Snap Action, Limit switches are mechanical devices that detect the movement or presence of an object in close proximity and convert it into an electrical output. This type of switch, also known as an operator, is widely used in a variety of industrial applications.

The GLAA21C snap action, limit switch is one of the most widely used switches in industries. The GLAA21C is designed to detect the position, velocity or other condition of an object quickly, with a high degree of reliability. The switching contacts are quite durable, and can withstand prolonged switching cycles.

The GLAA21C switch uses a paddle, which is a metal sheet mounted on a rotating mount. When the object to be detected passes near the paddle, the mechanism is triggered and the switch is actuated. Depending upon the orientation of the paddle, the output can either be a normally open (NO) or normally closed (NC) contact.

The switch has a variety of applications in industries. It can be used as a safety switch to monitor the position of a cover or door, or as a proximity sensor for object sensing applications. Other applications include limit switches, which are used to prevent machines from traveling beyond a certain position, and as start/stop switches. The GLAA21C can also be used to count objects, as a stand alone timer, or as an input to a control system.

The GLAA21C snap action switch is easy to install and can be either manually operated by a person, or via an automated control system such as a PLC. It consists of a switch body, a paddle, and the necessary wiring. The switch is wired to an output such as an indicator light or electrical circuit, and the necessary mounting hardware is provided. A 24VAC or DC power supply is generally used to provide power to the switch.

The switch works by using a paddle and a bimetallic strip. The paddle is mounted on a stationary or rotating mount and when an object passes near the paddle, the bimetallic strip senses the change in temperature and causes the switch contacts to open or close. Depending upon the orientation of the paddle, the output can either be a normally open (NO) or normally closed (NC) contact.

The GLAA21C is a reliable switch that is used in a wide range of applications. It is easy to install and connects to any power supply, which makes it well suited for a variety of applications. It is a dependable and cost-effective option for detecting the presence or movement of an object quickly and accurately.
