<p>The electric circuit protector for road vehicles prevents the untimely discharge of the vehicle battery (1) by signalling by an indicator lamp (4) that a circuit is under voltage when the general contact switch (2) is open. The lamp is connected to the battery via the relay (8) and the switch (2) in one direction and via the circuits to be tested in the other direction. The two circuits (5, 6) with their command switches (10, 11) and anti-return blocking diodes (13, 14) can be left under voltage by the inverter (12) even when the general contact switch is open.</p> |
