7AC7

Snap Action, Limit Switches:

Snap action, limit switches are electromechanical devices used to detect the presence or absence of an object. They are used in countless applications to detect a wide range of objects, including position, pressure, force, and fluid levels. They are commonly used in industrial automation and control systems, as well as in the healthcare industry. This article will look at the application field and working principle of 7AC7 switches.

7AC7 Application Field:

The 7AC7 switch is an industrial, snap action switch ideal for use in harsh industrial environments. It is a standard, 3-wire, two-position switch and is ideal for controlling motors, heaters, solenoids and other industrial processes. It can be used as a safety switch, a limit switch and as an overload switch. The switch features a robust metal construction, making it suitable for use in a variety of applications, such as in commercial and industrial control applications, in hazardous and demanding environments.

7AC7 Working Principle:

The 7AC7 switch uses a snap action mechanism to detect contact presence. A spring is loaded against a contact lever, and when the contact is opened, the lever snaps against the opposite direction. This creates a distinct and powerful action, allowing for fast and accurate detection. The switch body is constructed of an anti-corrosive, thermoplastic material and is designed to withstand harsh industrial environments. The contact surface is made of a hard, silver contact material, which ensures reliable and consistent contact performance. The switch is designed with a combination of a snap action mechanism, a direct-acting lever, and a sealed-cover design, making it durable and reliable.

Conclusion:

The 7AC7 switch is an ideal choice for a wide range of industrial applications. Its snap action mechanism and robust metal construction make it suitable for a variety of industrial and commercial control applications. The switch is also designed with a sealed-cover design and a direct-acting lever, making it both reliable and durable. The hard, silver contact surface provides reliable and consistent contact performance, making the 7AC7 a perfect choice for those looking for an industrial-grade switch.
