The click is unnecessary in the Alps switches and just adds sound without adding much feel. In a Model M, the click IS the actuation of the switch in that when the spring buckles and, thus, clicks, the hammer presses on the membrane. On the Alps, the click is just the leaf slamming against the casing of the switch; the switch is activated by another mechanism. I found a "parts only" AEKII on ebay for about $3.
