DC Power Rating for Rotary Switches

[Farley]

The rotary switches I'm finding are specified the current rating at a specific AC voltage.  The application I have in mind would use one pole of a rotary switch to switch 12VDC with a maximum current of 2A. I'm not sure I understand how to determine the DC current handling capability of a specific switch when the spec sheet only specifies the maximum current at AC (usually 120VAC or 240VAC).

Here's a representative specification from the Mouser catalog:

My spidey sense tells me it is more complicated than simply computing total power handling and recalculating for 12VDC.

I wouldn't exceed the AC current rating for the switch. It doesn't say if it is rated for inductive or resistive loads. I would assume resistive and de-rate accordingly for inductive.
