FineTek FAB Cable Float Level Switch

FineTek FAB Cable Float Level Switch

The FineTek FA/FB Series cable float level switch is a durable, budget-friendly hanging float switch built from a choice of chemical-resistant materials, with micro switch, reed switch, or mercury switch output options to match your application.

How It Works

As the float rises and tilts upward, the switch transmits an ON or OFF contact signal. Inside the float, a metal ball slides as the angle changes, making or breaking the contact. Different float materials are available to suit water and solution temperatures, with plastic and stainless steel the most common choices.
