A small, curved piece of stainless steel sits above a circuit board contact. When pressure is applied from above, the dome collapses downward, touches the contact point, and completes an electrical circuit. Release the pressure, and the dome springs back to its original shape, breaking the connection.<\/span><\/div><div class=\"rich-text-paragraph\" data-eleid=\"11\"><span class=\"text-only\" data-eleid=\"12\">That&#8217;s the basic idea anyway. The reality involves some interesting engineering that determines how the switch feels, how long it lasts, and how reliably it performs over millions of cycles.
