Abstract: A method and device for operating a power distribution node can include a controllable switching element configured to switch between supplying a power supply to an electrical load and not supplying the power supply to the electrical load, an electrical sensor connected in series to the controllable switching element and configured to generate a monitoring signal representative of an actual switching pattern of the controllable switching element, and a monitoring controller module receiving the monitoring signal.

Abstract: A method and apparatus for a printed circuit board having a substrate, an electrical component disposed on the substrate and connected to an input, a wire bond connecting the electrical component to an output, and a gas-generating fuel disposed on the substrate proximate to the wire bond to account for an arc fault.

Abstract: A switch module includes a first single-throw switch having a first input terminal 20 switchable to a common terminal. A second single-throw switch has a second input terminal switchable to the common terminal. A first control is coupled to the first single-throw switch and a second control is coupled to the second single-throw switch. The first and second controls are configured to independently control, respectively, the first and second single-throw switches.
