- [ HEAVY DUTY FLOAT SWITCH ]: SEAFLO SFBS-25-03A is a heavy duty automatic float switch designed to control compatible bilge pumps based on water level. Built for 12V, 24V, and 32V marine systems, this switch helps activate the pump when bilge water rises and shut it off when the water level drops.
- [ NO FILTER HOUSING DESIGN ]: This 03A model is the version without filter housing, making it a compact and lightweight choice for installations where a protective strainer housing is not needed. The simplified body is easy to position in tight bilge spaces and compatible marine pump layouts.
- [ HIGH AMP CAPACITY ]: Designed for demanding bilge pump systems, the SFBS-25-03A supports up to 25A at 12V, 15A at 24V, and 10A at 32V. This heavy duty rating makes it a strong option for boat owners who need reliable automatic water level control for compatible marine pumps.
- [ STABLE FLOAT STRUCTURE ]: The 03 Series uses a larger float and drive structure for improved stability during operation. This helps the switch respond consistently as water rises and falls, improving pump activation reliability in boat bilges, marine compartments, and onboard water management systems.
- [ ULTRASONIC WELDED SEAL ]: SEAFLO 03 Series float switches use ultrasonic welding to form a sealed structure that is reliable, secure, and designed to resist leaking. This construction helps support long-term use in wet bilge environments where water exposure and vibration are common.
- [ AUTOMATIC ON/OFF LEVELS ]: The SFBS-25-03A turns the pump on when water rises above approximately 45-55 mm / 1.77"-1.97" and turns the pump off when water drops below approximately 20-25 mm / 0.79"-0.98". This automatic response helps manage bilge water without constant manual control.
- [ 14 AWG 1M WIRE LEAD ]: Equipped with 14 AWG wiring and a 1 meter wire lead, this float switch is built for practical marine installation. The wire setup supports secure connection to compatible bilge pump systems while giving installers flexibility in tight or compact bilge areas.
- [ COMPACT & EASY INSTALLATION ]: With no filter housing, a compact switch body, and a net weight of only 120g, the SFBS-25-03A is easy to install in tight bilge spaces. Its simple float switch layout and automatic water level operation make it a practical replacement or upgrade for marine pump control systems.
- [ FRESH & SALT WATER USE ]: SEAFLO float switches are designed for use with fresh water and salt water only. The SFBS-25-03A is ideal for boat bilges, marine pumps, automatic pump switching, and onboard water level control where dependable activation is needed.

### ⭐⭐⭐⭐⭐ Bien

### ⭐⭐⭐⭐⭐ Low Profile

It’s a flapper. Low profile. Works good.

### ⭐⭐⭐⭐ So far so good
*by A***R on May 11, 2022*

After a little over a year from installation, this switch still works well. I also purchased a SeaChoice model about the same time that has already failed. This has been the best level switch I've used in several years, including the "Rule" model. I have become frustrated with buying new switches every 6-12 months due to horrible quality. This one seems to be among the better ones but would still rather have a real old-time mercury-wetted, tried and true, type.
