KA Level Float Switch

APG

Flexible by Design

The KA series Cable Suspended Float Switch has options that allow you to replace up to four

single level oat switches with one 4-point level switch. With PVC, Aton rubber and Teon cable
options, the KA offers high chemical compatibility and durable components built to outlast any other.
Kari oat switches utilize high performance miniature switches.

Features

• Mercury and Lead free

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 [phone] 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
