Troy David, VP of Keystone Electronics, keeps his ear to the ground for new ideas—literally. Recently, he noticed that more engineers were asking for terminal screws colored green (presumably to denote ground). Keystone offers several styles of terminal screws, which it says is an economical alternative to PC screw-type edge connectors. The screws normally come only with an unpainted finish. Though companies typically silk screen the name of the type of connection on to the circuit board, David surmised that some engineers use the colored screws as a quick visual check. So now he's offering a whole rainbow's worth of color-coded terminal screws, including green, black, blue, yellow, and red. Instead of plating the brass screws with tin plate, engineers will apply a zinc plating and a chromate conversion coating, which absorbs the dye. Keystone plans to offer the color-coded screws as a standard product this coming Fall, and is currently providing sample quantities to engineers.

California’s plan to mandate an electric vehicle market isn’t the first such undertaking and certainly won’t be the last. But as the Golden State ratchets up for its next big step toward zero-emission vehicle status in 2018, it might be wise to consider a bit of history.
