ABSTRACT:
An electronic energy meter is provided with a plurality of push button switches on the face of the meter which are selectively actuated by an actuator extending through the transparent cover to display various different meter functions. Switch restrictors are removably provided around a section of the actuator of selected switches which may then be readily actuated only from the inside of the meter, after unlocking and removing the cover.
