Snap Action, Limit Switches: GLAA01K8B Application Field and Working Principle

Snap action switches, also known as limit switches, are designed to promptly react to a preset pressure force or travel. These switches are most commonly used as proximity switches, wherein they detect the presence or absence of an object without actually touching it. This type of switches usually employs a movable armature, lever, or plunger that is actuated by pressure-sensitive components. The actuation force applied can vary from mechanical, electrical or thermal forces.

The GLAA01K8B switch is an example of a snap action switch. It is a General Purpose Limit Switch specifically designed for reliable long lasting performance, and is suitable for a variety of different applications, including industrial, automotive, and packaged equipment use. It is capable of performing reliable and precise switching at mechanical travel speeds of 20 cpm.

Working Principle:

The GLAA01K8B Limit Switch consists of an outer shell or housing that houses the actuator, contact point assembly, and a rubber boot or cover for protection. The actuator works off of pressure applied from the contact point assembly. The actuator is a lever that pivots when pressure is applied. The contact point assembly is a intricate system of plate springs, contact blocks, and switching mechanisms that move together when pressure is applied to the actuating lever. The rubber boot or cover is designed to protect the limit switch from external contamination.

When the actuating lever is pressed, the contact point assembly is forced together, with the contact blocks touching each other to complete the circuit. This ultimately causes the switch to close. When the force is removed from the actuating lever, the contact blocks separate and the circuit is broken. This closes the switch and allows current to flow through. The actuating lever is designed to break away from the contact point assembly when a certain amount of force is reached, thus protecting the switch and preventing damage.

Applications:

The GLAA01K8B Limit Switch is suitable for a wide variety of applications, such as controlling motors, robotics, and other automation applications. This switch is also suitable for line power and motor protection, safety protection, and vending machine operation. The GLAA01K8B switch is reliable, lightweight, and can be easily installed into existing systems. Additionally, it is capable of withstanding a wide range of temperatures and humidities.

Its unique design and construction also make it suitable for use in both wet and dry conditions, as well as harsh environments. This makes it an ideal choice for applications in the food and beverage, mining and construction, automotive, and packaging industries. Additionally, it is also suitable for aviation, medical, and instrumentation applications. The GLAA01K8B Limit Switch is also highly reliable, making it an excellent choice in critical applications.

Conclusion:

The GLAA01K8B Limit Switch is a snap action, limit switch that is reliable, lightweight, and suitable for a variety of applications. It is designed to break away from the contact point assembly when a certain amount of force is reached, thus protecting the switch and preventing damage. The GLAA01K8B switch is also highly reliable, making it an excellent choice in critical applications, and is suitable for use in both wet and dry conditions, as well as harsh environments.
