On a boat, with a 12v DC system, I want to wire a switch between a solar panel and the MPPT controller - I want to use a small, low profile LED switch which claims to be rated at 12v/25amp. But my 175watt solar panel has an open circuit voltage of 21.6 (operating voltage 18v) which means I am pushing about 9amps (max) at 18v - is that safe for a switch rated to handle 25amps @ 12v?
