Snap action, limit switches are electromechanical devices that are used to sense the presence or absence of an object. The LSYFC7L3 is a type of limit switch that can be used in a wide range of applications. This article will provide an overview of the construction, application field and working principle of the LSYFC7L3.

Construction of the LSYFC7L3

The LSYFC7L3 is a single pole, double throw switch with a mechanical and electrical latching service. It is rated for up to 15A resistive load, 3A inductive load, 1kVac dielectric strength and 5A 125Vac and 3A 250Vac. The switch is constructed out of a plastic enclosure, stainless steel actuator and a gold-plated contact surface. The actuator is rated for 500 million mechanical operations, which makes it extremely reliable for long-term applications.

Applications of the LSYFC7L3

The LSYFC7L3 is suitable for a variety of applications. Its long life and robust form factor make it ideal for applications in hostile environments. It is often used as a relay switch in motor controller applications, or used in HVAC systems to control low-voltage loads. Its reliable snap action and gold-plated contacts make it useful for a variety of other applications such as automotive control systems, exhaust systems and lighting control.

Working Principle of the LSYFC7L3

The LSYFC7L3 operates by using an internal spring-loaded plunger to make contact with an actuator. When the plunger is triggered by an object, the contacts are closed, allowing current to flow. The force required to close the contacts of the switch can be adjusted using a screwdriver or other tool.

When the object is removed, the plunger is pushed away from the actuator and the contacts are opened. The switch will then stay in the open position until the plunger is triggered again by an object. The LSYFC7L3 is designed for long-term reliability and can handle up to 500 million mechanical operations.

In summary, the LSYFC7L3 is a robust single-pole, double-throw limit switch ideal for use in hostile environments. It is rated for up to 15A resistive load and is suitable for a variety of applications including motor controllers, HVAC systems, automotive control systems and lighting control. The LSYFC7L3 operates by using an internal spring-loaded plunger to make contact with an actuator and is rated for up to 500 million mechanical operations.
