Description
Vertical Piggyback Float Switch for Pump Down Applications with Adjustable Control
The Alderon VertiMAC™ piggyback float switch assembly provides reliable liquid level control for sump pump systems, especially in applications where space is limited. This pump-down float switch operates using a vertical float mechanism mounted directly to a pipe, offering stable and consistent performance compared to traditional tethered switches.
Equipped with a 120VAC piggyback plug, this sump pump float switch allows quick installation without complex wiring. The adjustable pumping range and compact vertical design make it ideal for confined sump pits, pump chambers, and wastewater systems.
Key Features of the Alderon VertiMAC™ Piggyback Float Switch
-
Vertical Float Switch Design (Space-Saving):
Mounts directly to a pipe, making it ideal for tight or narrow sump pits where standard float switches cannot operate effectively. -
Adjustable Pumping Range (1.5" – 6"):
Easily adjust the on/off levels by sliding the rubber grommet along the actuator rod to match your system requirements. -
Piggyback Plug for Easy Installation:
Plug-and-play setup—connect the switch to power and plug your pump into the switch for immediate operation. -
Pump Down Operation (Normally Open):
Activates the pump when liquid levels rise and turns it off as levels drop, ensuring proper drainage and preventing overflow. -
Magnetically Activated Waterproof Switch:
Encapsulated switching mechanism provides reliable performance and protection in wet environments. -
Durable SJTOW Cable:
Thermoplastic, flexible, and resistant to water and oil for long-term durability. -
Stable Pipe-Mounted System:
Includes pre-installed pipe clamp bracket and stainless steel clamp for secure mounting and consistent operation.

How the VertiMAC™ Piggyback Float Switch Works
The VertiMAC™ is a float-operated pump control switch designed for automatic liquid level management.
As the water level rises, the float moves upward along the actuator rod, activating the internal switching mechanism and turning the pump on. As the water level drops, the float lowers, deactivating the mechanism and turning the pump off.
This system provides consistent and repeatable control, helping maintain proper liquid levels without manual intervention.
Adjustable Pumping Range for Precise Control
The VertiMAC™ float switch features an adjustable pumping differential ranging from 1.5 inches to 6.0 inches.
By repositioning the rubber grommet on the actuator rod, you can customize when the pump turns on and off. This allows for:
- Improved system efficiency
- Reduced pump cycling
- Better control over liquid levels
Proper adjustment ensures optimal performance and helps prevent issues such as short cycling or dry running.
Ideal Applications
This piggyback float switch is commonly used in:
- Sump pits
- Septic systems
- Pump chambers
- Water tanks
- Wastewater systems
- Confined or narrow basins
Its vertical mounting design makes it especially effective in applications where traditional float switches cannot function properly.

Frequently Asked Questions
What is a piggyback float switch?
A piggyback float switch is a plug-and-play pump control device where the switch plugs into a power outlet, and the pump plugs into the switch, allowing automatic operation without wiring.
What does pump down mean?
A pump-down float switch activates the pump when water levels rise and turns it off when levels drop, helping remove water from a sump or tank.
Can this be used in tight spaces?
Yes, this vertical float switch is specifically designed for confined areas where traditional tethered float switches cannot operate effectively.
How do you adjust the pumping range?
The pumping range is adjusted by moving the rubber grommet along the actuator rod to set the desired on/off levels.
Is this compatible with sump pumps?
Yes, this sump pump float switch is compatible with most sump pumps that support piggyback plug operation and include thermal overload protection.
Does this require professional installation?
Piggyback plug models are easy to install, but installation should follow local electrical codes and guidelines.
Do I need to secure the pipe clamp before setting the float level?
No, the clamp should remain loose until the desired pump-off level is set, then fully tightened to maintain accurate operation.
How do I know if the float switch is working after installation?
After mounting, lift the float up and down manually to test activation and ensure the switch is operating correctly.
