Switch for a 24V ATX 4-pin connector

Hi all,

I’m new to this, but my first searches in the forum didn’t show up anything I need, so I hope that this is not a duplicate of a previous search. If so, it would be great if you could point me to something useful.

What I need is a switch/relay for a pump that is currently running on a 24V standard ATX 4-pin connector. It’s connected to a software that runs it, but sometimes forgets to switch it, which makes life difficult as it is deep within a running setup arrangment. What I would like to do is being able to remotely switch the pump connector on and off with the help of a relay. Do you have any suggestions on how to do this easily? I have some experience in resoldering etc, but do not see an easy solution for this.

Thanks and best wishes,
Bodo
