12 v rocker switches.

[Engleman]

I have 3-4 12v rocker switches, on /off that are intermittently not turning on light fixtures. They are sigma switches series 201... my rig does sit outside but covered.. can these switches go bad in warmer weather or colder.. I live in a climate to where high temps are usually 90 to 110'. Low temps are rarely freezing.
Just seems coincidental that 3-4 switches having problems. Or are they that cheap!

Might be the bulbs have same corrosion on them. Or the switch is corroded. How old are they. My 1999 switched still all work. I changed all bulbs to LEDs. To use less battery power or ac draw when plugged in.

Its a 2016 that has nothing but LEDs in it.

Have you put a meter on socket to see if 12v when switch is turned on. Might need two people to see. My LEDs might need to flicks of switch if not used for a few months. But after that light every time. Go figure
