Common Concerns Answered
Is the 15A limit sufficient for my high-draw bilge pump?
The 15A limit is suitable for many standard bilge pumps. However, for pumps exceeding this amperage, consider a higher-rated switch. Always verify your pump's maximum current draw against the switch specifications to ensure compatibility and prevent component failure.
Are there any known issues with long-term reliability?
While generally reliable, occasional reports of switch failure over extended, heavy-use periods exist. This is not a widespread issue, and the switch's robust construction and sealed design contribute to its overall durability in marine applications. Proper installation and maintenance are key.
How does the Johnson Pump Electro Magnetic Float Switch compare to other brands regarding features?
This switch distinguishes itself with integrated false start prevention and encapsulated electronics, features not always specified by competitors like the Rule-A-Matic Plus. Its sealed mechanical design offers a robust alternative to purely electronic sensors.
Frequently Asked Questions
How does the Johnson Pump Electro Magnetic Float Switch prevent false starts?
It utilizes a combination of solid-state electronics and a sealed mechanical float. This design ensures that the pump only activates when a specific water level is consistently detected, preventing activation from minor wave action or sloshing that could trigger simpler float designs.
What is the activation and deactivation water level for this float switch?
The switch is engineered to activate your bilge pump when the water level reaches approximately 2 inches. It will deactivate the pump once the water level drops to approximately 3/4 inch.
What is the maximum amperage this float switch can handle?
This float switch is rated to handle a maximum of 15 amps. Ensure your connected bilge pump's continuous or surge amperage draw does not exceed this rating to prevent damage to the switch.
Is this float switch suitable for 12V systems?
Yes, the Johnson Pump Electro Magnetic Float Switch is specifically designed for and compatible with 12V DC marine electrical systems.
What materials is the Johnson Pump Electro Magnetic Float Switch made from?
The primary construction material is high-impact plastic, designed to withstand the harsh marine environment. The internal electronics are encapsulated for added protection against moisture and corrosion.
