Hi all.
Hope you can help me out.
I'm making a battery powered electronic cigarette and I need a momentary switch that is rated above 20amps at 8,4v. There tons of switches out there but the ones I like are rated at 3A/250VAC or 2A/ 36V DC etc, do these switches have a higher amp rating if the voltage is lower or is this the maximum amps no matter the voltage ??
My next question would be if the switches can take more amps the lower the voltage how do I calculate the amp rating at certain voltage??
Example switch:

Thanks
