Stainless Steel Magnetic Float Switch Ball [28mmx9mmx28mm]

Description:
A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float. 
Most float switches are “normally closed,” meaning the two wires coming from the top of the switch complete a circuit when the float is at its low point (for example, when a tank is dry).
The small float switch, small liquid level controller and liquid level sensor are mainly composed of a reed switch and a float. 
The float has magnetic material. When the float moves up and down with the measured liquid level, the reed switch is touched to detect the liquid level position.
A very common application is in sump pumps and condensate pumps where the switch detects the rising level of liquid in the sump or tank and energizes an electrical pump which then pumps liquid out until the level of the liquid has been substantially reduced, at which point the pump is switched off again. 
Float switches are often adjustable and can include substantial hysteresis. That is, the switch's "turn on" point may be much higher than the "shut off" point. This minimizes the on-off cycling of the associated pump.
Some float switches contain a two-stage switch. As liquid rises to the trigger point of the first stage, the associated pump is activated. If the liquid continues to rise (perhaps because the pump has failed or its discharge is blocked.), the second stage will be triggered. This stage may switch off the source of the liquid being pumped, trigger an alarm, or both.
