The pins on Type A and Type B plugs have a hole near the tip that fits into ‘bumps’ found on the contact wipers of some sockets, so that the pins are gripped more tightly allowing for better contact and also to prevent the plug from slipping out of the socket. Some sockets have spring-action blades that grip the sides of the pins, making the holes obsolete. |
