1478620-5 Snap Action, Limit Switches: Application Field and Working Principle

Snap action, limit switches are type of contacts used in electrical circuit switch that open or close the circuit when a force is applied. These switches have a wide range of applications, the most common being found in home appliances, automotive applications, industrial control systems and marine systems. 1478620-5 is a type of snap action limit switch which offers a rugged construction and reliable switching performance.

Application Field

1478620-5 snap action, limit switches can be used in a number of industrial and automotive applications. Automotive applications include switches for reversing lights, parking lights, air conditioning/climate control and front panel controls. In the industrial sector, these switches can be found in applications such as production line machinery, robotics, factory automation systems and materials handling equipment.

Working Principle

The working principle of 1478620-5 snap action, limit switch lies in the principles of Newton\'s third law of motion. This states that "for every action there is an equal and opposite reaction." In simpler terms, when a force is applied, it will move an object in the opposite direction to the force applied. This is exactly what happens when the switch is activated. When the switch is in electrical contact, a small mechanical actuator is hit with a force which then pushes the contacts of the switch open or closed, depending on the direction of force. This is known as "snap action". As the contacts open or close, it will allow electricity to flow through the circuit in either direction depending on the state of the switch.The 1478620-5 can be used in both normally open and normally closed configurations, giving them greater flexibility when used in applications. The switch also features adjustable positive and negative operating forces, making them suitable for applications which require a manual trigger to activate the switch.

Features

The 1478620-5 snap action, limit switch has a number of features which make it suitable for a wide range of applications. The main features of the switch are outlined below: • Robust construction including stainless steel housing and actuators• Variety of actuation and contact configurations including normally open and normally closed• Adjustable operating forces• Adjustable contact gap• High dielectric strength of 1500V AC• Operating temperature range of -20°C to +85°C

Conclusion

The 1478620-5 snap action, limit switch is a reliable, high-performance switch suitable for a variety of applications. The switch is ruggedly constructed and features adjustable operating forces, adjustable contact gap and high dielectric strength. The switch is suitable for applications in the automotive, industrial and marine industries.
