Munro Safe Liquid Level Control

The old adage, “Better to be safe than sorry,” couldn’t be more true when it comes to mixing water and electricity. That’s why Munro’s Extended Controls Family includes safe external output options. Traditional float switches wired for 110V or 220V line voltage can create an immediate, potentially life-threatening hazard if they fail. Munro’s approach shifts control to safe 24V circuits – protecting people, pets, and property.

For added convenience, Munro offers controls paired with pump-up or pump-down float options – giving you reliable, low-voltage control whether you need to fill a tank, empty a tank, or maintain water levels.

Why Use a Transformer to Convert Line Voltage to 24V in Float Switch Applications?

Improved Electrical Safety – Especially Around Water

24v AC or DC control circuits are considered safe low voltage. If wiring is damaged or is exposed to water, there’s considerably less risk of shock or injury.

Code Compliance and Best Practice

Many electrical codes or safety standards discourage or prohibit high voltage switching in water or damp locations unless extra safety measures are used. Using a transformer and 24V control is often the recommended or required best practice, particularly in commercial, industrial, or agricultural pump applications.

Easier Integration with Other Controls

Using 24V signals from your float switch makes it easy to:

• Interface with relays, contactors, or smart controllers

• Add logic or timers
