wire identification

[murphcotl]

Hello,
I am looking for help in identifying the wires in the attached picture by color. The back of the switch is a toggle switch for the bedroom led ceiling lights. In this picture I see a top brown and white wire, the bottom of the switch is two orange and white wires and then there are 4 all white whites connected / grouped together.
Does this sound correct ?? The double orange and white wires are the 12v positive and the 4 grouped all white wires are ground?
Any help will be greatly appreciated. House wiring is easier

thanks -- Murph
