Abstract: An electrical test switch has an integral energized circuit indicator. The energized circuit indicator is integrated into the front and/or rear covers of the test switch. The energized circuit indicator is passive and senses properties of the at least one conductor of the device being tested by being placed in proximity of the device. The voltage display provides personnel a visual indication of whether the electrical device being tested is energized without requiring a physical test or direct connection to the at least one conductor of the device being measured.
