SEAFLO's new product, Electromagnetic Float Switch offers superior performance over competing float switches. The design's enclosure helps eliminate large debris from reaching the switch mechanism, which is the number one point of failure on traditional switches, in addition, its innovative Electromagnetic design uses a mangnetic force to actuate seal failure and water intrusion which is the second most common cause of failure on competing brand's switch. It's unique robust internals also allows this switch to be used for pumps drawing up to 25 Amps. This orginal design makes this the most reliable float switch readily available on the market today!
