There are several types of float switches available on the market, but the most common is the normally closed (NC) float switch. As its name implies, the NC float switch has a circuit that is closed when the float is in its up position (above the liquid level). When the float drops down (below the liquid level), the circuit opens. NC float switches are often used in applications where it is important to prevent liquid from overflowing from a tank.
Why Normally Closed Float Switch Is Necessary?
A float switch is a device used to detect the level of liquid in a tank. The switch is typically used in a pump control system to automatically activate and deactivate the pump as needed. A float switch consists of a float, which is buoyant, and a cable attached to the float. The cable runs from the float to a magnetic or solid-state relay, which controls the pump.
A typical application for afloat switchis in adrainage systemwherethepump must be activated when the water levelreachesa certain point,and then shut off again whenthewater has been drained below that same point.

Float Switch, Normally Closed, 120/230VAC
A float switch is a device used to detect the level of liquid in a tank. The switch consists of a float, which is attached to a long rod or cable, and a switch mechanism, which is mounted on the side of the tank. When the liquid level in the tank rises or falls, the float moves up or down, which activates or deactivates the switch.
Float switches are used in a variety of applications, including sump pumps, sewage pumps, and bilge pumps. They are also used in industrial process control, to monitor the level of liquids in tanks and vessels. In some cases, multiple float switches may be used in a single application, to provide redundancy and improve reliability.
Float switches are available in a variety of styles and configurations. The most common type is the float switch, which has a switch mechanism that is activated by the rising or falling of the float. Other types of float switches include magnetic float switches, which use a magnet to activate the switch, and vibrating float switches, which use a vibrating rod to activate the switch.
There are two main types of float switches: normally open (NO) and normally closed (NC). A normally open float switch is closed when the float is raised, and

BRODY Automatic Float Switch Water Tank Level Sensor on/off control with 10′ Cable Sump Pump
One of the most common pieces of hardware that people use in order to control the level of water in their tanks is the BRODY automatic float switch. This particular float switch is designed to be used with a sump pump in order to automatically turn the pump on and off as the water level in the tank changes. The float switch itself is a simple device that consists of a float that is attached to a long cable. The other end of the cable is connected to a control box that is mounted on the side of the tank.
The way that the float switch works is that as the water level in the tank rises, the float will rise with it. Once the float reaches a certain point, it will activate the switch which will then turn on the pump. As the water level in the tank begins to drop, the float will also drop and will eventually turn the pump off. The float switch is an effective way to automatically control the water level in a tank without the need for constant supervision.

Float Switch, Normally Closed, 120VAC, Plug
A float switch is a device used to sense the level of liquid in a tank. The switch may be used in a pump control circuit to automatically turn a pump on or off. A float switch consists of a float, which is connected to a switch. The float rests on the surface of the liquid. As the level of the liquid rises or falls, the float moves up or down, which opens or closes the switch.
There are two types of float switches: normally open (NO) and normally closed (NC). A normally open float switch will turn the pump on when the liquid level rises. A normally closed float switch will turn the pump off when the liquid level rises.
Float switches are used in a variety of applications, including sump pumps, sewage lift stations, and irrigation systems.

Benefits of Normally Closed Float Switch
A float switch is a simple device that can be used to detect the level of liquid in a tank. The most common type of float switch is the normally closed (NC) float switch. When the liquid level reaches the predetermined high point, the NC contact opens and an alarm or other signal is generated.
The main benefit of using an NC float switch is that it can help prevent overflow conditions before they occur. By continuously monitoring the liquid level in a tank, an NC float switch can provide early warning of rising levels and give operators time to take corrective action.
Another benefit of NCfloat switches is their flexibility. They can be easily installed in existing tanks or piping systems and don’t require any special mounting hardware. In addition, they are available in a variety of sizes and materials to suit different applications.
Buying Guide for Best Normally Closed Float Switch
A float switch is a device used to detect the level of liquid in a tank. The switch may be used to control a pump, sound an alarm, or activate a visual indicator. Float switches are available in a variety of designs. This guide will help you select the best float switch for your application.
There are two basic types of float switches: normally open (NO) and normally closed (NC). A NO float switch will close when the liquid level rises and open when the liquid level falls. An NC float switch will open when the liquid level rises and close when the liquid level falls. Most float switches are designed to operate at a specific water temperature.
When selecting a float switch, you must first determine the maximum and minimum water levels that need to be detected. The next step is to select a switch with a range that includes these levels. Once you have determined the range, you can narrow your selection by considering other factors such as contact configuration, wiring method, material compatibility, and approval listings.
The following table can be used as a general guide for selection of NO and NC type float switches:
Type of Switch | Maximum Water Level | Minimum Water Level
—|—|—
NO | 2 inches below top of tank | 1 inch above bottom of tank
NC | 1 inch below top of tank | 2 inches above bottom of tank
