In its relaxed state, the “STBY” legend of the LED indicator is illuminated since the SPDT-DB switch is providing a path to ground through the normally-closed (NC) position of the switch contact. When the pushbutton switch cap is pressed, the SPDT-DB switch is actuated and latches in the normally-open (NO) position. This provides a path to the sense input of the NEXSYS® Current Sensor component. The "ACTIVE" legend remains Not Energized until the sense Input of the current sensor detects current above the specified set point. When this occurs, the Z output sources a Ground to Energize the "ACTIVE" legend, indicating that the specified current set point is reached.
