<p>The present invention relates to a self-testable switching system. It relates to the field of the safety electrical power supply for electrical loads requiring a test function as an electromagnetic clutch engagement. According to the invention, two resistors (Z1, Z2) are arranged at the power supply points (T1, T2) of the electrical load (L). The measurement of the voltages at the points (T1, T2) makes it possible to detect possible short-circuit or open-circuit situations on the controlled switches (I1, I2). Application to the test of on-board systems. <IMAGE></p> |
