Float Switches

Designed for accurate liquid level control in many applications including sewage and wastewater environments. The float switch can be utilized to signify specific water levels or for direct alarm actuation.

NORMALLY OPEN (N/O)

As the float rises 1″ (5 degrees) above horizontal, the contacts become closed and actuate (turn on) the switch. The float is generally used in pump down applications.

NORMALLY CLOSED (N/C)

As the float rises 1″ (5 degrees) above horizontal, the contacts become open and actuate (turn off) the switch. This float is generally used in pump up applications.

SINGLE POLE, DOUBLE THROW (SPDT)

A variation of the N/O & N/C, this float switch can be wired to operate as either (but not both) a normally open or normally closed switch based on the user’s need.

The float uses a steel tube mercury switch designed to operate under min/max temperatures of 32 -170 ? F, and has an electrical rating of 10 AMPS @ 120 VAC, 3 AMPS @ 240 VAC.

The power cord is a chlorinated polyethylene type SJOOW-300 Volt on 18/2 for N/O or N/C switch or 18/3 for SPDT switch.

The float is constructed of a durable polypropylene outer shell and a solid polyurethane foam interior. It is tested and proven to be leak proof, shock proof, and impact resistant. For use with intrinsically safe circuits.

The cord weight is made of zinc plated cast iron. At 1.22 lbs., the split weight design allows for easy adjustment, and a secure and permanent attachment to the cord.
