly Acc stands for on the switch. I mean i understand that it is connected to ground when it is in one position and power in the other but i was just wondering what it actually stands for.

Re: Switch
Hi,
I suspect it stands for accessory - the terminology used suggests it is intended for automotive use. It won't be connected to ground though - the power and acc terminals will be connected when the switch is one, open when off. The ground connection is needed to power the LED.

Re: Switch
It won't connect directly to ground in the off position, the only purpose of that tab is to provide a negative terminal for the LED.
It is a single pole, single throw switch SPST.
Basically, if you wire it up with the +ve supply to power, your accessory +ve to ACC and connect ground to -ve all should be good. If you get the supply and ACC back to front the LED will remain lit all the time.
