Title: Tactile Switches with 2 tactile bumps?
Post by: filcomanfilthy on Sun, 21 April 2019, 10:49:28

Hi, I am wondering if there are any tactile switches that have an initial tactile bump when the actuation point is reached for a keystroke to register, and a second tactile bump when the switch bottoms out.

Matias quiet clicks have a double bump.

What is a "tactile bump when the switch bottoms out"?  Bottoming out is the ultimate tactility...it's a sheer wall.

It's not exactly a second bump, but the force curve of Halo switches might be what you're looking for in that they have a small bump at first with a bit of a valley and then the force required increases significantly as you approach the bottom out point.  So quickly after actuating that it almost feels like a second bump.

But at the same time I'm honestly not sure what you're looking for...

Side-note: There is a category of rare switches that are "double action" (https://deskthority.net/wiki/Double_action).
They have two different actuation points, but not always two tactile events.
