A rapid low voltage testing apparatus for detecting sequentially a plurality of electrical components of an electrical circuitry device for at least one of a plurality of predetermined low voltage levels. The rapid low voltage testing apparatus comprises a first multi-position switch having an output for sequentially outputting one of a plurality of input voltages; and a second multi-position switch having an output for sequentially outputting one of a plurality of predetermined output voltage levels which adjusts the sensitivity of a voltage detection circuit to the one of the plurality of predetermined output voltage levels. Upon a detection of a match between the first multi-position switch output and the second multi-position switch output, an indicator notifies the operator of the testing apparatus that one of the plurality of low voltage levels has been detected.
