I have a need for a switch that can handle 28Vdc at about ~1A.
The switches I would like to use have a rating of 24Vdc at 5A.
I would think that the limit of switch is the power, so if we take a switch at 24V and 5A, then it can handle 120W. My reasoning is that a switch can run at higher or lower voltage currents, so long as its less than the 120W (in this case). A 24V 5A switch can be used for a 28V 1A application.
Is the reasoning behind that correct ? Am I absolutely limited to 24V 5A spec'd by the datasheet ?
