    FunctionPossible function: Multiple screw terminals can be arranged as a barrier strip, with each short metal strip having a pair of screws. This is used for connecting two different components, one on each side of the pairs. This arrangement is common in luster terminals. Terminals can also be arranged as a terminal strip or terminal block, with several screws along (typically) two long strips. This creates a bus bar for power distribution, and so may also include a master input connector, usually binding posts and/or banana connectors.
