Circuit arrangement of an electric torch in particular of that used for inspecting electric wiring equipped with two lighting circuits powered from power sources of different voltage levels and an auxiliary circuit powered from a lower voltage source characterized in that one pole of the output (11) is connected via the contact (9) of the breaker switch (10) with one pole of the higher voltage filament (7) in the two-filament bulb (5), and the other pole of the higher voltage filament (7) in the two-filament bulb (5) is connected via the contact of the breaker switch (8) with the other pole of the output (11) with the contacts of the breaker switches (3 and 14) remaining open, whereas with the contacts of the breaker switches (3 and 8) one pole of the output (11) is connected via the contact (13) of the breaker switch (10) with one pole of the lower voltage source (2) and the other pole of the lower voltage source (2) is connected via the lower voltage filament (4) in the two-filament bulb (5) and the contact of the breaker switch (14) with the other pole of the output (11).<IMAGE>
