Achieve professional-grade technical accuracy in your electrical schematic designs. This specialized drafting tool allows you to translate complex circuit logic into clean, standardized visual diagrams with the reliability required for industrial and residential electrical planning.
Precision-Engineered Schematic Drafting
You need symbol consistency to ensure your electrical control layouts are readable and professional. The STAEDTLER Mars 977 153-02 eliminates the guesswork by providing standardized symbols for switches, coils, and relays in a compact, durable format.
Integrated riser pins on the reverse side lift the template off the paper, preventing technical pen ink from smearing during movement.
Comprehensive set includes standardized industrial symbols for contacts, coils, and switches essential for control panel design.
Precision die-cut edges optimized for 0.5mm mechanical pencils and fine-liner technical pens for repeatable line work.
The matte-processed surface reduces harsh studio light reflections, allowing for comfortable long-term drafting sessions.
Technical Fit and Durability
Constructed from dimensionally stable, flexible green plastic, this template maintains its accuracy over decades of heavy use. Its compact 5" x 7-3/8" footprint makes it an essential addition to any portable technical drafting kit or professional studio desk.
