These replacement springs are made to address a few common issues with NMB's 725 series switches, commonly known as "Space Invaders" or "Angry Bears". Firstly the original springs have a tendency to get lost while opening the switches or even just pulling keycaps off; these new springs can not only replace the old ones but their shorter length and thus lower static load reduces the "jumping bean" effect so that they are less prone to being lost. Additionally their shorter length makes them much lighter on the top of the stroke, more similar to MX, Alps, and other common mechanical switches.
