Snap Action Limit Switches

50071756-002-00 switches are a type of snap action limit switch. These devices are used to sense the presence, absence, proximity, or a change in a mechanical edge. Commonly used in industry to detect the travel of a range of materials, such as paper and fabrics, they are also used to detect the operation of a movable member. The lower contact of the snap action switch is movable and when in contact with the upper contact, it completes an electrical path.

Design & Applications

The design of 50071756-002-00 switches are typically compact and can be used in various operations. The switch works by being pushed to a predetermined point where it triggers an electrical connection or current. This allows them to be used in a variety of applications such as industrial automation, robotics, medical and scientific, and domestic appliance appliances. Some examples of their applications include operating elevators, positioning of machine tools, detecting a range of materials and fabrics, and controlling safety devices.

Advantages and Limitations

Snap action limit switches are known for their advantage over alternative switch types in terms of contact stability, reliability, and performance and have the ability to operate without interruption over millions of cycles. As with any contact switch, however, it may start to wear down over time due to mechanical/surface contact stress and frequent operation. Additionally, the contact may become contaminated with dust, water, and other particles, which can also cause the switch to wear out prematurely.

Working Principle

The 50071756-002-00 snap action switch uses two electromagnets within its assembly. These electromagnets create a field that pulls the moveable contact located in the switch downward when activated. When the switch is switched on, the lever arm pushes the contact out (down), thereby completing the circuit and making the switch operational. In a typical switch, the current flows through the switch from one electrode to the other, creating a magnetic field that activates the lever arm. As the current is repeatedly switched on and off, the switch opens and closes the circuit, allowing operation when the switch is engaged.

Conclusion

The 50071756-002-00 snap action switch is an ideal solution for a variety of applications that require sensing and control. Its compact design and reliable performance make it a popular choice for industrial automation, medical and scientific, and domestic appliance appliances. However, they may be subject to wear with frequent use, as well as contamination, so proper maintenance is essential to ensure effective performance over time.
