Horn switch question

[oldirish]

I have a 72 Duster 360 Magnum with 518 OD transmission that I'm trying up loose ends on

The horn works but the Horn button and switch assembly is incomplete.

The cap I have had a circle of snap ribs on the center that looks like it would fit the switch assembly attached.

Can anyone confirm this, I need to buy one of the switch assemblies

Thanks

You don't need the spring with that horn assembly. There are three small springs built into that switch assembly.

Great, thanks for the help.

So the prongs on the cap snap into the round hole in the adapter?
