LSQA1A278

Snap Action, Limit Switches

LSQA1A278 is a low voltage snap action, limit switch that provides components used in industrial, domestic, and commercial applications. It is characterized by a highly reliable snap action mechanism. It features a momentary electrical contact that remains closed until the specified actuating position is reached, at which point an internal mechanical assembly opens the contact. The switch has a built-in resistor to prevent false triggering in electrical circuits, as well as an adjustable contact gap to suit a variety of requirements.

Operational Principle

The LSQA1A278 works on the principle of a snap action switch. It consists of an actuator accompanied by a plunger and moving contact. When the actuator moves in the desired direction, the plunger is drawn forward, stretching the resilient member inside and storing energy in the form of kinetic energy. When the switch\'s trip point is reached, the plunger releases the energy it stored and moves the contact to the other side. This creates a make or break switch.

Applications

The LSQA1A278 is used in many industrial applications, such as controlling process limits in machine tools, triggering alarms and interlocks in hazardous areas, regulating fans and blowers, and signaling the extent of linear movement in automated assembly systems. It can also be used as part of a safety system to prevent injury to personnel, or to protect equipment from overheating or damage caused by poor machine operation. In addition, this switch is often used to close valves in production or to control pneumatic systems.

Features and Benefits

The LSQA1A278 offers a number of features and benefits that make it ideal for many application types. To begin with, its snap action mechanism is reliable and accurate, ensuring safe and consistent actuation. The contact gap is adjustable, making it easier to tailor the switch to the specific application. It also features a built-in resistor as well as several connection options, making it easier to integrate into existing circuit boards. Furthermore, the switch is slim and compact, making it easier to install into tighter spaces.

Conclusion

The LSQA1A278 is a reliable and versatile snap action limit switch designed for a wide range of applications. It offers reliable and accurate operation, adjustable contact gap, and several connection options. It is also slim and compact and can be easily integrated into existing circuit boards. Furthermore, its built-in resistor prevents false triggering in electric circuits, making it a great choice for industrial and commercial applications.
