It's to switch DC.

It would take a true optimist to guarantee a solid state relay will have a
longer life than a traditional one.

I shifted an application from octal base conventional relays to these
because of relay failures, and these have been far more reliable
(although not completely infallible).

Well remember the first SS relays I was aware of. Used to switch the 'on
air' lights in a newly refurbished TV studio. Hardly a day existed where
they all worked. ;-)
