Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
205 words
A control actuator for an electronic demand register for an electric meter, said electric meter having a transparent cover thereon, comprising: at least first and second pushbutton controls disposed in a pattern on said electronic demand register within said transparent cover; an actuating rod extending through said cover; an actuating paddle affixed to an inner end of said actuating rod; said actuating paddle having a width; lockable means at an outer end of said actuating rod external to said cover, said lockable means including means, effective when locked, for preventing actuation of any of said at least first and second pushbutton controls; said lockable means further including means, effective when unlocked, for selectively permitting rotation of said actuating paddle into alignment with a selected one of said at least first and second pushbutton controls and for permitting inward actuation of said actuating rod and said actuating paddle toward said selected one; first and second bosses disposed at a spacing from said first pushbutton control; said first and second bosses having a height exceeding a height of said first pushbutton; and said spacing being less than said width whereby said actuating paddle is prevented from entering therebetween and actuation of said first pushbutton control is prevented.
Claim 2
Dependent Claim
205 words
A control actuator for an electronic demand register for an electric meter, said electric meter having a transparent cover thereon, comprising: at least first and second pushbutton controls disposed in a pattern on said electronic demand register within said transparent cover; an actuating rod extending through said cover; an actuating paddle affixed to an inner end of said actuating rod; said actuating paddle having a width; lockable means at an outer end of said actuating rod external to said cover, said lockable means including means, effective when locked, for preventing actuation of any of said at least first and second pushbutton controls; said lockable means further including means, effective when unlocked, for selectively permitting rotation of said actuating paddle into alignment with a selected one of said at least first and second pushbutton controls and for permitting inward actuation of said actuating rod and said actuating paddle toward said selected one; first and second bosses disposed at a spacing from said first pushbutton control; said first and second bosses having a height exceeding a height of said first pushbutton; and said spacing being less than said width whereby said actuating paddle is prevented from entering therebetween and actuation of said first pushbutton control is prevented.
Claim 3
Dependent Claim
89 words
A control actuator according to claim 1 wherein said means, effective when locked, for preventing actuation of any of said at least first and second pushbutton controls includes a stationary member affixed external to said cover, a hole in said stationary member, a pivoted actuating arm affixed to an outer end of said actuating rod, and a corresponding hole in said actuating arm alignable with said hole in said stationary member for permitting the locking of said actuating arm to said stationary member by a lock element passed therethrough.
Claim 4
Dependent Claim
71 words
A control actuator according to claim 1, further comprising: third and fourth bosses disposed at a second spacing about said second pushbutton control; said third and fourth bosses having heights exceeding a height of said second pushbutton control; said second spacing exceeding said width whereby said actuating paddle is enabled to pass therebetween for actuating said second pushbutton control after said actuating paddle is aligned between said third and fourth bosses.
