KH-PB-22E70-WS Six-Pin Momentary Push Button Switch: Control the Circuit in a Tiny Space

2026-10-20 205

I. Product Overview
In the design system of modern electronic equipment, push button switches are the most basic and core components for human-machine interaction. A tiny button carries the task of circuit on/off and function switching. Its stability, feel, and structural design directly affect the user experience and service life of the entire product. Kinghelm (Jinhangbiao), a well-known domestic manufacturer of RF and connector components, has launched the KH-PB-22E70-WS six-pin momentary push button switch. With its compact structure and reliable electrical performance, it has become a preferred component in consumer electronics, industrial control equipment, and smart hardware, providing convenient and stable control solutions for various PCB circuit designs. KH-PB-22E70-WS is a 5.8 x 5.8 x 13.5H mm through-hole plug-in push button switch. Each unit has a gross weight of only 0.49 g. It is small and lightweight, allowing installation and layout within limited circuit board space. The product is packaged in bags, making it suitable for mass production stocking and well suited to factory through-hole insertion assembly line requirements. Kinghelm KH-PB-22E70-WS product image.

II. Core Features
This switch adopts through-hole mounting and PC (polycarbonate) pins, making it sturdy and reliable. It is compatible with both manual soldering and wave soldering processes. After soldering, the pins are tightly combined with the PCB substrate, providing outstanding resistance to vibration and impact, making it suitable for equipment used in vibration environments. In terms of circuit structure, KH-PB-22E70-WS has a double-pole double-throw (DPDT) structure and can simultaneously control two independent circuits for synchronous switching. Compared with single-channel switches, the DPDT structure expands circuit design possibilities. In scenarios requiring synchronized switching of two signal paths or isolated control, a single button can complete the on/off operation of two circuits, simplifying PCB routing, reducing the number of components, and saving circuit board space. Button style: rectangular plunger, white keycap with black base, simple appearance, and clear and crisp pressing feedback. Locking type: momentary type, contacts close when pressed and automatically reset when released. Unlike a latching switch, it is suitable for jog or momentary trigger scenarios. Illuminated version: this model is non-illuminated, resulting in a simpler structure, lower power consumption, fewer LED failure points, and improved long-term reliability.

III. Structural Design Details
The 5.8 mm x 5.8 mm base size is an industry-standard compact specification. The 13.5 mm total height leaves ample margin for equipment panel design, allowing the keycap to protrude from the enclosure for easy operation by users. The six-pin layout is the standard arrangement for DPDT circuits, and the pin spacing is standardized. Common PCB footprint libraries can be used directly. Hardware engineers do not need to redraw the footprint during schematic and PCB design, effectively shortening the R&D cycle. The internal spring contacts and contact points of the switch are made from strictly selected materials, ensuring stable electrical contact under repeated pressing, reducing common failures such as contact resistance drift and poor contact, and extending product service life.

V. Brand and Quality Assurance
Kinghelm (Jinhangbiao) relies on its modern production base in Luzhai, Guangxi, and intelligent flexible production lines to build end-to-end one-stop development capabilities covering product design, mold development, performance testing, and mass production. It has established a complete quality control system covering raw material screening, mold processing, and finished product inspection, enabling stable delivery with large volume, high consistency, and short lead times. Its KH-PB-22E70-WS push button switch undergoes multiple rounds of mechanical pressing tests and on/off performance testing before leaving the factory, fully ensuring the performance stability of each batch. Compared with imported similar devices, it has significant advantages in lead time, procurement cost, and localized technical support, comprehensively helping the domestic electronics manufacturing industry reduce costs and increase efficiency.

VI. Conclusion
The value of electronic components is often hidden in the details. With its compact size, mature DPDT circuit structure, and convenient through-hole mounting solution, KH-PB-22E70-WS meets the momentary control needs of many products. As the consumer electronics and intelligent equipment industries continue to develop, domestic component brands such as Kinghelm continue to refine basic components and continuously optimize switch feel and structural reliability, providing stable and reliable domestic options for China's electronics industry. A tiny button may seem inconspicuous, but it is the starting point for interaction in countless electronic products. It completes circuit opening and closing in a tiny space and supports the stable operation of thousands of devices.
