Editing Defensive design (section)

Many [[electrical connectors]] apply this principle by being asymmetric.
Alternatively, [[USB-C#Ease_of_use|USB-C plugs]] are mechanically but not electrically symmetric, but achieve an illusion of symmetry resulting from how devices respond to the cable, and hence can be plugged in either of two ways. Accompanying circuitry makes the plugs and cables behave as though they are symmetric.
