Snap Action, Limit Switches

The device type 83261845 is a snap action, limit switch. A limit switch is an electromechanical device used to detect the presence of an object and sense its position by opening or closing an electrical circuit. This type of switch is often used to control a circuit automatically, and it is designed to be opened or closed when a specified level of pressure, movement, or other force is applied to the switch.

General Characteristic

The 83261845 snap action, limit switch is a type of single-pole, double-throw (SPDT) switch, meaning it will open one set of contacts when closed and close the other set when open. The contact arrangement within the switch is designed to open a circuit when the actuator (the moveable piece that contacts the contact points) is pushed forward, and close the circuit when the actuator is pulled back towards the switch body. The 83261845 can operate at 250Vdc/125Vac, 7A current rating.

Features

This limit switch is considered a “snap” switch, as its contact arrangement is designed to open or close a contact as quickly as possible. This design uses a spring, lever and contact mechanism to open or close a circuit with speed, accuracy, and reliability. The switch itself is housed in a rugged plastic body and is capable of withstanding high temperatures and vibrations. The contacts inside the switch are corrosion and resistant, and are designed for long life and durability.

Applications

Due to its rugged construction, corrosion resistance, and general reliability these limit switches are used in a wide variety of applications, from industrial process control, to safety systems and alarms. They are often used to stop machinery that has reached an unsafe position, turn off alarms and lights, or to trigger other events at predetermined locations.

Working Principle

The working principle for the 83261845 snap action, limit switch is relatively straightforward. When the actuator is pressed forward and contacts the contact points, it completes the circuit and the switch is “on.” When it is released, the spring within the switch body pulls the actuator back to its rest position and the switch is “off.” This action is relatively quick and reliable, making it ideal for applications where speed and accuracy are desired.

Conclusion

The 83261845 snap action, limit switch is an incredibly versatile electrical device that can be used in a variety of settings. It is designed to be robust, corrosion resistant and to provide years of reliable service. Its design makes it possible to turn on or off a circuit quickly and accurately, making it well suited for use in industrial process control, safety systems and alarms.
