Abstract: 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.

Abstract: A push button operated electrical switch is disclosed including a resiliently deflectable contact element including a concavo-convex portion and a pivotable contact arm. Upon actuation, the concavo-convex portion deflects and extends contacting a ramp which causes the pivotable contact arm to pivot into wiping type contact with a stationary contact.

Abstract: A sub-miniature snap-action switch which can be manufactured efficiently and reliably with minimal reliance on tedious hand assembly. The switch includes a novel pivot bracket assembly comprising a pivot bracket, a blade and a spring coupling the bracket to the blade.
