Need confirmation from you wise and far more knowledgeable people please. i am thinking of using these switches Oval Neon Rocker Switch 220v Amber | Rapid Online in my boat switch panel. I am using a 12v 200AH leisure batter would these be ok to use? not going to blow etc, i don’t think they will but need some support please.
Switches specified with AC current ratings only are not suitable for switching other than low current DC. generally there are 2 problems, a) the arc created at the time of switch opening tends to destroy the contact face. On AC there is some degree of arc self quenching as the cycle voltage decreases. b) without suitably designed DC rated contacts, there will be no self cleaning action resulting in pitting to one contact and a peak forming on the other and the build-up of resistance due to oxidation.
In a marine environment you'd be better buying suitably rated swirtches
