Finding connectors for push button component What type of connectors would I use for these buttons?:

They sell wires with the connectors already crimped on, but I only need the connectors.

I found https://www.jameco.com, but i'm not sure which connector would be right, or what to look for specifically.
Go down to your local (decently-stocked) hardware store and ask for "quick connect terminals". From the dimensional drawing you'll need 2mm or 5/64" terminals.
