Micro Switch Amp Rating

I think you are going to have to contact the vendor for the information you want. DC has it's own set of peculiarities. The current rating many times depends on what the load is. If it's a light (resistive) a switch can handle more current. If it's a coil (inductive) the current rating drops. There is just no way I know of to predict what the 12 volt DC rating would be based on the listed ratings. As a note, the switch you have pictured is obsolete and no longer a sale item.
