The OP is trying to avoid using a mains-powered relay and wants to use a 24VDC type.

Edit: A 100mA quick-blow mains-rated fuse in series with the bulb would be advisable, to protect the relay if the bulb should fail and arc over.
BTW, the wires going to the NC contacts of the relay aren't necessary (they were used in the simulation of the circuit and I forgot to remove them!)

It would. Or it could go in the relay's self-latching contact path as Eric mentions above.I reckon a N/C switch in the relays coil line would do the trick nicely
The spec for the Schrack 805024 relay you mention says the coil resistance is 475 Ohms. So the coil current is ~50mA. That means the bulb current also will have to be ~50mA, correponding to an 11W bulb or thereabouts. Perhaps as found in a fridge, microwave, night-light, sewing-machine....?What would be the maximum current available to the relay coil with the components shown?
That would have been something to watch....from a safe distance!it was already turned on! WOW did it go!
