JAK UZALEŻNIĆ ZWROTNICĘ ELEKTRYCZNĄ W URZĄDZENIACH MECHANICZNYCH ?

Some might be a bit surprised by what it takes to not only shift a switch, but also, and more importantly, lock it in place in mechanical devices. I've already covered some of this material when I discussed how an electromagnetic lock works. As a reminder, here's the link:    • JAK DZIAŁA ZAMEK ELEKTROMAGNETYCZNY ?   However, I demonstrated this using a modern lock. Here's an older model of an electromagnetic lock with a key lock, which are used, among other things, to lock a manually shifted switch. See for yourself how it works :) @MichalPiatkowski
