Snap action, limit switches are electromechanical devices used to limit the travel of a machine part or to detect the presence of an object. These devices typically feature two contacts, each of which functions when activated by an external force. When this force is applied, the contact moves and creates a discrete electrical connection between the two contacts. The WW2K29H-D9 snap-action, limit switch utilizes this basic design but employs some unique features to create an accurate and reliable switch.

Primary Features

The WW2K29H-D9 is a low-profile snap-action, limit switch designed for use in applications that require high precision and reliability. It is designed with a protruding plunger, operated by a spring-loaded actuator. This ensures that the switch can convert electromagnetic signals without fail, even in extreme conditions. It also contains various mechanisms to detect and respond to vacuum and shock, providing an accurate and reliable switch even in hostile environments.

Construction

The WW2K29H-D9 is constructed from a single housing which houses its various components. These components include the main contact plunger, contact subassembly, and actuator. The plunger is connected to the contact subassembly by a spring-loaded actuator. When the plunger is activated, it causes the contact subassembly to move and create a discrete electrical connection between the two contacts. The actuator is connected to a series of dampeners which absorb any shock transmitted through the plunger.

Design Specifications

The WW2K29H-D9 features a maximum operating temperature of 71 °C, a rated voltage of 24 DC V, and a rated current of 1 A. It has a contact resistance of 50 mΩ, an insulation resistance of 100 MΩ, and a dielectric strength of 500 V. The switch also has a surge voltage of 3 kV, a surge current of 20 A, and a mechanical life of 500,000 cycles. The device is rated for use in a variety of industries, including automotive, industrial and consumer.

Performance

The WW2K29H-D9 is designed for reliable performance in both demanding and less harsh environments. The device features a high contact current of 1 A and a high contact voltage of 24 DC V. The switch also offers reliable and accurate electrical isolation performance and can be used in a variety of applications, including low voltage and electric door locks. Additionally, this switch has an excellent switching performance even in hostile environments, such as high shock and vibration environments.

Conclusion

The WW2K29H-D9 is an exceptional snap-action, limit switch designed for reliability and accuracy in a range of applications. The device features a low-profile design, with a protruding plunger, operated by a spring-loaded actuator, and various mechanisms for detecting vacuum and shock. Additionally, the switch offers high contact current and voltage ratings, as well as reliable and accurate electrical insulation performance. With its high performance, this device is perfect for industrial, automotive and consumer applications.
