I'll try to explain the best I can so if it's confusing I apologize in advance.

I installed a new head unit. It has 1 rear USB. I want to use a USB hub for multiple devices without the need to plug & unplug constantly. I bought a Switchable USB hub. It has 1 USB in and 4 out. Each out has a mini rocker switch with an indicator light on the PCB (not on the switch itself). I will be hiding the hub somewhere in the dash and routing a USB behind the glovebox for a SSD, the ashtray (I'm modifying it) for USB flash drives, and one to the center console for phones, tablets, etc. I probably won't use the 4th but I might just route it to the back seat area.

On the hub, each rocker has 2 posts. I will desolder each rocker, solder in 2 wires & route them to the overhead console area where I will be mounting the new switches. Easy enough.

Here is my question. Are there 4 post illuminated rockers? 2 posts +&- for the switches indicator light (powered by the Blazer's 12v) and 2 posts which connect to the hub to activate the USB port. I need 12v side & the hub's side to be separate. I am almost positive that they exist as I've seen tonnes of 4-post rockers but there is no indication if the 2 pairs of posts are separate. Do they have a specific name or designation?

My reason for doing it this way is, first, because the HU's USB only puts out 1A so I'll have to disable the indicator lights on the hub and the hub will be hidden in the dash so I'd never see them anyways, and second, when it's dark I need to see which switch is active. Any thoughts?

 

Not sure if those exist or not but you could use a lighted rocker switch to activate a relay
