Abstract: A control box includes a housing in which is pivoted a control lever having an aperture in its lower arm. The bent end of the core of a flexible cable is hooked into the aperture operatively to connect the control lever and the cable core. Swaged upon the cable casing is a cable hud having an annular groove fitted into a part-circular slot in the rear wall of the housing.

Abstract: A locking system is described for detachably securing two workpieces together (e.g., two housing sections). Elongated arms are carried by one workpiece and a corresponding opening(s) is present in the other workpiece. The outer end of each elongated arm is resiliently deflectable so that it is deflected when being inserted into the opening in the one workpiece; then the arm springs back. A locking arm on the second workpiece is then able to move behind the end of the elongated arm to restrict deflection of the arm, thus preventing any unintentional unlocking of the two workpieces.
