Snap action, Limit Switches are commonly used in everyday life for various tasks, from home appliances to industrial use. For industrial use, their primary purpose is to detect the movements of machines and other objects, alerting the operators to their positions and/or working conditions. However, due to their wide range of applications, there is a need for a switch that has a variety of features and is suitable for many different uses. The model 1478669-3 Snap Action, Limit Switch is one model that fulfills these criteria.

Applications

Primarily the 1478669-3 Switch is designed for unidirectional count detection; however, it can also be used for other types of detection. The switch is composed of a stainless steel housing, plunger and spring, and is designed to remain unchanged in size and shape over its lifetime. This makes it very robust and suitable for applications where accuracy and reliability are required. As well as unidirectional count detection, the 1478669-3 can be used to detect edge movement, detect position, detect pressure and detect level. It also offers a variety of functions such as automatic restart, manual reset or interrupt. All these features make this switch a versatile choice for many different applications.

Working Principle

The 1478669-3 Switch is a rotary snap action switch, meaning that when it is actuated, it quickly snaps open or shut. This is achieved by a plunger and spring mechanism, which consists of a rectangular tube with a cylindrical plunger inside. The plunger is pressed against the tube by an external force which then pushes it against a ramp and eventually snaps, either opening or closing the switch depending on the direction applied. This gives the switch its fast and reliable operation, making it suitable for a wide range of uses.One of the advantages of the 1478669-3 Switch is that it is designed to withstand high wear rates and long operating cycles, making it suitable for long-term and industrial use. This is because the design of the plunger prevents interference and wear, ensuring that it remains reliable and accurate over its lifetime. Additionally, the switch is IP55-rated, which means it is dust- and water-resistant, a great feature which further increases its lifespan and usability.Overall, the 1478669-3 Switch is an excellent choice for many different applications. It is highly reliable, with a robust design and a long lifespan. Additionally, it offers a variety of features and functions, making it suitable for a wide range of uses. This combination makes the switch an invaluable addition to any industrial set up, providing accurate and reliable performance for many years.
