How to use a circuit diagram template.
- 01Choose a starting point
Open the circuit diagram tool and select a blank canvas or start from one of the dual power selector examples below.
- 02Add power sources and switching elements
Place two input power symbols (battery, adapter, etc.) and insert the selector mechanism—diodes, MOSFETs, or a relay—along with necessary resistors and capacitors.
- 03Connect and label the circuit
Draw wires to establish the power path, add labels for inputs, output, and control signals, and include component values if needed.
- 04Customize appearance and annotations
Adjust colors, line styles, and add text notes to highlight switching logic, thresholds, or status indicators.
- 05Export or share
Download the diagram in your preferred format (SVG, PNG, PDF) or share a live link for collaboration.
Questions about circuit diagram templates
What is a dual input power selector circuit?
A dual input power selector automatically routes power from one of two input sources to a single output, typically based on voltage levels, availability, or manual control. It ensures uninterrupted power by switching to a backup source when the primary fails.
What are common implementations of dual power selectors?
Common methods include diode OR-ing (simple but with voltage drop), MOSFET-based ideal diode controllers (low loss), and relay or mechanical switches (for higher power or isolation). Each has trade-offs in efficiency, cost, and complexity.
Can I simulate the selector circuit behavior?
The circuit diagram tool focuses on drawing and documentation rather than simulation. However, you can clearly annotate switching conditions and expected voltages to convey the circuit's operation.
Are the example diagrams editable?
Yes, every diagram in the gallery is an editable template. Click on an example to open it in the editor, modify components, and adapt it to your specific power requirements.
