AXEON Big Switch Series Float Switch, 220V

Automate Pump Control in Water Filtration and Reservoir Systems With a 220V Float Switch

Float switches automate pump operation based on water level — triggering a pump to start when the reservoir drops below a set level (fill mode) or triggering a pump to stop when the reservoir reaches a set level (drain mode). In grow facilities, float switches are used in water storage tanks, RO product water reservoirs, nutrient mixing tanks, and flood tables.

The AXEON Big Switch Series float switch is rated at 15 amps — high enough to directly control both small and large horsepower pump motors without requiring a separate relay or contactor. The 220V rating suits facilities wired for 220V pump circuits. The mercury-free mechanical switching mechanism eliminates the environmental and disposal concerns associated with older mercury-type float switches.

Key Features & Benefits

• 15-amp switching capacity — rated to directly switch small and large horsepower pumps without a relay — the 15-amp capacity covers most grow facility pump motors.
• 220V rated — designed for 220V pump circuits — confirm your pump circuit voltage before purchasing.
• Mercury-free mechanical switching — patented mechanism eliminates the use of hazardous mercury, making the switch safe to dispose of at end of life without hazardous waste handling.
• Fine-stranded copper wiring — fine-stranded conductors provide flexibility and fatigue resistance in applications where the float is continuously moving with water level.
• Environmentally safe — mercury-free design meets environmental standards for pump control switching components.
• Suitable for small and large pump horsepower — 15-amp capacity supports a wide range of pump motor sizes used in grow facility water supply and irrigation systems.

Who Should Use the AXEON Big Switch Series Float Switch

Grow facility operators and water treatment system builders who need a 15-amp, 220V float switch for automatic pump level control in water storage tanks, RO product water reservoirs, nutrient mixing tanks, or irrigation supply reservoirs.

Float Switch Wiring and Installation Notes

Confirm the pump circuit voltage (220V) and amperage (≤15A) before installation. Connect the float switch in series with the pump circuit according to your control wiring diagram — normally-open for fill mode, normally-closed for drain/overflow mode. Mount the float at the desired trigger level in the reservoir, ensuring the float can move freely without restriction from walls or other equipment.

Frequently Asked Questions

What is the maximum pump motor amperage this switch can handle?

The Big Switch Series float switch is rated at 15 amps, which covers most grow facility pump applications. For pump motors drawing more than 15 amps, use the float switch to trigger a relay or contactor rather than switching the motor directly.

Is this switch available in 110V?

The AXR1700 is the 220V model. Check with your distributor for AXEON 110V float switch options if your pump circuit runs at 110V.

Why is mercury-free switching important?

Mercury is a hazardous material — older mercury tilt switches require special handling at end of life and can be an environmental liability. Mercury-free mechanical switches have no such disposal restriction.

Can I use this switch in a nutrient reservoir or does it need to be in clean water only?

The switch body should be rated for immersion in the solution it will contact. Consult the product specification for chemical compatibility with the nutrient or treatment solution present.
