Abstract

L'invention concerne un circuit de vérification de continuité de fils électriques. Elle se rapporte à un circuit dans lequel deux lampes NE1 et NE2 s'éclairent ensemble ou séparément, lors de l'enfoncement d'un commutateur SWA, SWB, selon que les fils de phase, de neutre et de masse sont bien connectés ou présentent des connexions erronées de diverses manières. Application à la vérification de la continuité des circuits de masse.The invention relates to a circuit for checking the continuity of electric wires. It relates to a circuit in which two lamps NE1 and NE2 light up together or separately, when a switch SWA, SWB is pressed, depending on whether the phase, neutral and ground wires are well connected or have wrong connections in various ways. Application to checking the continuity of earth circuits.
