KH-PB-22E75-WS Push Button Switch: Ultra-Compact 5.8 mm Six-Pin DPDT Design for High-Density PCBs

As consumer electronics and industrial equipment continue to evolve toward slimmer designs and higher integration, a compact and reliable push button switch can make all the difference in fitting every required function onto a PCB. The KH-PB-22E75-WS push button switch from Kinghelm is an ultra-compact through-hole solution designed for space-constrained applications. With a compact footprint of just 5.8 mm × 5.8 mm, it integrates a six-pin double-pole double-throw (DPDT) configuration and a momentary, self-resetting mechanism into a footprint smaller than a fingernail.

2. Construction and Materials: Durability in Every Detail

According to the product datasheet, the KH-PB-22E75-WS features carefully selected materials to support durability and reliable operation.

The base is made of nylon fiber and brass strip, with a gray-silver nickel-plated finish followed by silver plating. The cover is made of black polyoxymethylene (POM), while the actuator head uses POM and C5210R-EH phosphor bronze with a silver-coated surface. The internal spring is made of stainless-steel wire.

This material combination helps provide actuator wear resistance and consistent tactile performance while supporting stable electrical contact and reliable spring return under repeated operation.

The datasheet also identifies three critical dimensions with an asterisk (*) and specifies commonly used dimensional tolerances for through-hole mounting: ±0.1 mm for dimensions up to 1.5 mm, and ±0.2 mm for dimensions greater than 1.5 mm.

3. Why Choose the KH-PB-22E75-WS? Three Key Advantages

1. Compact Size Without Compromising Functionality

With a footprint of just 5.8 mm, this switch is one of the most compact models in its series while retaining the full switching capability of a DPDT configuration. It is particularly suitable for portable devices and densely populated circuit boards where space is at a premium.

2. Reliable Momentary Operation

The momentary, self-resetting mechanism automatically returns the actuator to its original position when released, eliminating the need to manually reset a latched switch. Its non-shorting switching design helps prevent unintended short circuits during switching, supporting safer circuit operation when used within its specified electrical ratings.

3. Convenient PCB Integration

The through-hole design facilitates manual soldering and supports conventional through-hole assembly processes. The rigid PC terminals provide stable mechanical mounting, while the specified dimensional tolerances help engineers plan pad layouts and PCB footprints more accurately during the design stage.

4. Applications and Selection Recommendations

The KH-PB-22E75-WS is suitable for applications requiring dual-circuit switching in extremely limited spaces, including:

• Control panels for portable instruments

• User-interface buttons in consumer electronics

• Compact operating controls for industrial equipment

• Signal-switching circuits requiring reliable manual operation

• High-density electronic assemblies with strict space constraints

When selecting this switch, engineers should pay attention to three key considerations:

1. PCB footprint compatibility: Verify that the PCB hole pattern and pad dimensions match the PC terminal spacing and dimensions.

2. Operating requirements: Confirm that the momentary, self-resetting mechanism matches the intended user interaction and switching frequency.

3. Customization options: If an illuminated version or a different terminal configuration is required, contact the Kinghelm engineering team to discuss available options.
   
   

5. Conclusion

The design quality of electronic components is often most evident in the smallest details. By combining an ultra-compact footprint, a six-pin DPDT configuration, and a momentary, self-resetting mechanism, the KH-PB-22E75-WS provides a practical balance of space efficiency and switching functionality for high-density PCBs.

For consumer electronics and industrial applications that require a compact, dependable, and easy-to-integrate push button switch, the KH-PB-22E75-WS is well worth considering.
