Nowadays we are so used to using the PC and we have become acquainted with track pads, multi-touch displays, etc. that we no longer need the confirmation of a clicking action. You know when you have clicked or double-clicked. You see a graphical reaction of your clicking on the screen and PCs are so fast these days that you practically never have to wait for your PC to respond.
You know when you have clicked or not. So why still hear the clicking sound? Well, it turns out that this is part of switching technology and it is not so easy to remove the physical sound when clicking. We have managed to find a solution. By using some patented switching technology we (finally) have created a soundless/noiseless mouse.
