A switch butterfly assembly for use in compact snap-action switches includes a pair of movable switch contact blade members, each being formed of a first end portion, a substantially flat mid-portion, and a second end portion all integrally joined together. The second end portion has a generally curvilinear-shaped configuration and is formed of a vertical section and a C-shaped curved blade section. The intermediate area of the C-shaped curved blade section is disposed opposite the vertical section so as to form an annular space therebetween. The vertical section has a first bend integrally connected to the mid-portion and a second bend integrally connected to the C-shaped curved blade section. The C-shaped section has an upper movable contact blade portion located outwardly from the second bend and a lower movable contact blade portion located outwardly from the free end thereof so as to reduce the stresses created upon the movable contact portions and thus increasing the useful service life of the butterfly assembly.
