SWI S005 Series | Single-Point, Suspended Float Liquid Level Switch


The S005 Single-Point, Suspended Liquid Level Float Switch is a low-cost, float-actuated device intended for vertical mounting within a tank or process vessel. Available in three distinct design options, the S005 can accommodate installations where spacial limitations exist. The switch is also ideal for OEM applications where a single-point high or low level alarm is desired. Additional options include a variety of switch types, cable lengths and PVC cap attachment.

Principles of Operation

The switching action is achieved through the use of a magnetic rod assembly and its interaction with the switch mechanism. As the liquid level fluctuates inside the tank, the float follows and the magnetic rod assembly actuates the switch inside the tube, completing an electrical circuit.
