A professional 2D electrical schematic diagram of a control circuit, clean engineering layout. 2D vector graphic style, flat design, white background, solid black lines, minimal and modern electrical chart. Top-down logical flow using standard industrial electrical symbols. The diagram is a single vertical sequence of block elements with precise arrow connectors pointing downwards. From top to bottom, the blocks are labeled with crisp black typography: "[ Ввод цепи управления: Фаза L / ~220 В ]", followed by an arrow to "[ SF1: Предохранитель цепи управления ]", followed by an arrow to "[ Кнопка "СТОП" ]", followed by an arrow to "[ Кнопка "ПУСК" ]". Parallel to the "START" button, a bypass line loops around featuring a normally open contact symbol labeled "[ Контакт НО КМ1 ] (Самоподхват)". Below the button, the sequence continues downward with arrows to "[ Контакт PSL-01 (Ридан KPI 35) ] (Размыкание при сухом ходе)", then to "[ Катушка контактора силовой цепи КМ1 ]", and finishes at the bottom with "[ Ноль N ]". No 3D shading, no realism, no colors, pure flat monochrome CAD style diagram, high readability, isolated on white background, professional technical documentation standard.
