HDMI + USB 2.0 dual input/one output switch

Based on the GuGuGu625 design and my own usage experience, I made some modifications.
The original design is as follows:
[Verified] HDMI + USB 2-in-1-out Switcher KVM - JLCPCB EDA Open Source Hardware Platform (oshwhub.com).
Functionality is defined as follows:
 
Usage:
1. Connect the left USB1 and HDMI ports to one computer, and the right USB2 and HDMI2 ports to another computer. The bottom USB ports can be used to connect USB flash drives, mice, keyboards, etc.;
2. Use the middle switch to switch. When the left indicator light is on, the monitor and the shared USB device are connected to the left computer; when the right indicator light is on, the monitor and the shared USB device are connected to the right computer;
3. Added diodes allow for independent use of HDMI or USB.
 
Testing:
1. HDMI: 1920x1080, 60Hz, works normally;
2. USB flash drive speed: Large file copy, approximately 38MB/s, basically usable;
3. Button switching speed: USB recognition is slightly faster than HDMI.
 
Soldering:
Used components from the basic library as much as possible to reduce costs.
 
Shell:
I'm not really going to draw it anymore. If you have a male shell of similar size, please share a link with me. Thanks.
