This 4-pin replacement switch was exactly what we needed for our RV jack that had been acting up. It fit perfectly and worked like a charm. The installation was a breeze—took less than 10 minutes, even for someone with minimal experience. Our RV jack is back to functioning smoothly, and we couldn’t be happier with the results. Highly recommend this switch for anyone dealing with similar issues!
