The JK105 float-actuated level switch controls water supply or drainage in pools, water tanks and water towers. A suspended float operates the mechanical lever as the liquid level changes, producing the contact action used by the pump-control circuit. Typical applications include industrial premises, hotels, apartment buildings and other water storage systems.
The lever diagram shows the open and closed contact positions. Select the operating direction for filling or emptying and position the float mechanism so it can move freely through its operating travel.
The single-phase illustration shows the live and neutral conductors and the two water-level positions. Its circuit voltage is marked 200V. This is a circuit example; it does not establish a universal motor-current or contact rating for every switch configuration.
The 380V three-phase illustration uses a contactor in the pump circuit and shows the high- and low-level states. Select the external contactor and motor protection for the pump duty, and match the level-switch contacts to the control circuit.
