How to read it

The two bars are the pause symbol. IEC 60417-5111, “pause; interruption”, is defined for the control that interrupts the run of, for example, a tape, while the drive mechanism keeps turning. Unicode encodes it as U+23F8, the double vertical bar, and a triangle beside the bars, U+23EF, is the play/pause toggle found on a single button.

Where the bars came from

Nobody has pinned down where the pause bars came from, Jason Kennedy wrote in The Conversation; he notes they look like the caesura, the mark for a break in poetry and music. Gizmodo in 2010 listed other suggestions, the symbol for an open connection in an electrical schematic and a stop square with its middle cut out, before settling on the caesura too.

Look-alikes

The filled square is stop.
