Snap Action, Limit Switches provide the ultimate solution for all of your On/Off needs. From process control, instrumentation, robotics, machine vision and other automated applications, the Snap Action, Limit Switch is designed to be reliable and highly accurate.

Introduction

A snap action, limit switch is an electric switch in which the contacts remain closed until force is applied to open them; conversely, when more force is applied, the contacts will open. Snap action limit switches are often used on safety circuits to ensure that machinery is stopped during emergency situations. It is also used on process controls to sense the position of motors, track motion, and control the speed of power tools.

Application Fields

Snap action, limit switches can be used in a variety of different applications in order to monitor and regulate various processes. Some of the most common applications for snap action limit switches include:

• Industrial Controls
• HVAC Equipment
• Robotics
• Industrial Machinery
• Automated Assembly
• Sensor Technology

Working Principle

The working principle of a snap action, limit switch is relatively simple and straightforward. When the plunger is in its “relaxed” position, the contacts will remain closed. When the plunger is moved, the contacts will open, thus breaking the circuit. The movement of the plunger is usually limited to only a few millimeters - however, the tolerance of the unit can be adjusted to meet your specific control requirements.

The force of the plunger is achieved through a spring mechanism. The spring pushes the plunger into an open position when the switch is engaged. The spring is adjustable and can be used to set the switch’s operating travel and the desired force. This ensures that the switch is operating correctly and efficiently.

Advantages and Disadvantages

Snap action, limit switches are highly reliable and accurate, making them ideal for a variety of applications. These switches are also relatively low cost, which makes them attractive for cost-conscious applications. Additionally, these switches can be easily modified to meet specific requirements, such as the desired travel or the desired force.

The main disadvantage of snap action, limit switches is that they are not as robust as some other types of switches. Additionally, they are limited in their temperature range and are not suitable for certain hazardous applications.

Conclusion

As you can see, snap action, limit switches are versatile and accurate switches that can be used for a variety of applications. They are relatively low cost and can be easily modified to meet your specific control requirements. However, they are not as robust as some other types of switches and are limited in their temperature range.

By understanding the applications, working principle and advantages and disadvantages of these switches, you can make an informed decision on whether or not they are the best switches for your needs.
