KH-PB-22E65 Push Button Switch: 5.8 mm Six-Pin Latching Design for Ultra-Compact PCB Applications

1. Product Overview: Compact Size, Reliable Performance for High-Density PCBs

As PCB space becomes increasingly limited, the footprint of each component plays a critical role in determining how much functionality can be integrated into a circuit board. The Kinghelm KH-PB-22E65 is designed specifically for applications with stringent space constraints.

With a compact footprint of just 5.8 mm × 5.8 mm and an overall installed height of 10.7 mm, this switch is one of the most compact options in its series of through-hole latching switches. It provides a reliable state-retention solution for high-density PCB layouts and applications with limited installation space.

3. Six-Pin Latching Mechanism for Convenient State Retention

Unlike conventional momentary switches, the KH-PB-22E65 features a latching mechanism. A single press locks the switch in the ON state without requiring continuous pressure. Pressing it again releases the latch and returns the switch to the OFF state.

This mechanism is particularly suitable for applications that require the current operating state to be maintained, including power switching, mode selection, and function activation or deactivation. It simplifies control logic while providing clear, tactile feedback during operation.

The six-pin DPDT configuration offers greater contact flexibility, allowing two separate circuits to be controlled independently. This enables multiple signal-switching functions to be integrated into a single compact switch, helping conserve valuable PCB space.

4. Structural Design and Manufacturing: Attention to Every Detail

According to the engineering drawings, the KH-PB-22E65 uses carefully selected materials to balance durability, mechanical strength, and electrical performance.

• Actuator head: POM and phosphor bronze

• Switch cover: POM (polyoxymethylene), also known as acetal resin

• Main housing: Nylon fiber-reinforced construction with brass reinforcement

• Internal spring and worm mechanism: Stainless steel wire

• Surface finishes: Silver plating and nickel plating

The switch features a non-shorting (break-before-make) contact design, helping prevent momentary short circuits between contacts during switching and improving circuit protection.

Its compact, approximately 6 mm-class package and through-hole mounting design provide stable mechanical attachment and compatibility with conventional PCB assembly processes, including wave soldering, subject to the applicable process specifications.
