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 Translated with www.DeepL.com/Translator (free version)
