Visio Electronics - 721 Visio shapes and symbols in 39 Visio stencils (in both US units and metric units, all in Visio VSS, VSSX and VSDX formats) for creating your electronic circuit diagrams in Visio. Below are some sample shapes for you to download and try out. Most of the shapes have custom properties (ShapeData) for manufacturer data, part numbers etc. so that you can create BOM (bill of materials), parts lists and inventories using the standard Visio report tools.
Push buttons, relay contacts and switches have an action on their right-click menu to swap between open and closed contacts (and the switch moves - you can use this to animate the switches).
All shapes have connection points at suitable locations. Use the standard Visio connector tool or any connector from the connectors stencils to join the shapes.
If these are not the shapes you want then maybe you want Electrical shapes.
The stencils included in this collection are: abstract electronics, automotive devices, capacitors, computer parts, connectors, data bus and registers, devices, DIN connectors, diodes, electro-mechanical, electronics, extra logic gates, flip-flops and latches, IEC logic gates, inductors, instruments, ladder - PLC, laser sensors, logic gates, miscellaneous, MOSFETs, op-amp building blocks, opto-electronics, power semiconductors, power symbols, radio, resistors, RFID, signal sources, timing diagrams and waveforms, transducers, transistors, vacuum devices.
