Snap Action, Limit Switches

602EN536-1 snap action, limit switches are often used in a variety of application areas. They allow for the reliable and consistent measurement and control of both electrical and mechanical components. In order to understand how these switches work and the advantages they provide, it is important to understand their operating principle and the application field.

Application field

602EN536-1 snap action, limit switches are designed to provide reliable and consistent monitoring, operation and control of electrical and mechanical components. They are often used in a variety of application areas including automotive industry, motor controls, industrial automation systems, general electrical circuits and fire sand safety circuits. Some examples of their application include pressure sensing, level sensing, temperature and position monitoring.

In automotive applications, they are often used in fuel systems, transmission control, engine control and performance monitoring. In industrial automation systems, they are used to provide monitoring, detection, adjustment and feedback. In general electrical circuits, they may be used for preventing an overload on a circuit, controlling a circuit breaker, providing limit and overload protection or providing an interlock system.

Working principle

602EN536-1 snap action, limit switches use a ‘make and break’ contact operating principle. This means that when the contacts open or close, the switch operates. This is enabled by an electrical power source being present in the switch, which monitors for changes in the system. When the switch senses a change in the electrical or mechanical system, it will either close, allowing the current to flow, or open, breaking the circuit.

The contact is usually made of two inner metals, connected by a spring mechanism. When a change in the system is detected, the spring mechanism will flex, allowing the contact to make or break the circuit. This makes the switch suitable for use in both stable, unchanging conditions, and in fluctuating, potentially highly variable settings.

The advantage of using snap action, limit switches is that they are highly reliable and repeatable. When a switch is set to a certain limit, it will stay operating accurately at that limit until it is adjusted. This level of repeatability is critical in ensuring that all components of a module or system remain consistent and reliable.

Conclusion

602EN536-1 snap action, limit switches are highly reliable and repeatable and have a wide range of applications. Their \'make and break\' contact operating principle enables them to provide accurate, consistent and repeatable measurements and control of both electrical and mechanical components. This makes them a reliable choice for monitoring, operation and control of various components.
