Special Switch: Find the Perfect One

Hey everyone, so I have two cables, both carrying 12V. I'd like to put a switch in between them. I could just use two separate switches, but I'd prefer to use only one since they always need to be on at the same time.
Google hasn't been able to help me so far. I'm not even sure what to search for. Does such a switch even exist?

Best regards,
Rene.
