Yes I agree that these optical silent switches are really expensive compared to other switches, but I just wanted to try them out. You could get a discount code from them, all you have to do is place the switches you want in the cart but dont buy it, just let it wait there and Xbows would send you some messages. Wait till they give you sa discount code. I got 10% off, but i cant remember what was the code. You can try “XBOWS2020” but i’m not sure if that’s the code.
I think the tactility is good regardless of the linear optical switch. The switches that came with my board were optical blacks and the one’s I bought from them were optical silent blacks. I can’t say for the optical clicky switches since i haven’t tried them.
From my observations, the moment you press the buttons (when you depress the switches even just a little bit), the switches would activate. I presume all the optical switches would work this way since its the bottom of the stem that would actuate the button, so long as the light from the board is blocked. the only differences would probably be the weight.
However, that isn’t to say that there would be many accidental presses. The blacks switches are hard enough that you can rest your hands on the keyboard without accidentally pressing some switches. But with regard to softer switches (like gateron optical yellows 35g), they might actuate to the slightest weight on the switches.
