A simple circuit at first. One line with a NO PB through a NC PB to a relay.

PB left aligned
Relay right aligned
NC PB unaligned

Consider ideal spacing between components and left/right extents.
Also keep in mind how to implement AND within circuit for next step of drawing a simple latching circuit.
Components should be drawn by alignment left->none->right in order they were added.
Raise exception for now if total circuit length would exceed left and right borders.
