Product Details

Cynergy3 Horizontal Float Switches

Cynergy3 offers wide range of horizontal switches which are WRAS approved and have low-cost compact design. These horizontal float switches consist of a reed switch and a pivoted actuator magnet and can be used for N/O or N/C operation. The switch action can be reversed by mounting the float switch with the float able to move upwards away from the body instead of downwards.

WRAS approval explained

WRAS is the standard against waste, misuse, undue consumption or contamination of the water supply and must have an appropriate quality and standard.

What materials can you choose from?

• Nylon
• Polypropylene
• Polypropylene Sulfide (PPS)

Features and Benefits

• Operating temperature: -10 °C to +120 °C
• N/O or N/C Switch output
• Switch action may be reversed by rotating the switch through 180º
• Choice of gasket materials: Silicone, Nitrile, Viton or combination of Silicone & Nitrile
• Flying Lead
• M12 plug connection
• Internal & external fitting inside a tank
UL recognised

Typical Applications

These Cynergy3 Horizontal Switches are most likely to be used in vending machines, commercial washing machines and evaporator units.


Suitable for signal switching and for use with transistorised input/low power, suppressed coil miniature relays. Not suited for any inductive or inrush (e.g. filament lamps) loads.

RSF40 Float Switch

The RSF40 Float Switch series is designed for internal fitting. To ensure the quality, high compression seal will take care of getting the job done. This RSF43Y050QF Float Switch is ideal for size sensitive applications.

How is it fitted?

Through the tank wall from the inside, via an M16 thread, therefore it requires access to the inside of the tank.
