If you are looking for a reliable way to detect and control water levels in your boat, RV, or other applications, the Rule A Matic float switch is a popular choice. This device feature a unique design that allows it to automatically turn your bilge pump on and off based on the water level in your vessel. In this article, we will discuss how to wire a Rule A Matic float switch for optimal performance and safety.
What is a Rule A Matic Float Switch?
A Rule A Matic float switch is a type of bilge pump switch that uses a float to detect the water level in your vessel. When the water level rises, the float rises with it, triggering the switch to turn on your bilge pump. As the water level falls, the float falls with it, turning the bilge pump off. This process is automatic and requires no manual intervention, making it a convenient and reliable way to keep your boat or RV dry.
How Does a Rule A Matic Float Switch Work?
The Rule A Matic float switch works by using a mercury switch inside the casing. When the switch tilts, the mercury moves to the opposite end, closing the circuit and activating the bilge pump. When the float returns to its original position, the mercury switch returns to its normal position, opening the circuit and deactivating the bilge pump.
One of the advantages of the Rule A Matic float switch is its simple design. This device is compact and easy to install, making it an ideal choice for both DIY enthusiasts and professional technicians. Additionally, the switch is very reliable and durable, with a high-quality construction that can withstand harsh marine environments.
Wiring a Rule A Matic Float Switch
Wiring a Rule A Matic float switch is a relatively straightforward process that requires minimal tools and skills. However, it is important to follow the manufacturer’s instructions carefully to ensure proper installation and operation. Here are the basic steps to wire a Rule A Matic float switch:
Step 1: Mount the Switch
The first step is to mount the switch in a suitable location inside your vessel. The switch should be mounted so that the float moves freely and the switch is level in its normal position. The switch can be mounted using screws or adhesive, depending on the type of mounting bracket provided.
Step 2: Connect the Wires
Next, you will need to connect the wires according to the wiring diagram provided by the manufacturer. Typically, the switch will have three wires: a brown wire for power, a black wire for ground, and a white wire for the bilge pump. The brown wire should be connected to a 12-volt DC power source, the black wire should be connected to ground, and the white wire should be connected to the positive wire of your bilge pump.
Step 3: Test the Switch
After connecting the wires, you should test the switch to make sure it is functioning properly. To do this, fill your bilge with water until the float rises and activates the switch. The bilge pump should turn on automatically and pump out the water. When the water level falls, the float should drop and deactivate the switch, turning off the bilge pump.
FAQ about Rule A Matic Float Switch Wiring Diagram
1. Can I wire a Rule A Matic float switch directly to my battery?
No, you should not wire a Rule A Matic float switch directly to your battery. The switch requires a 12-volt DC power source, but it should be connected to a fused circuit or switch panel instead of directly to the battery. This will protect the switch and prevent damage in case of a short circuit.
2. What size wire should I use to connect the Rule A Matic float switch?
The wire size you should use depends on the length of the wire run and the amperage rating of your bilge pump. Typically, you should use 16-gauge wire for a short run or a low amperage pump, and 14-gauge wire for a longer run or a higher amperage pump. However, it is always best to consult the manufacturer’s instructions or a qualified technician to determine the correct wire size for your specific application.
3. Can I use a Rule A Matic float switch with other types of pumps?
Yes, you can use a Rule A Matic float switch with other types of pumps, including centrifugal, diaphragm, and rotary pumps. However, it is important to make sure the pump is compatible with the switch and that the combined amperage does not exceed the switch rating.
4. How often should I test my Rule A Matic float switch?
You should test your Rule A Matic float switch regularly to make sure it is functioning properly. This will help prevent water damage and ensure the safety of your vessel. It is recommended to test the switch at least once a month or before every use of your boat or RV.
5. Can I install multiple Rule A Matic float switches in my vessel?
Yes, you can install multiple Rule A Matic float switches in your vessel to provide redundancy and backup. This is especially useful for larger boats or RVs with multiple bilge pumps. However, it is important to wire the switches correctly and follow the manufacturer’s instructions to avoid potential issues.
Conclusion
The Rule A Matic float switch is a popular choice for detecting and controlling water levels in boats, RVs, and other applications. By following the wiring diagram and instructions provided by the manufacturer, you can wire this device safely and effectively for optimal performance. Remember to test your switch regularly and consult a qualified technician if you have any questions or concerns.
