The Rule-A-Matic Float Switch is an automatic bilge pump switch that is activated by a float mechanism. If for any reason, your boat should start to take on water, this switch will raise the float and activate the pump. With a limited 1 year warranty and a capability of running pumps (with up to a massive 14 Amp draw), this switch is ideal for any boat.
