Abstract
A leaf-spring switch comprising an insulating switch base having parallel upper and lower arms each having a claw on the inside of its free end, upper and lower leaf springs provided midway between and in parallel with the arms, the upper leaf spring being provided at its one end with a tongue-shaped projection and a first contact and at its other end with a terminal, the lower leaf spring being provided at its central portion with a finger plate surrounded by a U-shaped slit larger in width than the upper leaf spring, the finger plate having a second contact at its one end, the lower leaf spring being provided at its one end with a lug and at its other end with a terminal, the upper and lower springs being fixed by the switch base so that the first and second contacts may face each other, a semicircular toggle spring provided at its one end with a forked part which engages the lug and at its other end with a narrow section smaller in width than the U-shaped slit, and the narrow section of the toggle spring having a slit which engages the tongue-shaped projection of the upper leaf spring, wherein the combined spring forces of the upper and lower leaf springs and the toggle spring make the on-off action very rapid.
