1478601-2 is a type of snap action, limit switch commonly used in the industrial automation. Its application field and working principle will be discussed below.

Application Field

The 1478601-2 snap action, limit switch is used extensively in the automation industry in a wide range of applications. This switch is suited for use in HVAC and motor system control, conveyor and lift applications, robotics and handling equipment, machine tool applications and process control systems. It is also used in pneumatic and hydraulic systems, electric heating and current monitoring systems.

The 1478601-2 snap action, limit switch is typically characterized by its long operating lever type actuator. This type of switch is available with various operating force settings and contact configurations to suit specific application requirements. A variety of mounting arrangements and contact materials are available from the manufacturer.

Working Principle

The 1478601-2 snap action, limit switch has a mechanical cam/plunger type actuating component that is actuated by a lever. When the lever moves from one position to another, the plunger is released and the cam follower contacts the associated contacts. These contacts can be made of metal, metal alloys or plastic, depending on the application.

The plunger can operate in a rotary, push or pull action depending on the application. When it is actuated, the electrical connections, or contacts, are made or broken as the plunger is pressed or released. The contacts, which are typically arranged in an arc, are bowed under the plunger, resulting in an audible ‘snap’ when the switch is actuated.

The 1478601-2 snap action, limit switch has the ability to activate or deactivate a load at one or a number of points in a system’s operation. This results in the switch being able to control the operation of the system over a pre-determined range. The switch can also be used as an indicator to show when a certain operation has been performed or when a certain point has been reached.

Conclusion

The 1478601-2 snap action, limit switch is an essential component in a variety of industrial automation applications. It has a durable, reliable design, with various mounting arrangements and contact materials to suit specific application needs. The versatile actuating component is able to control an electrical load over a range, or act as an indicator to show the completion of an operation or the passing of a certain point.
