We do it every day. We push the button, the lock of the gate or door opens and we leave home. We don’t normally try to understand how the mechanism works, we are only interested in the fact that it does work. But when something fails, or when we need to buy a new lock, it is important to understand how things work, so you know what to do or what to choose.
In this short video we see what happens inside an electric lock for pedestrian accesses when the electrical pulse is given or the key is turned.
