I agree that switching DC is harder but as I said a 120 volt AC switch will not have a problem with 12VDC... At least not at any current you are likely to encounter save on the power leads to an inverter and likely not even then.
It has to do with the 10 to one (Really 14 to one) voltage difference.
Every switch is rated both AC and DC volts and current. Just not all publish the DC ratings. . I used a standard AC switch for the porch light on my Scamp. the actual light was an automotive headlamp cartridge type (Modern) one element was bad (Likely the low beam) so I wired it up and put it in a Jelly Jar Porch light that I hung on the side of the Trailer and plugged into a 12 volt accessory outlet. that is about a 30-50 watt lamp. Most porch lights are 25 or less.
