EasyEDA is a web-based EDA tool suite that enables hardware engineers to design, simulate, share - publicly and privately - and discuss schematics, simulations and printed circuit boards. Other features include the creation of a Bill of Materials, Gerber and pick and place files and documentary outputs in PDF, PNG and SVG formats.
EasyEDA allows the creation and editing of schematic diagrams, SPICE simulation of mixed analogue and digital circuits and the creation and editing of printed circuit board layouts and, optionally, the manufacture of printed circuit boards.

Step 1: Schematic
Go to easyeda.com,Create a Account and click new project
Click new schematic
Click Parts(In the Left Tab) and Enter Battery in search and select BATTCON_20MM
(You can choose Battery Holder based on your choice) and Click Place.
Click Parts(In the Left Tab) and Enter Switch in search and select SW_08 and Click Place.
Click Parts(In the Left Tab) and Enter LED in search and select LED-805 and Click Place.
Press ‘W’ as connect the component as per the image
Press Ctrl+S to save and Click convert project to PCB (3rd opt after Zoom)
Step 2: Arrange Components
Arrange the components as per the image(Blue lines are called ratsnest) or arrange keeping close to each other(not too close).
Step 3: Autoroute
Click Auto router..(check image)or you can clikc track in PCB Tool and route of your own and Click Run(You can change the parameter as per requirement).See the image, the red lines connecting components are called Tracks
You can add Drill Holes(if you require),By Click Hole in PCB Tool
Step 4: Copper Area/Pour
Click Copper Area in PCB Tool and draw a border on the PCB Board
Save and click Fabrication Output and Download the Gerber Files and sent to your fabricator
