Snap action, limit switches are widely used in the industrial control and automation markets. They are found in virtually every application and can feature a range of contact forms, voltages, currents, switches and actuators. The GLAA20B is an excellent example of this technology in action, and as such it is useful to take a closer look at its application field and working principle.

The GLAA20B is a great choice for light duty industrial applications due to its robust construction, ease of installation and reliable performance. It can be mounted without the need for additional hardware, making it quick and easy to use. It can also be used in a wide range of industrial environments, from factories and warehouses to offices and laboratories. The GLAA20B offers a number of contact forms including normally open, normally closed and changeover contact configurations. This makes it suitable for a variety of applications from controlling alarms and signaling devices to controlling pneumatically operated valves and actuators.

The GLAA20B is designed to provide reliable switching action for applications which require accurate and controlled linear operation. It is actuated by a spring-loaded plunger which is moved by an actuating lever. The actuator moves the plunger along a linear path, triggering the switch once a certain limit is reached. Depending on the configuration of the contacts, this can be a normally open, normally closed, or changeover contact. It is also important to note that the GLAA20B is designed for use in AC circuits and should not be used in DC applications.

The primary benefit of using a GLAA20B limit switch is the high contact rating which it offers. With a high contact rating, the switch can handle a higher voltage and current, meaning it can be used in a wide variety of applications. Additionally, the GLAA20B offers a strong durability which makes it ideal for harsh environments. The switch utilises a dust proof construction which means it is not only reliable in operation but also resistant to dust contamination. The switch is also RoHS and UL certified meaning it is suitable for both US and European markets.

Using a limit switch such as the GLAA20B presents a range of advantages over traditional switch solutions. It allows for quick, accurate and reliable operation and is capable of controlling both AC and DC circuits. Additionally, the switch is capable of providing a high contact rating meaning it can be used in a wide variety of applications. The switch is also designed for use in harsh environments making it a great choice for industrial and manufacturing applications. Overall, the GLAA20B is an ideal choice for a wide range of applications where quick and reliable switching action is required.
