UB25RKW035D-DD

Pushbutton switches are an extremely versatile range of switches. Their applications range from simple momentary switches for use in low-power circuits and computers, to complex applications where a combination of momentary, latching and illuminated switches are required. An example of this is the UB25RKW035D-DD switch – a specialist highly versatile switch typically used in industrial applications.

UB25RKW035D-DD Application Field

The UB25RKW035D-DD, marketed and supplied by ZF Engineering, uses designs to allow it to provide quick and reliable switching of high-power electrical circuits and loads. As such, it can be used across a wide range of industrial applications in sectors such as lighting, security, and manufacturing. Its push button nature makes it an ideal choice for applications where a switch needs to be operated quickly, such as emergency stop applications.

Working Principle

The UB25RKW035D-DD has a single-pole, double-throw (SPDT) operating principle. This means it can switch one circuit between two states, such as ON/OFF, or OPEN/CLOSED. At the heart of the switch is a spring-loaded plunger, with a pair of angled teeth at the bottom. When the plunger is pushed in, the teeth move an internal contactor, switching the circuit. On release, the switch moves back to its starting position and the circuit switches back.

Additional Features

In addition to its simple switching principle, the UB25RKW035D-DD also boasts several additional features that make it well-suited to industrial applications. Firstly, it is rated for high currents, with an electrical rating of up to 250V AC 10A, and a mechanical life of more than 5 million operations. It is also supplied with a sealed plastic enclosure, offering IP55 protection from dust and splashing water. Other features include a keylocking function to ensure that the switch cannot be operated or changed without the key.

Conclusion

The UB25RKW035D-DD pushbutton switch is an ideal solution for a wide range of high-power switching applications. Its simple SPDT working principle, combined with its high current rating and keylocking feature, make it highly suitable for use in industrial and manufacturing environments. With its added protection from dust and splashing water, it is one of the most robust switches on the market.
