A printed circuit board (PCB)-mounted contactor (100, 200) including a PCB (112) with planar surface, source and load terminals (120, 122) fixed to the PCB (122), and a contact. The contact is supported by the PCB (112) 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.
