    I found these all together in a drawer in the basement where I work. What are these items and what can they do together?

    Oh particularly those 2 items in the top left. Those are the same item. They seem like some sort of relay. There are moving parts and and metal leads just aaaalmost in touching contacts.

    Are you? That's great!
    Anyways, I know you guys can't read the part numbers. I was hoping the collection would ring a bell with someone. I googled the number written on the "relays" and nothing came up. I can post the part number if you guys want though. Also, I know that one is a fuse. Thought maybe it's inclusion might help. There was a TON of each of those parts in 1 drawer. They gotta be part of a set....
    Also, this part was with them:

    All parts say "NEC" inside a diamond shape.

    A guess that the one on the left is a 100nF capacitor.
    The lower 'diode' looks like a wire wound on a ferrite bead to give a certain, possibly lossy inductance.

    not sure how you got that ? .... that would be more likely for the top example :)

    I have seen old diodes encapsulated like that ...
    the one end flat, other end curved indicates the polarity :)

    You guys are BETTER than google. Can you imagine? Google had NO idea.

    Are these antique parts? Is that lamp pre-LEDs? It's odd that I can't google those part numbers.

    So, here's both sides of that part. It's on the far left. To it's right are similar parts I found with it.

    Not that the hole in the middle of the part on the left is threaded.

    Thanks guys!

    I see a copper wire around the device so thought it would be a ferrite bead with the wire passing through twice. A closer look seems to see a fine wire wrapped around the RH lead but not soldered. Quite a conundrem, try a magnet to see if it is ferrite.

    @Pharaday Please use a more specific title for your posts. You currently have 2 separate threads both titled "What are these?". This is confusing.

    My guess (if you're taking guesses) is parts out of a old radio/communications or radar system.
    That lamp davenn pointed-out is called a 'slide base' lamp, the voltage and amperage is usually stamped on one side of the silver contact side-contacts, sometimes the actually part number.
    I'd estimate their age as 1960s or 1970s vintage.
    You might find a use for the small components, but the larger ones are for a specific system of that era.
