Snap Action, Limit Switches

Snap action, limit switches are a type of switch that performs tasks when it senses that an object has moved past a certain point. When an object passes through the preset boundary, the contacts inside the switch will close or open, completing a circuit and sending an electrical signal. Snap action limit switches, such as LSR6B-2D, are designed to become operable with very little force, usually by the force of gravity, air pressure, or vibration. They can be used in a wide range of applications, including safety sensors, industrial automation, and home hardware.

Application Field

LSR6B-2D snap action limit switches are designed for such various applications as mechanical equipment, automotive and electronic controls, and wireless communications systems. These switches are also widely used in automation and control systems, where they can perform functions such as position sensing, speed control and over-travel detection. Thanks to its reliable performance, small size and wide range of available models, the LSR6B-2D is one of the most popular snap action limit switches.

LSR6B-2D can be used for a variety of applications, including:

• Industrial machinery control and feedback
• Automotive engine control
• Wireless communication system
• Input/output sensors
• Position and speed control
• Over-travel detection systems

Working Principle

The basic working principle of the LSR6B-2D snap action limit switch is quite simple. Portion of the switch is composed of an actuating arm and a pivoting lever or an actuator arm. The arm is attached to a spring-loaded plunger that runs in an arc, so that when an external force is applied to the plunger, the arm is displaced and the switch is activated. The force required to activate the switch depends on the size and construction of the switch.

When the lever is pressed, the switch opens or closes its contacts, sending an electrical signal corresponding to the position of the switch. The contacts of some switches can be adjusted to make sure the switch is universally compatible with different types of electrical circuits. Depending on the series, the LSR6B-2D has both normally open (NO) and normally closed (NC) contacts.

The LSR6B-2D offers a variety of features, including double-break contacts, sealed construction, and adjustable levers. Its rugged construction ensures reliable performance and long life. The switch can be used in harsh environments, such as mechanical vibration, sudden shock and high temperature.

Conclusion

Snap action limit switches, such as the LSR6B-2D, are widely used in many applications due to their reliable performance, small size and wide range of available models. They can be used to control and feedback industrial machinery, automotive engines, wireless communication systems and many other applications. Thanks to their simple working principle and adjustable contact settings, the switch can be easily adapted to different circuit configurations. It is also highly resistant to mechanical vibration, sudden shock and high temperature.
