Simple USB Switch

I need to connect my keyboard both to my personal and work computers and I didn't find any simple USB switches online (purchased one on Amazon that always wires the 5V lines of both PC, reinjecting power in USB ports !) so I made one with a rotary switch; no electronics parts, 100% reliable.

For this small project you will need :
- 2x USB Type-B female connectors
- one USB Type-A female connector
- a rotary switch (4 circuits, 3 positions)
- a knob
- 2x 1206 CMS LED (optional)
- one 370ohm resistor (optional)
- 4x M2 screws
- a piece of prototyping board (43*20mm)
- some wires

I didn't made schematics.
