Description
Product Overview
The SJE Rhombus Float Switch is engineered to deliver precise, automatic water level detection in a compact, rugged package. Constructed from high‑quality grey PVC, the switch housing resists corrosion and chemical exposure, making it suitable for a wide range of fluid handling applications. The device features a wide‑angle float that pivots freely, allowing it to sense liquid levels across a broader vertical range than conventional designs. With a SPDT (single pole double throw) contact configuration, the switch can be wired for normally open (NO) or normally closed (NC) operation, giving installers flexibility to match existing control logic. Rated for 13 A at 230 V and protected to an IP54 rating, the unit can withstand splashing water, dust, and temperatures from –40 °C up to 60 °C (‑40 °F to 140 °F). The built‑in wire‑lead connectors simplify wiring, while the 15‑foot float cord provides ample reach for deep‑well installations. Overall dimensions of 7.7 × 7.5 × 7 inches and a weight of 3 lb keep the unit lightweight yet sturdy, and the brass contact material ensures long‑term electrical reliability.

Usage
This float switch excels in applications where continuous water level monitoring is critical. It is commonly used with water pumps, pump control panels, and irrigation systems to automatically start or stop a pump when the liquid reaches a preset level. The wide‑angle float design makes it ideal for tanks, wells, sumps, and reservoirs where the water surface may fluctuate rapidly. Because the switch is rated for potable water, it can be safely employed in domestic water storage, rainwater harvesting, and municipal water treatment facilities. The IP54 rating also permits installation in outdoor environments exposed to rain, dust, and moderate temperature swings, such as agricultural ponds, construction site dewatering pits, and cooling tower basins. The 15‑ft cord length allows the float to be positioned deep within a tank while the switch body remains accessible for maintenance. Electrical professionals appreciate the SPDT configuration for integrating the switch into existing PLC or relay logic without additional conversion hardware.
Why Choose Us
Choosing the SJE Rhombus Float Switch means selecting a product backed by decades of industrial expertise and rigorous quality control. Each unit is manufactured in the United States under ISO‑9001 standards, ensuring consistent performance and traceability. The PVC housing is UV‑stabilized, preventing brittleness and cracking even after prolonged sun exposure. Brass contacts are silver‑plated to reduce oxidation and maintain low resistance over the product’s lifespan. Our engineering team has optimized the float geometry to deliver a 30 % wider detection angle compared with standard switches, reducing the likelihood of missed level changes. In addition, we provide comprehensive technical support, including wiring diagrams, installation guides, and a dedicated helpline for troubleshooting. Should any issue arise, our warranty covers replacement or repair for up to two years, reflecting our confidence in the switch’s durability and reliability.

FAQ
What types of fluids can the float switch be used with?
The switch is designed for potable water and other non‑corrosive liquids. Its PVC construction resists most chemicals, but it is not recommended for highly acidic or alkaline solutions that could degrade the material.
Can the switch be installed in a vertical or horizontal orientation?
Yes. The float is free to move in any direction, allowing the switch to function correctly whether mounted vertically in a tank or horizontally in a sump. The wire‑lead connector should remain upright for optimal connection integrity.
How does the SPDT configuration affect my control circuit?
SPDT provides a common terminal and two selectable outputs (normally open and normally closed). This lets you choose the most appropriate logic for your pump controller or PLC without adding extra relays.
What is the maximum pressure the switch can tolerate?
The unit is rated for a maximum operating pressure of 20 psi, making it suitable for most low‑pressure water handling systems such as domestic tanks, irrigation ponds, and cooling tower basins.
Is there a recommended method for grounding the switch?
While the switch itself does not require a dedicated ground, it is good practice to ground the metal conduit or enclosure that houses the wiring to comply with electrical safety standards and reduce electromagnetic interference.
