DEFINITION

Classification: 439/220

Lamp or electron tube socket or base:

(under subclass 218) Coupling part particularly adapted to detachably receive and electrically couple to a member

intended to radiate light, or to a member including electrical, amplifying or switching means utilizing an environment excluding vacuum maintaining envelope; or comprising the electrical connector of such a light radiating or switching member.
