Wire spring relays can be fixed if the damage is minimal. Did the contact card get smashed, or did the wire springs get mangled? Or both?

Which relay got damaged? Can you take a look at the BSP for the 236 and some BSP's for other KTU's and see if there is a suitable replacement on a less-rare unit?
