Oh, I'm so happy about this one! Taking you in close and intimate with one of the very same switches that populate the Apollo Era Mission Control consoles. Enjoy!

I saw this 2 years ago and just had to come back here. I used a number of these switches in the mid-70's in my electronic hobbyist craze. I used them to make an illuminated control center for my stereo system and speaker switches with relays. I got these at electronic surplus places in Minneapolis, one was Honeywell Surplus. This vid brought back a lot of memories
Great thumbnail. Thanks for your work on YT.
ah. teeter-totter means a see-saw, i just looked it up. i always thought it was something to do with potatoes that American children ate in school lunch.
edit- i looked the potato thing up too. i was thinking of tater tots, that's what Americiums called potato croquettes.

My aunt worked at North American on Apollo and there was tour for families. Her and I went and was quite a thrill for me as elementary school kid. Also later now in high school brother had small garage trophy biz and got job from probably JPL for crew awards for 1st step on moon. He was given pre-printed plaques to attach. Everything said was scripted at that time and there was a misquote leaving out the "A". Told him he should hang on to one of the plaques but said he was told he HAD to return them ALL and then was provided new plaques with the corrected wording.

Hell yea! hook that thing up! :p how could u Not use it in something special lol obviously something it wouldnt get actuated too often.. but still seen also i was checkin out ebay, u can get replacement parts or the whole switch if u want n on top of that theyre not crazy expensive
lol its got a dedicated msc part # :p
These switches were also used in power plants built in the โ70s. They were used in early multiplex equipment. Useful for operating remotely located equipment. Ours was replaced after 30 years when the spare parts were hard to find in the primary market.
You can buy cheaper modular switches like this from China today. They have the lamp in the front part and the switch module clip at the back. So tech from the Apollo days is still being used today.
You often show a lot of items that were made in the USA. Seems they have to date back pretty far to enjoy that status.
I had no idea that these were special. My dad used to buy them at state surplus by the boxful. He even used them all over the dashboard of a kitcar he built in the early 70s. I now have his boxes of them, LOL. He taught me how to open and service them, change bulbs, etc. Some are momentary, some latch. I love that you got one of them (if I had only known you were looking) ๐
Fran, you are AMAZING!! I just discovered your channel and you have already blown our minds with your incredible videos about the Apollo launch vehicle ejectable film canisters, the F1 engine design, and the brain-bending design of the Mission Control video displays, and right now we are watching your exploration of the Mission Control panel switches. You have made my day!! What a terrific communicator you are!!? Your extraordinary knowledge and enthusiasm are as infectious as they are impressive. Congratulations!!! My wife works in science education here in Australia and she is definitely recommending your channel to her colleagues at her school. Hats off! You are my new favourite YouTube channel and I'm already getting RSI from sharing your videos to my friends! Love your work, and so excited to explore all your wonderful videos. Live long and prosper!
Other than bulbs (327), I don't recall replacing parts of the switch. Remember replacing the entire switch assembly. Depending on the switch, a rather laborious job at times. The harness' were exquisitely hand wired. KSC Test Conductor Units were huge by today's standards and loaded with those switches. Eventually Shuttle brought in new comm systems and eventually all Apollo era (and before) equipment was replaced. I do remember the last units replaced may have been the audio 4-Wire comm panels.
I used to have one of these mounted in a 1U rack with several multipin connectors on the back. It had come from the British Broadcasting Corporation central control room in London, England. It lit up red or green and would have been pressed in the event of an imminent nuclear attack. It rerouted every BBC transmitter in the world to their emergency operations bunker in central England via circuits which did not pass through London, and would have allowed broadcasting to continue if London was destroyed.
When I was in high school, we had TONS of these in our electronics and robotics classrooms, all new in box. They were most likely donated from Rockwell, Allied Signal, or Bendix in the 80s…
I helped take most of them to dumpsters when the school was remodeled in 1996. We had no idea just how special they were!
Used the same switch in the Air Force on the cargo aircraft test equipment.
Korry switches are some of my favorite electro-mechanical devices. My simulator was full of them.
