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.

Discovered this by accident. I was an electrical fitter in a power station, in Scotland, for 35 years and in the early days we did our own maintenance and repairs on the lifts. This really takes me back. Plc control came in and specialists took over maintenance and all we did, in house, was emergency egress of passengers when the lifts broke down. When we did work on them I remember scratching my head trying to work through sheets and sheets of schematics!

@mrmattandmrchay 4 жыл бұрын

It was the same in the BT (British Telecom) buildings - the relays in the motor room lift logic were very similar to the ones used at the time in the telephone exchanges - so they kept the old lifts running using their own engineers (or so I'm told)

Super-helpful, thank you! Realising that series/parallel switches correspond to logical AND and OR, and seeing how you can make a latching relay circuit, helped me design a scheme for powering a device in a car from the permanent BAT supply using the ACC supply to turn it on but not off (using a separate switch for turning it off).

+Robert Smallwood Many thanks for your comment! I have another video planned to explain COM/NO/NC for beginners. Not sure when I'll make it as I've got other videos on the go, but it's in the pipeline. I always explain things with complete beginners in mind. I've been on loads of training courses where the tutor has "assumed" that everyone was at the same knowledge level, then gone on and on, leaving less experienced people behind. I love explaining and training also. I always think that, if the person doesn't understand what I'm training, then it's up to ME to rethink how I should explain it differently so they do understand.

Good question! The one that I am using to construct the circuit is a DPDT - Double Pole (2 sets of individual switches inside the relay) Double Throw (each switch has 2 contacts, one when it's on, one when it's off). The relay is 12volts. Buying the right relay is the easy bit, generally a 12v DPDT relay will suit most applications, the difficult bit is understanding "what connector does what" on the relay base - some are easy (like 12:01-12:05), some are not marked as clearly as this one is.

its an excellent tutorial, It brought me back to the old Cross Bar electro relay telephone exchanges, if you want to see relays and understand them its mind boggling, the exchanges are full of them, it takes 3 weeks to teach the students on just how to get dial tone which is tracing the circuit from the picking up of the telephone handset to obtaining dial tone, I never did the course as I didn't work in the telephone exchanges, goes to show how smart the technicians had to be, well over my head, unfortunately when the semi conductor was invented and the exchanges used micro processors their knowledge became obsolete.
