Abstract
A unitary combination actuator and indicator flag for an electronic energy meter. The integral actuator and mode indicator is slidable within the bezel of the meter and in the off position is not visible. Sliding the actuator simultaneously moves a camming surface over an axially moveable switch to connect the meter test mode, and slides a visible "TEST" flag over the digital readout window to indicate that the watthour meter is in the test mode. Positive actuation and positioning members are included for both the off and on positions.
