Snap Action, Limit Switches

GLAA01A2Y limit switches are used to detect the movement or presence of an object. There are two types of limit switches— momentary and maintained contact. Momentary contact switches plan to detect the presence or absence of an object, while maintained contact switches detect movement or changes in position of an object. GLAA01A2Y limit switches are ideal for a wide range of applications, including advanced sensors in the aerospace and air conditioning industries, as well as in automotive and machine-building applications.

The working principle of GLAA01A2Y limit switches involves an electrical contact set point, usually a switch or contact point. When the object being monitored moves past the contact point, the contact is opened or closed depending on the type of switch used. This movement triggers an electrical signal either directly connected to the contact point, or through other sensing elements such as optical or acoustic address-, zone-, and position-sensors.

In terms of their snap action design, GLAA01A2Y switches are typically rated to 500VAC, 10A. They are designed for a maximum operating temperature of +120°C with a contact-rated voltage of 250VAC. The construction of the switch includes a spring mounted actuator lever, a roller plunger, a thermoplastic housing and an adjustable bridge lever. When the controlled object passes the roller plunger, the actuator lever will snap the bridge lever and complete the electrical circuit. This action simultaneously opens or closes the switch, depending on the type of switch being used.

When it comes to their applications, GLAA01A2Y switches are most commonly used in industrial automation. The switches are used to detect metal objects passing through a sensing system or to simply detect the presence of metal objects. They are also used as position sensors in robotics, linear lighting systems, or other applications that require the detection of moving parts. GLAA01A2Y limit switches are also used to detect the movement of a sliding door or window, providing security in residential and commercial buildings.

Aside from their use in automation, GLAA01A2Y switches can be found in the vending machine industry. In the vending industry, these types of switches are used to detect the selection of items and handle payments. Additionally, GLAA01A2Y switches can also be used in medical applications, such as in oxygen concentration monitors, ultrasonic imaging sensors, infusion pumps, beds and seats, as well as motion control systems.

GLAA01A2Y limit switches are a valuable, versatile type of switch for a wide range of industrial, commercial, and consumer applications. Their snap action design and adjustable bridge levers provide reliable performance and long-term durability, making them the perfect choice for any application.
