WL01SD-LD Application Field and Working Principle

What is snap action limit switches?

Snap action limit switches are electromechanical device that can detect the presence of certain substances and are used to control electrical circuits and systems. They are commonly found in industrial and automotive applications and can be used to switch between two or more states, either open or closed, depending on the position or pressure of a specific contact. Snap action limit switches often come with contact form, rating, housing material, operating temperature, and number of positions.

What is the WL01SD-LD application field?

The WL01SD-LD snap action limit switch is a single-pole, double-throw (SPDT) switch with a bounce-free action. This switch is primarily used for HVAC, control panels, fire protection systems, and other applications involving low voltage. It has special features that make it especially suitable for outdoor use and dust-proof applications. With a triple sealing system, and a special internal design, the switch is dust-proof, water-proof, shock-proof, and corrosion-resistant, providing reliable and durable performance.

What is the WL01SD-LD working principle?

As the WL01SD-LD snap action limit switch is a SPDT switch, it works like two switch contacts that are mechanically and electrically connected together when moved. The switch has two terminals; one is connected to the outside world while the other is connected to the internal circuitry of the device. When the actuator is turned, the contacts move and the switch will automatically open and close the circuit, allowing an electrical current to flow through it.

The snap action of the WL01SD-LD switch is its most important feature, as it provides fast and precise action. This snap action ensures that the switch is capable of performing accurately without any jitter or bounce, making it ideal for quick and precise applications. The internal design of the switch also ensures that the contacts are shielded from dust and moisture, so the switch is not affected by environmental conditions.

Conclusion

The WL01SD-LD snap action limit switch is a single-pole, double-throw (SPDT) switch designed for industrial and automotive applications. It is dust-proof, water-proof, shock-proof, and corrosion-resistant, ensuring reliable and durable performance even in the toughest conditions. With its quick and precise snap action, the switch can be used to switch between two or more states, either open or closed, depending on the position or pressure of the contact.
