Stem Float Switches

Quick View

Customizable

The FL multi-level float switch comes made to order. From switch configurations to float types and materials, the FL level switch adjusts to meet your specifications.

Works in Tight Spaces

Unlike suspended float switches that require room to operate, this vertical float switch works along a probe, or stem, for linear level measurement in a tight space.

Up To Seven Switch Points

The FL float switch offers up to 7 switch points for increased control and savings. Monitor 7 different levels with a single sensor, and a single mount.

Movable Stem Float Switches

Quick View

Direct Pump Control

The MLS float switch has a 10 A SPDT miniature switch for direct control over small horsepower pumps.

Field Adjustable

The two float stops on the stem of the MLS float switch are field adjustable for optimum switch point control. Simply loosen the screw on the float stop, slide it up or down, and tighten it again.

Mechanical Hysteresis

The MLS float level sensor switches on when the float hits the top float stop, but does not switch off again until the weight of the float itself lands on the bottom stop. This mechanical hysteresis is ideal for pump control.
