WLH2

Snap action, limit switches, or kick switches, are mechanical devices used to detect and initiate a specific action at a given point of mechanical travel. WLH2 is one of the most reliable limit switches available in the market today. In this article, we will take a close look at the WLH2 application field and working principle.

WLH2 Application Field

The WLH2 switch is ideal for use in applications where precise and accurate mechanical actuation is required in temperatures ranging from -10°C to 120°C. It is used in many industrial applications such as automation unit indication, safety controls, press, printing and forwarding machines. Its wide range of alternating current and direct current makes it suitable for the automation of a variety of different devices.

The WLH2 switch is able to function as a single-pole, single-throw switches with a variety of different contact configurations. These include single changeover contacts, double break contacts, double break/changeover contacts, and single break/changeover contacts. The switch also features a wide range of control voltages, from 5 volts to 380 volts.

WLH2 Working Principle

The WLH2 switch uses a snap action mechanism to detect and initiate a specific action at a given point of mechanical travel. When a switch is actuated either by an operator or by a mechanical force, it triggers a solenoid inside the switch. The solenoid then pushes a contact blade, which in turn activates the switch.

The WLH2 switch has a smooth and precise actuation level, with minimal hysteresis. This ensures accurate and repeatable switching action. The mechanical construction of the switch also helps to ensure reliable operation, with a rugged body and durable components.

The WLH2 switch features a robust steel body that is sealed against oil and other contaminants. This helps to ensure reliable operation in applications where a wide variety of chemicals or fluids may be present. In addition, the WLH2 switch can be used in applications where extreme temperatures or shock may be present. The switch also features a low operating current, making it ideal for applications where power consumption is an issue.

Conclusion

The WLH2 switch is an effective and reliable limit switch for a wide range of applications. Its snap action mechanism ensures precise and repeatable actuation, while its robust construction ensures reliable operation in hazardous environments. The wide range of control voltages and contact configurations makes the WLH2 switch a versatile solution for the automation of a wide range of devices.
