Simple USB Switch
Description
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 prototyping board (43*20mm) - some wires I didn't made schematics, the wiring is obvious.
