This particular spring is the 0.25N tensioned version which is accompanied by Seimitsu to specific lines of the PS-14-K and KN push button products.

This spring is approximately 25% heavier than a standard PS-14-K push button spring.

Adding/swapping and replacing push button springs is very useful for individual preference and/or higher level play - fine tuning button characteristics to influence rebound of a button can assist with frame perfect execution of certain movesets within a game. This spring also represents a perfect accessory for aggressive players or heavy-handed users who want the most tension and rebound out of their setups.
