Snap Action, Limit Switches - 9EN2C11BC5BB1 Application Field and Working Principle

A snap action switch, often referred to as a limit switch, is an electrical device designed to detect when a preset limit or range of motion has been reached. It is an electromechanical switch, consisting of a steel or brass plunger, enclosed in a plastic housing, which is activated when a predetermined amount of force or physical motion is applied. This type of switch is widely used in the industrial, commercial, and residential sectors and is a popular choice in commercial applications due to its simple and reliable design.

The 9EN2C11BC5BB1 series of snap action switches is a highly reliable, heavy-duty switch. It is a single-pole, double-throw switch with an adjustable actuating force of 0.25 to 2N. It has a PVC insulated housing with screw terminals and operates over a temperature range of -10 to +70°C. The switch is designed for use in a variety of applications including door, window, and machine controls, as well as for alarm and security systems.

The operating principle of a snap action switch is based on the principle of leverage. The switch is equipped with a plunger that is displaced when a certain force is exerted on it. This force is provided by either a spring or a cam. When the switch is deformed, the lever arm of the plunger is pushed, which causes it to pivot, thus changing the position of the switch. This change in position then triggers an electrical circuit, which can be used to switch on or off a variety of electrical devices.

The 9EN2C11BC5BB1 series of snap action switches can be used for many applications, including detection, positioning, machine control, and over-travel protection. These devices are commonly used to switch on or off a variety of electrical devices, such as lights, motors, pumps, buzzers, solenoids, and timers. They can also be used to detect when a preset limit or range of motion has been reached in various machines and systems.

The 9EN2C11BC5BB1 series of snap action switches are highly reliable and require little maintenance. Additionally, they can handle a wide range of temperatures, making them well-suited for use in industrial environments.
