The easiest LATCHING RELAY CIRCUIT to understand ever! Both theory and practical explained.

I love relays! They are easy to understand, you can see them working and they are still in use today in many many systems to switch voltage into circuits to make things happen!
In this tutorial, I explain from VERY BASIC terminology of a simple light bulb circuit to how to create a "latching relay circuit" and it's purpose in life!
I relate a lot of this to older generation LIFT/ELEVATOR systems which uses latching relays.
I hope this video makes sense, and sorry to all the more experienced electronics users explaining a "battery-switch-light bulb" circuit, but I always START AT THE BASICS so that everyone can understand it.

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 :)
