General Knob Boeing 737: The Essential Replica for Flight Enthusiasts and Schools

Step into the world of aviation simulation with the General Knob Boeing 737, the most common and essential control element used in the Boeing 737 cockpit. Designed specifically for flight enthusiasts and commercial flight schools, this replica knob brings unparalleled realism and tactile feedback to flight simulators, enhancing training and hobby flying experiences.

Every Boeing 737 cockpit typically requires 25 of these knobs, highlighting their fundamental role in aircraft controls. Crafted with precision, this knob fits seamlessly onto rotary switches, potentiometers, or encoders with a 6mm hole, and is also available with a D-Shaft hole to match your specific simulator setup. Whether you’re adjusting frequencies or fine-tuning settings, the rotary switch knob ensures smooth, consistent control.

Quality Craftsmanship in Every Detail

Our 3D printed resin general knob boasts exceptional optical quality and a superior haptic finish, providing the tactile authenticity that pilots demand. The use of resin printing allows for sharp definition in the knob’s design, truly mirroring the look and feel of an original Boeing 737 knob. This attention to detail transforms your cockpit or simulator into a professional-grade setup.

The knob features an iron gray exterior complemented by black and white infill colors, perfectly replicating the cockpit’s authentic control aesthetics. With a base diameter of 24mm, it fits comfortably in hand, providing intuitive control over your rotary switches.

Designed for Easy and Secure Installation

Installation couldn’t be easier. Each knob includes a headless Allen screw for mounting on your device’s shaft, ensuring a secure fit. However, for added stability, we recommend using hot glue during mounting—giving you a reliable, durable hold even during intense simulation sessions.

This feature makes the knob compatible not only with potentiometer and encoder shafts but also ideal for applications requiring a secure fit on D-Shaft designs. Whatever your cockpit’s wiring and shaft configuration, this knob adapts smoothly, making upgrading your simulator controls straightforward and efficient.

Why Choose This Boeing 737 Knob Replica?

  • Authentic Feel: Experience the same precise grip and control as in a commercial Boeing 737 cockpit.
  • Versatile Mounting: Fits rotary switches, potentiometers, encoders, and D-Shafts with included Allen screw and hot glue recommendation.
  • Superior Build: Resin 3D printing provides detailed finish, durability, and a professional look.
  • Accurate Size: 24mm base diameter for optimal hand placement and control.
  • Visually Accurate: Iron gray coloration with black and white infill replicates the original knob’s appearance.

Frequently Asked Questions (FAQs)

Q1: Will this knob fit all rotary switches used in flight simulators?

A: The General Knob Boeing 737 is designed with a 6mm hole to fit most rotary switches, potentiometers, and encoders. We also offer a version with a D-Shaft hole to accommodate different shaft designs.

Q2: How should I mount the knob to ensure it doesn’t come loose?

A: Each knob includes a headless Allen screw for secure attachment. For the strongest hold, we recommend applying a small amount of hot glue during installation—this prevents slipping even under extended use.

Q3: What materials are used, and how does this affect durability?

This knob is crafted via resin 3D printing, which ensures both excellent surface detail and sturdy durability. The resin material withstands regular use while maintaining a quality finish and feel.

Q4: Can this knob be used in commercial flight school simulators?

Yes! Its high-quality design and authentic feel make it perfect for both professional training environments and personal flight simulation setups.

Q5: Does the color accurately match the real Boeing 737 knobs?

Absolutely. The iron gray surface with black and white infill precisely replicates the authentic Boeing 737 cockpit control look.

Panel Only

This set includes the front and back panels, all annunciators, knobs, and switch guards.
Note: No electronic components are included. You will need to purchase switches, toggle switches, rotary switches, encoders, or potentiometers separately.

Connect and Play

This is a fully functional unit that must be connected via the IDC connector pins on the back of the PCB to a controller board. Programming is required.
Pin layout information is either printed on the PCB or provided in a separate datasheet.

Plug and Play

This version comes pre-programmed and USB-ready for use with your preferred flight simulation software.
Simply plug it in, install the provided configuration files, and you’re ready to fly!

Power Supply Note:
Because the panels can be daisy-chained using their power connectors, single-panel products do not include a 12V power adapter. Only one adapter is required to power your entire custom cockpit setup. The power supply is used solely for the backlighting, not for the product’s core functions.

Knobs

All knobs are high-quality, resin 3D-printed components with realistic designs. They are supplied with a D-shaft fitting.
