they can fail and cause unreliability issues
.
How does a float switch works?
A float switch
detects the level of a liquid in a tank or container. It floats on top of the liquid surface and acts as a mechanical switch as the liquid level goes up or down
. They control devices like pumps (pump water in or out), valves (open or close inlet/outlets), or alarms to notify users.
How does a float switch work on a submersible pump?
A float switch has a floating element that lowers and raises with the water level in the sump basin

Are sump pump switches Universal?
Most Reliable in the Industry
Universal switch is compatible with most sump pumps
; water raises float and switch activates sump pump. The Universal Float Switch is included on all BW, BWT and BWSS Series pumps.
How does a sump pump without a float work?
As the water level rises, the water pressure increases and the diaphragm becomes concave, thereby activating the switch to turn on the sump pump. When the water level drops, the switch turns off. Since there is no float, there is nothing to get stuck, which is a common problem with other types of sump pumps.
How do I manually turn on my sump pump?

are the best of the best.
They’re the gold standard pump switch technology and the most reliable of the options listed above. Electronic float switches will have piggy-back plugs that you plug into the wall outlet. You then plug the pump into the back of the switch plug.
