Add HONGFA_HFD2-0xx-x-L2-x Symbol To Relay Libiary

• The symbols are shown in the figure:

• The parameters are configured as shown:

• The package used is shown in the figure:

• Data Book Documentation:HFD2.pdf
• The official web interface:HFD2 Relay
• A note about the pin numbers not matching the values in the manual: there are already packages in the package library that match the dimensions of this part, and in order to reduce the space taken up by the library I chose to use the existing item rather than redraw a new package, so I made the symbols' pin numbers match the packages, which resulted in the symbols' pin numbers being different from the values given in the datasheet.
• An unanswered question: I found a 3D model of this part on the HONGFA website, and it just so happens that the 3D model of the library package I'm using is missing, should I use it? Will there be any copyright dispute?
