Diaphragm Switches

A diaphragm switch is the most popular type of float switch. These switches are connected to the sump pump that is fully immersed under water. The switch has a very sensitive water pressure gauge and as the water raises the pressure increases and the diaphragm starts being concaved, which triggers the switch to turn on the pump. When the water level and pressure drop the switch turns back off. Keep in mind that if your pump is in a location where there is a lot of movement it may delay or stop the diaphragm switch from being triggered on.
