what is the power consumption of the DPST rocker switch that has LED in it?
Welcome to AAC.

There is no way to know the answer to that question with the information you have provided. The power consumption of an LED depends on it’s the applied voltage, the forward voltage, and the value of the current limiting resistor.

Without any additional information I would feel safe expecting it to be ≤20mA.

What? You mean that every illuminated DPST switch doesn't draw the same current? Imagine that.

If only there was some way to find details about the switch. Like a description from the vendor or a sheet with data (it could even be called a "datasheet") from the manufacturer. Even a picture might help.

It only requires the power it takes for your finger to flip the switch from one state to the other. Switches don't draw electrical power. They either conduct or don't.
