One question: My 12 volt switch for the absorber fridge (a 20 year old electrolux) always burns. I bought a switch for 20A that should be enough. But it doesn’t. Sometimes it’s good for half a year, sometimes 2 months. What can the lying down? Actually it has to be an over-gan resistance to power is not set. In addition, a battery monitor is installed, which interrupts the power supply in cloudy weather (solar on the roof) and prevents it from operating. So it can happen that the current is switched on in the minute. (but of course not from the switch that always burns) Maybe that’s important.
