Yes they would work ok provided contacts rating is correct but why not just use a Din rail mounted relay as they have proper clamp terminals and are easy to access and remove.
With relay either put a doide across coil or get the type which have one built in to stop back EMF. I prefer external diode then if it blows I can just change and they cost penny's not pounds like they want to charge extra for built in version.!!
