Abstract
An electrical snap-action switch has as its moving member a strip (15) of a springy metal with which there is integrally formed a contact-carrying arm (18). This strip is held bowed into a C shape in a metal carrier (10) with a concave inner face (11) near which the strip lies when in one position. The operating member of the switch is a rocker (23) of an insulating material which rocks on a convex "bump" (24) on the carrier so that it has an inwardly extending pillar (24) with two studs one on each side of the strip (15). Hence operation of the rocker snaps the strip between its two positions, with corresponding movement of the contact carrying arm.
