KA Series Multi-Level Float Switch
Up to Four Switch Points in One Float
The KA float switches’ revolutionary design incorporates up to four
switch points in a single float. This means that a lift station with
four float switches can replace them all with just one KA float.
Stop dealing with tangled cables, and frequent replacements. The
KA float switches do more with less, and last longer than any other
float on the market.
Give us a call at (888) 525-7300 to learn more.
One Float Switch - Four Switch Points
Up to four switches in one float
No more tangled cables
Easier installation and maintenance
APG
R
Intrinsically Safe
KA float switches are simple devices
Just add an intrinsically safe barrier
Longest Lasting
High chemical compatibility
Extremely durable build
Built-in Hysteresis
Mechanical hysteresis avoids “chatter”
Simplify panel design
Can work independent of any control system
Perfect for back-up pump control
Multiple Configurations
We have a model that fits your panel design
1-4 switch points to meet your application needs
Normally open, normally closed, and hysteresis options
No Lead, No Mercury
Both the switch and the weight are lead and mercury free
