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.
