Your bilge pump's been running late or not at all, and the enclosed float on your old switch has corroded out. The Rule-A-Matic 20A steps up to 20 amps at 12V with a sealed, enclosed float that won't let saltwater eat it from the inside. Handles 24V systems without breaking a sweat. Drop-in replacement for the standard MPA310 when you need the extra current headroom. Add to cart
