Opto coupler

Hi, i want to know why i can not use opto coupler or opto triac to control main 230 VAC directly without using any external triac. I search on Google many times to get the answer, but all the best answers i found that is opto isolator controlling the triac and the triac controlling main voltage. In my project, i want use only one part either opto isolator or triac. Thanks

Go ahead - I’ll recommend you for a Darwin award http://www.darwinawards.com/

Use a solid state relay. Opto's are not designed for this use as they are very low power.

I strongly advise you to not tamper with 230 V mains voltage unless you know what you are doing. If you aren't sure, you don't know.
