Pump Float Switches
Pump float switches or sump pump float switches are small float switch which hangs in a septic tank. As the level of water rises the vertical float switch gradually rises with the present water. When the water level along with the float switch reaches a particular height, at the height the switch is activated and the pump is turned off. There are mainly two types of pump float switches, one is “Mercury Activated” and another is “Mechanical”.” Mercury activated” switches are very reliable and have a long lasting capacities compared to the “Mechanical” float switches. The price of “Mechanical” switches is much less than “Mercury Activated” switches. The sump pump float switches can be further divided into few sub types. In this article I will discuss about those sub types of pump float switch. Vertical float Switch This kind of switches is cheap and also comes in great quality. The switch floats on the water and when the water level reaches a certain level then the switch is triggered. The advantage of this switch is that it does not get jammed or stuck because here the movement of the switch is limited and it only flows up or down.
Diaphragm Switch These types of switches are very expensive and are mostly used by professionals. It is immersed in the water and is very sensitive to the pressure created by the water. As the pressure increases the switch becomes concave and it turns on the switch. As the pressure becomes less the switch is turned off. Electronic Switch This kind of switches are called flood free switch. This type of switches is immerged in the water and working is dependent on the water pressure. The water pressure activates the probe wire that is present in the septic tank and triggers the switch.
