These two little holes help the plug stay more firmly in place. A raised part within a standard electrical outlet usually fits perfectly into these holes, allowing the plug’s prongs to make better contact with the metal strips inside the socket.
Securing the plug ensures constant contact with the power source. These round holes also prevent kids from tampering with the outlet, exposing them to danger.Many round-pronged plugs may not fit securely into outlets, leaving a piece of the prong exposed, which can be hazardous to young children. If you have young children, it is recommended that you utilize flat-pronged plugs with holes.
Manufacturers frequently use the two holes in the prongs to attach seals, allowing buyers to distinguish between new and used items. Furthermore, despite their modest size, these two circular holes allow manufacturers to save a significant amount of steel, especially during major manufacturing processes.
