Electric Plug with Switch – Innovation

I Invented a Switch Plug in my school days but venture capitalists were not invented yet.

From Creations

This idea struck me when i used to visit flea markets to collect gramophones and calling bells and some chemistry lab flasks and test-tubes too. Electronics had not come to me yet and not much in the flea market in those days except a spool player or valve radio (tape recorder). I used to see that the electric plug was a popular item sold in the carts outside the flea market. This was some feature i thought would give me competitive advantage. I will do it one day.
