Snap Action, Limit Switches

The 1478602-3 is a snap-action limit switch that is typically used in applications suchas controlling position and level, providing limited over-travel protection, and general control.

Application Field

1478602-3 limit switch is suitable for use in most industrial applications, as well as industrial machines, digital peripheral devices, etc. The slender design and abundant features of the 1478602-3 make it suitable for many applications in which limited space exists.

Working Principle

A limit switch is basically an electrical switching device that operates when its limit is exceeded. It consists of a switch, actuator and adjustable limit switch arm.

The 1478602-3 limit switch has an external adjustable limit arm used to set the limit at which the switch operates. A spring is used to return the switch to its resting position when the limit is not exceeded. When the limit is exceeded, the actuator pushes on the adjustable limit switch arm and the electrical contact is made, completing the circuit.

The actuator can be triggered either by mechanical means, such as a lever arm or a lever, or by an electrical or electronic circuit. When the limit is reached, the switch arm is pushed back, the electrical contact is broken, and the circuit is tripped.

Advantages

1478602-3 limit switches provide several advantages, including:

  • Ease of installation and servicing
  • A reliable, low-cost alternative to mechanically operated switches
  • Compact, low maintenance design
  • Low power consumption
  • Ability to set precise limits

In addition, since they are part of an electrically operated system, they can easily be integrated into existing systems and control systems.

Disadvantages

There are some disadvantages to using 1478602-3 limit switches, including:

  • They can be easily damaged by dust and dirt
  • The switch arms can become stuck or misaligned
  • They are not suitable for high-frequency operation
  • They can be sensitive to environmental conditions, such as temperature and humidity

Conclusion

The 1478602-3 limit switch is a versatile and low-cost switching solution that can be used in various industrial applications. The adjustable switch arm allows for precision operation, while the low power consumption helps to reduce costs. However, the switch is sensitive to environmental conditions and can be easily damaged by dust and dirt. As such, it is important to take the necessary precautions to ensure its proper operation.
