Deep Space 1 tested a power actuation and switching module (PASM), the result of a joint development among Lockheed Martin, Boeing, and JPL. This device contained two sets of four power switches. High-density packaging technology quadruples the packing density over the current state of the art.

These switches can actually report to the spacecraft�s computer on how much current and voltage they are switching. Regular tests showed that the performances of both PASMs were consistent with prelaunch tests.
