B22 bayonet socket

The “B” in the base designation stands for the term bayonet socket. Even if this has nothing to do with the original bayonet, the French weapon, the name does not come from nothing. It does refer to the bayonet catch. It works similarly to the bayonet that was put on the rifle as a stabbing weapon and is defined as a connection between tubular parts that is made by turning and can be easily released again.

A bayonet socket is therefore a socket with a bayonet catch for lamps. Alternative designations for the bayonet socket are swan socket or swan base, after the inventor Joseph Wilson Swan, who together with Edison invented the lightbulb.
