## Abstract

A float assembly comprising a float traveling along a rod until making contact with either an upper or a lower adjustable stopper, so that an actuator lever having one or more counterweights in mechanical coupling with a switch, so that the float assembly may respond to the fluid level.

## Claims

### Claim 1

A float operated electric switch actuating mechanism comprising;
an electric switch;
a float;
a frame limiting the displacement of a rod to a vertical dimension, wherein said float slides along the length of said rod in response to the fluid level, said rod having a cross beam mechanically connected to said electric switch so that said cross beam movement activates/deactivates said switch as said rod moves;
wherein said cross beam's pivot point is mechanically linked to said frame at a near end, said cross beam makes contact with said switch at a point between said near end and said mechanical connection to said rod and said cross beam further extends to form said beam's distal end;
an adjustable upper limit nut located along the upper portion of said rod; and
an adjustable lower limit nut located along the lower portion of said rod.

### Claim 2

A method for operating a float operated electric switch actuating mechanism, said method comprising;
providing a float mechanism comprised of an electric switch, a float, a frame limiting the displacement of a rod to a vertical dimension, wherein said float slides along the length of said rod in response to the fluid level, said rod having a cross beam mechanically connected to said electric switch so that said cross beam movement activates/deactivates said switch as said rod moves, wherein said cross beam's pivot point is mechanically linked to said frame at a near end, said cross beam makes contact with said switch at a point between said near end and said mechanical connection to said rod and said cross beam further extends to form said beam's distal end, an adjustable upper limit nut located along the upper portion of said rod and an adjustable lower limit nut located along the lower portion of said rod; and
using the inputs from the above float to selectively refill a fluid volume.
