Components
A level rocker – also known as a float switch – is a mechanical sensor that “rocks” depending on the liquid level. When the level rises, the rocker floats up and activates a contact point inside the rocker. It can be used to turn a pump on or off, sound an alarm or activate other controls.
Level switches are widely used in wastewater, rainwater, drainage and industrial fluids. They can be installed quickly and work without electronics or programming.
A level rocker typically consists of:
A plastic or rubber float containing a switch
A cable that connects to the pump or controller
A counterweight or attachment that determines the tilt point
When the liquid rises to a certain level, the rocker changes position and shuts off (or opens) the flow. You can use one rocker for on/off – or two rockers where one controls start and another controls stop.
