Madison point level float switches use reed switch technology that is simple, reliable, and durable. They operate in an on/off state, and are used to control an external device such as an alarm or an on/off switch. Because OEMs need sensors for tanks that vary in width and height, certain point level float switches are offered with field-adjustable stem lengths. This provides an OEM with the advantage of using only one or two sensors for their application instead of several.
