Two lines crossing, one hopping over the other or plainly crossed.
Also known as: Wire crossover, No-connect crossing, Hop-over symbol, Line jumping another line
Two wires that cross without joining are drawn either with a small semicircular hop or as a plain crossing, and which convention a drawing uses must be known before it can be read: in the plain-crossing convention a junction is shown only by a dot, so a missing dot is a real statement.
Denotes two conductors crossing on a diagram without electrical connection.
Contexts: Electrical equipment
Is drawn either with a small arc hopping one conductor over the other or as a plain crossing, the two conventions being mutually exclusive within a drawing.
Contexts: Electrical equipment
Makes the junction dot load-bearing in the plain-crossing convention: without it, a genuine connection is indistinguishable from a crossing.
Contexts: Electrical equipment
Two straight lines crossing at right angles, one interrupted by a small semicircular arc arching over the other.
