Wide Angle Float Sw, 10' Cord, N.O.

The American Granby Wide Angle Float Switch with a 10-foot cord (Normally Open) is an automatic liquid-level control used to switch pumps, motors, and other electrical devices on or off as the water level changes. The float's position tilts a sealed switch element inside the housing, making or breaking the circuit at preset levels and giving you reliable, unattended level control.

Understanding N.O. vs N.C.

As the manufacturer explains, the switch is used to control pumps, motors, or other electrical devices, and the Normally Open (N.O.) or Normally Closed (N.C.) designation refers to the state of the switch contacts when the bulb is hanging in a vertical position. Use N.O. to turn a device on when the level rises to a high point, and use N.C. to turn a device off when the level rises. This Normally Open version is the right choice when you want rising water to start equipment, such as activating a drainage or sump pump as a basin fills, or kicking on a transfer pump when a holding tank reaches a set level.

• American Granby wide angle float switch
• 10-foot cord for flexible placement
• Normally Open (N.O.) contact configuration
• Turns a device on as the water level rises
• Suited to sump, drainage, and tank-fill control
• Wide-angle action for a stable on/off differential

The wide-angle design is a meaningful benefit: it provides a comfortable differential between the switching points so the pump or motor isn't constantly cycling on and off as the water surface ripples or the level hovers near a setpoint. That reduced cycling helps protect the connected equipment and extends its service life. Float switches of this type are widely used across sump, effluent, dewatering, tank, and water-treatment applications wherever automatic level-based control is needed. Before installing, confirm that the switch's electrical ratings are appropriate for your load, mount the float so it can swing completely freely at the level where you want the device to activate, keep it clear of tank walls and fittings that could obstruct its travel, and secure the cord to prevent chafing or tangling over time. As a simple, proven device for level-based automation, this normally open float switch is an economical way to add reliable, hands-free control to a wide range of water-handling tasks.
