Does the switch on the side of the traxxas 3 channel controller just turn on/offf the power on the 3rd channel of the recivever? I'm looking to be able to switch on/off led lights from the contoller. I'm talking about the red switch on the side of the contoller here. http://www.ebay.com/itm/Traxxas-TQi-...item20cd8e3645
