long time lurker, first time poster in need of help.
I am attempting to wire all my gaming systems so that I can access them all by simply turning on a few switches without having to plug/unplug anything. I came up with the following system (see diagrams below):
All my routing is good, and I'm getting the right sounds from the system I want, when I select the correct routing. My issue is Video. On all the Sega consoles I'm either getting a black screen, or black and white, or colored for 1-2 seconds then Black, or sometimes the image is scrolling. I have the same issues for basically all RCA/Component connections with a few system working properly like the N64. When hooking the systems directly to the receiver or the radio shack switch they seem to work properly. Here's a list of the hardware:
Most of my wires are from Monoprice but some of the RCA wires I picked up from https://www.amazon.com/gp/product/B002P8WME2/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
The radio shack switch is : https://www.amazon.com/gp/product/B006PIPOBQ/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
Monoprice Switch: (Can't find this online, I bought these years ago.)

I used one of those pelican switches(unpowered) before I bought the radio shack, which had the same results. I thought going with a powered switch might help, but it didn't. In fact the ps2/sega saturn worked with that switch, now they don't with the radio shack. I'm not really sure what is causing this issue, but any help would be highly highly appreciated.
