Keyboards and switch usb

Hello everyone,

I apologise in advance for my writing, I use a translator ^^.
I now own an ultimate blackwidow from 2013 and an imperator mouse from 2012 which still work very well.

I do a lot of telecommuting so I unplug and replug, keyboard/smile, on my professional and personal PCs.

I recently bought a usb switch but the keyboard was not recognized, it turned on and off right away because it seems to me that it requires more power to work.
I plugged the usb switch on the power but I think the hardware is not of good quality as it hasn't changed anything.
The mouse, on the other hand, worked perfectly.

Would you have a USB switch for a mechanical keyboard to recommend?

I thank you for it
