Snap Action, Limit Switches—83278601 Application Field and Working Principle

The 83278601 Snap Action Limit Switches are a highly versatile, economical, and reliable control switch that is suitable for many switch functions. Utilizing robust nylon housing plus either a plunger or roller lever actuator, snap action limit switches are suitable for a wide variety of applications ranging from machine safeguarding to data collection.

Applications

Snap action limit switches have a broad range of applications and are often used for high-stress operations such as machine safeguarding or data collection. Examples of common applications include (but are not limited to):

• Machine Safeguarding: Snap action limit switches are often used in machine safeguarding applications to detect the presence of a guard before operation is permitted. This will ensure that personnel do not operate the machine without the guard in place and protect against hazards.
• Automated Equipment: Snap action limit switches can be used in automated equipment to detect the presence of objects in a specific area. For example, they can be used to detect the presence of parts on an assembly line and trigger the next action in the sequence.
• Data Collection: Snap action limit switches can also be used to collect data. For example, they can be used to detect whether a machine is running and provide data that can be used for troubleshooting and diagnostics.
• Industrial Monitoring and Control: Snap action limit switches can be used to monitor and adjust conditions in industrial settings. They can be used to monitor temperature and pressure levels and are often used in conjunction with control systems.

Working Principle

The working principle of a snap action limit switch is relatively simple. When the plunger or roller lever actuator is depressed, it will make contact with the internal contacts, completing the circuit and activating the switch. When the actuator is released, the contacts will separate and the circuit will be broken, deactivating the switch.The snap action limit switch is designed so that when the actuator is depressed, it will snap back quickly, thus providing a positive action. This ensures that the circuit is broken or completed reliably and quickly without requiring any user interaction.

Advantages

There are numerous advantages to using snap action limit switches. Here are some of the major benefits:

• Durability: Snap action limit switches are designed to withstand harsh environments and have a long service life due to their robust nylon housing and mechanisms.
• Reliability: Snap action limit switches are designed to provide reliable performance, even in high-stress applications. This is due to their quick-acting nature and positive action.
• Cost-Effective: Snap action limit switches are an economical solution compared to other types of switches and are suitable for a wide range of applications.
• Versatility: Snap action limit switches are highly versatile and can be used for applications ranging from machine safeguarding to data collection.

Conclusion

The 83278601 Snap Action Limit Switches are highly versatile, economical, and reliable control switches that are suitable for a wide range of applications. With their robust nylon housing, quick-acting mechanism, and positive action, they provide reliable performance even in high-stress applications. With a long service life and cost-effectiveness, these switches are a great option for many applications.
