I am searching for a power relay to switch between two 24V power supplies. Currently I use two separate 5V relays switched on from the same digital output.

something like this

I looked in RS and Mouser but am not able to find anything useful. Since there are footprints available I guess such relays exist and hopefully for my requirements.

  • I tried a similar question in electronics exchange and it was closed for the same reason

  • Hm, interesting, not sure why they wouldn't have taken it. I still think it's off topic for this Stack Exchange though. I am glad you got an answer though.

You are looking for a DPDT (double pole, double throw) relay. This has a schematic like this: RT-1-DPDT-8A

You can find such relays in stock at multiple suppliers, though I highly recommend digikey. Here's a list of 5V DPDT Power Relays with over 2A:

Digikey.com - 5V DPDT Relays (through hole)

Mouser.com 5V DPDT

  • Thank you. Without the right keywords it was hard to find the parts
