How an elevator FLOOR SELECTOR works

When you travel in an old elevator - the FLOOR SELECTOR is the device that "keeps track of where the elevator car is", before microprocessors were around. It's normally mechanical and interesting to watch - watch the movie to see some! There are some weird and wonderful devices here, but the one that I'm going to explain in detail is the OTIS design. ..........

THE MRMATTANDMRCHAY CHANNEL, established 2008: I'm passionate about uploading quality and interesting videos for YOU, my audience. What is my channel about? "Old lift machinery made interesting", old air-raid sirens, prehistoric alarm equipment. If "I" don't find it interesting ...then IT DOESN'T GET UPLOADED! I always spend a lot of time editing my videos with animations, video in-sync with music and voice overs to make them this way. My moto - "Quality NOT Quantity" - spending a month editing a video is not a rarity! But without you, I'm nothing here. Thank you so much for watching. ...mrmattandmrchay is me (Matt) and my son Chay. THANK YOU very much for watching :)
