You are more likely to get a proper response if you asked a Question, rather than making a statement.
In a Forum, including CR4 Forum, good manners are also helpful, a please and/or thank you will often assist in your receiving a good response.
However, since it appears that English could not be your first language, I shall overlook the deficiencies in your un-asked Question (Statement), and re-phrase what you said:
"Could you please advise a website which shows all electrical symbols, thank you."
Just to explain: You could have done what I just did for you, use an Internet Search Engine.
In Google: Results 1 - 10 of about 355,000 for allelectricalsymbols. (0.19 seconds), and the two above weblinks are among those on the first of the "about 355,000 webpages" which have those search words on them.
Get familiar with using Internet Search Engines, they are free, and give you fast access to the World's largest Library: "The Internet".
I trust you now feel assisted.
Kind Regards....

The standards organisations that regulate the current "standard symbols" seem be run as money making enterprises. So to get the symbols you need can cost serious money. I'd suggest you check out your local university library first.
