KH-PB-22E60 Six-Pin Latching Push-Button Switch: A Compact DPDT Switch with Big Potential

In electronic product design, push-button switches are among the most basic yet critical human-machine interface components. A push-button switch with stable performance and a well-designed structure can have a direct impact on the overall user experience and reliability of an electronic device. Today, we would like to introduce the KH-PB-22E60, a compact six-pin latching push-button switch from Kinghelm.

1. Product Overview

The KH-PB-22E60 is a six-pin latching push-button switch measuring 5.8 × 5.8 × 13.5H mm. It features a through-hole mounting design with PC terminals and is supplied in a bag package. Each switch weighs only 0.495 g. As a non-illuminated push-button switch, it focuses on its core function of controlling circuit connection and disconnection.

• Product Category: Push-Button Switch

• Circuit Configuration: Double Pole Double Throw (DPDT)

• Button Shape: Rectangular Plunger

• Mounting Method: Through-Hole

• Illumination: Non-Illuminated

• Terminal Type: PC Terminals

The KH-PB-22E60 belongs to Kinghelm's KH-PB-22E series. Other models in the same series include the KH-PB-22E65 (5.8 × 5.8 × 10.7H mm), KH-PB-22E70-WS, and KH-PB-22E75-WS. With different heights and specifications ranging from 10.7 mm to 17 mm, the series provides engineers with flexible options for different internal space requirements.

3. Core Technology: DPDT Configuration and Latching Mechanism

One of the most important features of the KH-PB-22E60 is the combination of its Double Pole Double Throw (DPDT) circuit configuration and latching mechanism.

1. What Is DPDT?

A six-pin latching switch is essentially a Double Pole Double Throw (DPDT) switch. The KH-PB-22E60 has two rows of three pins each. The center pin in each row serves as the common terminal (COM), while the two outer pins correspond to the normally open (NO) and normally closed (NC) contacts, respectively. The two rows form two completely independent Single Pole Double Throw (SPDT) switch circuits.

The key advantage of a DPDT configuration is its ability to control two independent circuits simultaneously. Unlike a conventional Single Pole Single Throw (SPST) switch, which simply controls the on/off state of one circuit, a DPDT switch can switch two circuits between different connection states at the same time. This makes the KH-PB-22E60 particularly useful for applications such as direction switching, forward/reverse motor control, and redundant power switching.

2. How the Latching Mechanism Works

"Latching" means that after the switch is pressed, its internal mechanical structure keeps it in the selected position even after the button is released. Pressing the button again releases the latch and changes the switch to the other state.

This Push-On/Push-Off operating mechanism—press once to lock and press again to unlock—is particularly suitable for applications such as main power switches and operating-mode selection switches.

4. Wide Range of Applications

With the combined advantages of a DPDT configuration and a latching mechanism, the KH-PB-22E60 can be used in a wide range of applications, including:

• Main Power Switches: It can be used as a main power switch for electronic equipment and combined with a DC power jack to provide convenient one-touch power control.

• Motor Forward/Reverse Control: The DPDT configuration is naturally suited to polarity-reversal and forward/reverse control of motors.

• Lighting Control and Mode Selection: It can be used in lighting control circuits or for switching between different operating modes.

• Industrial Controls and Test & Measurement Equipment: Applications include manual mode selection for small PLC modules, status resetting for sensor nodes, range-lock functions on multimeters, and trigger-mode selection on oscilloscopes.

• Smart Home and Consumer Electronics: It can be used for locking operating levels on humidifiers, switching brightness modes on small lamps, and similar applications.

• Automotive Electronics and DIY Projects: Its six-pin DPDT configuration is suitable for applications requiring independent control of positive and negative lines, indicator-light circuits, or dual-channel signal isolation. Examples include centralized power control for automotive equipment, DIY power boxes, and main control panels for 3D printers.
  
  

5. Design and Selection Considerations

For hardware engineers selecting the KH-PB-22E60 for PCB designs, the following factors should be considered:

Pin Identification:
The center pin in each row is the common terminal (COM), while the two outer pins serve as the normally open (NO) and normally closed (NC) contacts. The two rows are completely independent switch circuits and are not electrically connected unless they are connected together on the PCB.

Mounting Method:
The KH-PB-22E60 uses through-hole mounting and PC terminals, making it suitable for through-hole PCB soldering. Compared with surface-mount components, through-hole switches offer secure mechanical mounting and a straightforward structure. They are particularly suitable for prototype development, hand soldering, small-batch production, and conventional through-hole assembly processes.

Electrical Performance:
As a low-voltage, low-current control switch, the KH-PB-22E60 can typically support rated voltages ranging from DC 12 V to 50 V and contact currents of up to 500 mA among products in the same series. This makes it suitable for most low-voltage control circuits.
