NEW! Mac3 Float Switch – Key Green – made with Recycled Plastic

Is it possible to take a superb idea, and make it better? If pop culture has taught as anything, it is rare (with a few notable exceptions) for a sequel to surpass the original. However, bucking the normal trend, Mac3 have managed just this!

By taking the proven and trusted design of the Key Float Switch, and using 100% recycled plastic for the float body – well, does it get any better? We have the tried and tested design, along with the globally renowned quality, attention to detail and product innovation, and a solid commitment to the environment and waste reduction!

The Key, in recycled plastic, is the perfect choice for those who want to combine reliability with environmental responsibility. Contact us to include it in your next project.

While there isn’t much more to say about the Key Green, (as the Key float switch design has been adopted by so many OEM users). However,  it is most definitely a positive step into the circular economy for what has become a universal clean-water float switch.

If you closed your eyes and pictured a float switch – I’d wager you imagine the Key from Mac3.

The Key is a solid and straightforward float switch, with the expected attention to detail you would expect from Mac3. Simply put, they work! There isn’t much I can say about these other than these blue and yellow float switches are a familiar fixture on OEM float-switched pumps worldwide.

The Key is available in PVC and H07RN-F cable types, in 2, 5, 10, 15 and 20m lengths. The Key is installed with a counterweight on the cable or with the cable restrained to a pump or internal fixture of a tank installation.

Where the Key Clean Water Float Switch can be Installed

The Key is suitable for use with a tank level controller, pump float switch modification or a complete tank and pump control system.

The Key is particularly suitable as a hardware dry-run protection measure. The Key, wired directly into the mains feed to a pump (with an IP68-rated connector) or using a junction box outside the tank, will isolate the pump when the water level drops below the level set at installation. Using the Key for dry-run protection is particularly useful with centrifugal pumps (as they will require re-priming if they run dry) or when using a submerged pump that requires immersion for cooling.

Conversely, the Key can be employed as part of a top-up system for filling the tank or simply as tethered float switch – positioned at the maximum required level of the tank itself. It can then either be wired into a controller for a manual pump or wired into an automatic pump.

The Key is a nigh-on universal float switch for clean water applications and certainly worth keeping in mind when replacing a failed float switch in situ.
