Isn’t a “click” just physically making two connectors touch so that a circuit is made to send the signal of an action? There doesn’t have to be any noise associated does there?
For example, if we used 2 springs, one to hold up the button and another to make the contact with the circuit, the click would be silent. Or maybe something already exists that I can swap out into my mouse?
Doesn’t have to sound awful though if done right - I switched from Logi MX3 to MX4 mouse and it surprised me as it doesn’t have an audible click whole still having some noticeable feedback to it.
