Common Concerns Answered
Is the 15A amperage limit sufficient for my high-draw bilge pump?
The Johnson Pump Electro Magnetic Float Switch is rated for a maximum of 15 amps. If your bilge pump's operating current exceeds this rating, you will require a float switch with a higher amperage capacity to prevent premature failure. Consider the Rule-A-Matic Plus Float Switch 35A for higher amperage applications.
Are there any reports of this float switch failing over time?
While the vast majority of users report excellent reliability, there are occasional instances of switch failure reported after extended periods of heavy use. This is not a widespread issue, and the switch's robust construction and encapsulated electronics are designed for longevity in marine environments.
How does this switch compare to other float switches in terms of reliability?
This Johnson Pump float switch differentiates itself with integrated false start prevention and encapsulated electronics, offering enhanced reliability and protection against common failure points found in simpler designs. Its solid-state electronics complement the mechanical float for dependable operation.
Frequently Asked Questions
How does the Johnson Pump Electro Magnetic Float Switch prevent false starts?
The switch utilizes a combination of its mechanical float action and solid-state electronics. This design ensures that the pump is only activated when a sufficient water level is present, preventing activation from minor waves or boat movement that could trigger less sophisticated switches.
What is the activation and deactivation water level for this float switch?
This float switch is engineered to activate your bilge pump when the water level reaches approximately 2 inches. It will then deactivate the pump once the water level recedes to approximately 3/4 of an inch.
What is the maximum amperage this float switch can handle?
The Johnson Pump Electro Magnetic Float Switch is designed to handle a maximum electrical load of 15 amps. It is crucial to match this rating with your bilge pump's amperage draw to ensure proper function and safety.
Is this float switch suitable for 12V systems?
Yes, this float switch is specifically designed and optimized for use with standard 12V DC marine electrical systems, commonly found on a wide range of recreational boats.
What materials is the Johnson Pump Electro Magnetic Float Switch made from?
The housing of the Johnson Pump Electro Magnetic Float Switch is constructed from a high-impact plastic designed to withstand the rigors of the marine environment, and its internal electronics are encapsulated for added protection and durability.
