A typewriter key is provided which minimizes noise created at both the "make" position of the keystroke and also at "upstopping" when the upward or return movement of the keybutton is stopped. A typewriter key assembly is shown in Figs. 1 and 3 in the upstroke or return position and in Fig. 2 in the make position. The key assembly includes a stem 10 having a pair of oppositely disposed side legs 12 and a cantilever member 14 as can be best seen in Figs. 3 and 4. A buckling spring 16 is disposed within the stem 10 and is positioned to coact with the cantilever member 14. The legs 12 each have a stop member 20 on the outer side thereof with each stop member being provided with a tapered upper surface 22.
