Electrical Electronic Control Installation Schematic Wiring Symbols Drawing Template Stencil Engineering Drafting Supplies Layout Plan Circuit Diagram

I purchased this template primarily for drawing waveforms related to power electronic circuits. I found it to be quite useful. One needs to be a bit careful while using and storing this template since, due to the number of punchings in the template, it could easily break if one bends it accidentally. I also think its price is a bit too high - hence, four stars.

I brought this for the contracts manager but cannot find coloured pens thin enough to be able to use on the drawings, although is has all the sign required.
