@joeyh 🔌 ("ELECTRIC PLUG") maybe? U+1F50C from Unicode block https://en.wikipedia.org/wiki/Miscellaneous_Symbols_and_Pictographs
It has some semantic meaning compared to the generic ⚇ ("WHITE CIRCLE WITH TWO DOTS"). Though rendering depends widly on the font used.

Unfortunately, there doesn't seem to be any Unicode representation for a defined representation yet (such as https://www.iso.org/obp/ui#iso:grs:7001:PI_TF_044 ) .
