ABSTRACT:
An electronic demand register for an electric meter includes a plurality of pushbutton controls for controlling material displayed or a mode of operation of the demand register. A lockable switch actuator includes an actuating paddle within a cover or housing of the meter which, when unlocked, can be rotated into alignment with a selected one of the pushbutton controls and then pushed inward to actuate the selected pushbutton control. A pair of bosses bracketing one of the pushbutton controls prevents actuation of its respective control until the actuating paddle is accurately positioned between them. A second pair of bosses bracketing another of the pushbutton controls are spaced too closely apart to permit the actuating paddle to pass therebetween and they thus prevent actuation of their respective pushbutton control.
