Hi - Just brand new to electronics.

I would like to ask for some assistance to identify some objects in a schematic.

Thank you for any assistance.

Here's a pic with the items - the square bars with the red arrows pointing to them.

Ok.
Thanks for the replies.
One more example below - in this pic, the one on the left side has nothing connecting to the points other than the one wire.
What would be the purpose of this connection / terminal?
Thanks again.

Not sure what the schematic is from - I just wanted to start looking at schematics to practice identifying components so I did a quick search online and found a few pics to look over.

So in this case I would imagine then that when the foot switch is pressed it would connect the purple and white wires and complete the circuit?

I see I have a LONG way to go in learning.

Thanks again.
 

They are all 3-pin terminal connectors. However, the last one has a fuse-inline located on the connector. You can physically disconnect/remove the fuse. Hope this help. Check Wago connectors for varieties.
 
Thank you for the reply.

I checked out Wago - don't see too many company sites that are a numerical address instead of a named address - I understand completely now.

Since they have ebooks available to download I am taking advantage of that - love to learn new information.

I'm sure things will start to sink in more easily in the future - the more one learns the easier it all becomes.

Cheers.
