311SM23-H4

Snap action, limit switches are electrically operated switches used to control the on and off states of a circuit according to the level of an input voltage or current. The 311SM23-H4 is a particularly reliable and precise switch that is well-suited for use in a variety of applications. This article will discuss the 311SM23-H4 application field and working principle.

Application Field

The 311SM23-H4 switch is mainly used in industrial settings, such as mechanical systems, power supplies, process control systems, and HVAC (heating, ventilation and air conditioning). The switch is durable and provides a long service life, which makes it well suited for demanding applications. It is also capable of withstanding high temperatures, high voltages, and rapid changes in pressure or temperature, making it suitable for use in difficult environments.

Working Principle

The 311SM23-H4 utilizes a snap-action system to ensure reliable operation. The switch has a contact arm that is held in place by a leaf spring. When the contact arm is energized, the leaf spring is compressed and rapidly opens the circuit. When the current is removed, the leaf spring automatically expands, restoring the contact arm to its original position and closing the circuit.

The switch is designed to open the circuit at a specific voltage or current level. Once the corresponding level is reached, the contact arm snaps open and breaks the circuit, preventing any further current or damage to the system. The 311SM23-H4 is specifically designed to open the circuit at a high voltage or current level, making it suitable for use in applications where protection from high energy levels is vital.

Conclusion

The 311SM23-H4 is a reliable and precise snap action, limit switch. It is designed to open the circuit at a high voltage or current levels, making it well-suited for use in industrial settings such as process control systems and HVAC systems. The switch is durable and capable of withstanding high temperatures, high voltages and sudden changes in pressure or temperature. Its snap-action system ensures reliable operation and it provides a long service life, making it a reliable and cost-effective solution for a variety of applications.
