What are these crimping wire connectors called?

I am looking for the wire crimpers for connecting to these buttons: Metal Pushbutton - Momentary (16mm, Blue)

In one of the pictures below, there are what looks like copper crimpers to connect the wires. What are they called? Does SparkFun sell them?

Thanks

I think you’re asking about crimping spade connectors. Se if this helps:
