Abstract: A system includes a mechanical switching device having a first moveable contact operatively connected to selectively contact a first static contact. A second moveable contact is operatively connected to selectively contact a second static contact that is electrically connected in parallel with the first static contact. The first and second moveable contacts are mechanically connected to each other to move between a closed circuit position and an open circuit position. The first moveable contact contacts the first static contact before the second moveable contact contacts the second static contact as the first and second moveable contacts move into the closed circuit position from the open circuit position. The first moveable contact disconnects from the first static contact after the second moveable contact disconnects from the second static contact as the first and second moveable contacts move from the closed circuit position into the open circuit position.

Abstract: A transistor module assembly includes a longitudinally extending load bus bar, a longitudinally extending feed bus bar parallel to the load bus bar, and at least one transistor package operatively connected to the load and feed bus bars. The transistor package includes a drain surface and a source lead. The drain surface is operatively connected to the feed bus bar for receiving current therefrom. The source lead is operatively connected to the load bus bar for dissipating current from the transistor package to the load bus bar.

Abstract: A printed circuit board (PCB)-mounted contactor including a PCB with planar surface, source and load terminals fixed to the PCB, and a contact. The contact is supported by the PCB and is movable between open and closed positions. Movement of the contact is parallel to the planar surface. Electrical assemblies having PCB-mounted contactors and methods of controlling current flow in electrical systems with PCB-mounted contactors are also described.

Abstract: A power distribution controller includes a solid state power controller (SSPC), a power system, and a backup power system. The SSPC is configured to selectively deliver a first power from a first power source to at least one electrical load. The power system is in signal communication with the at least one SSPC. The backup power system includes a first output in signal communication with the SSPC and a second output in signal communication with the power system.
