Abstract of the Disclosure An actuator assembly for operating a hook switch in a telephone set includes an actuating member with a cantilever leaf spring. The actuating member is pivotally mounted to the inner surface of the cover and is biased toward the inner surface of the cover by the cantilever leaf spring. In the absence of a handset the, actuating member partially protrudes through an aperture in the cover into a cradle formation. Placement of a handset into the cradle formation pivots the actuating member away from the inner surface of the cover to actuate the hook switch. - i -
