I wanted a way to house a Lighter Socket and a USB Socket in my campervan, but I also wanted a 1 switch to power them off, cause of the pesky blue LED Lights...

I saw some in here but all had "individual" switch per socket, which was not my use case, so I designed my own.

I've also added a back box that works for my purpose since I have a mdf board in the middle, might not suit for everyone. The depth of the box is 45mm.
