@Johns4Y Hi, while the metal tag part does clip off/on (not so easy getting them off without bending them), the switches come as a complete assembly on an easy to replace board. A couple of screws and you can just plug a new switch in no soldering required. I would ask at where you purchased the printer first, see if they will send you a new one free. If that would take too long, a quick search for 'Z end stop switch Ender 3' on duckduck should turn up a lot of hits. They are very cheap (couple of dollars) as a complete assembly.
