How to switch between two tables?

What kind of switch (on off on) can switch two different circuits at the same time?

• I am wiring LEDs in my car. I have power and ground running to my sub so they flash with the music. But I also want to have a third position on the switch so I can run the lights straight to the battery and have them stay on... A normal on off on switch will not work unless I use two of them because I not only need to switch the power but I also have to switch the ground so no power is going through my amp? What kind of switch do I need???

• Answer:

  Double pole double throw center off switch will do two different circuits without crossing or joining them. http://www.amazon.com/DPDT-Heavy-Duty-Toggle-Switch/dp/B001TJ6OBU/ref=pd_cp_e_1 http://www.amazon.com/6-Terminals-DPDT-Toggle-Switch-250V/dp/B0055NFMKK/ref=pd_cp_e_0 The above are momentary on (the switch springs back to off) Here is an on-on one (stays on in both directions, you turn it off at center) http://parts.digikey.com/1/parts/980809-switch-toggle-dpdt-20a-pnl-seal-s6aw.html
