Materials Used to Make a 44mm Square Illuminated Push Button with LED for Arcade Game Machines

The 44mm square illuminated push button is a critical user interface component in arcade machines, combining functionality, durability, and visual appeal. Constructed from a variety of specialized materials, each element plays a vital role in ensuring the button performs reliably under high-use conditions while contributing to the vibrant, engaging aesthetic of the arcade environment. Understanding the materials used in its construction helps in selecting high-quality components for both commercial and custom builds.

Core Materials and Their Functions

Plastic (Acrylic & Polycarbonate)

Plastic forms the primary visible component of the illuminated button—its cap—and is typically made from high-quality thermoplastics such as acrylic (PMMA) or polycarbonate (PC). These materials are favored for their excellent optical clarity and ability to diffuse LED light evenly across the surface, creating a bright, uniform glow that enhances visibility and visual impact.

Polycarbonate, in particular, offers superior impact resistance and flexibility, making it ideal for arcade environments where buttons are frequently pressed with force. Acrylic provides a crisper, more polished look with excellent light transmission but is more prone to cracking under extreme stress. Both materials are lightweight, corrosion-resistant, and can be easily injection-molded into precise 44mm square shapes with custom textures or finishes.

Additionally, plastics are available in a wide range of colors and opacities, enabling customization for different game functions (e.g., red for attack, green for start). Their low production cost also makes them ideal for mass manufacturing without sacrificing aesthetic quality.

Metal (Stainless Steel & Aluminum)

The button's housing or bezel is often constructed from metal—typically stainless steel or aluminum—to provide structural support and enhance durability. Stainless steel is highly resistant to corrosion, scratches, and wear, making it perfect for arcade cabinets in public spaces where hygiene and longevity are essential, such as arcades, casinos, or amusement parks.

Aluminum offers a lighter alternative with good strength-to-weight ratio and natural oxidation resistance. It is often anodized to improve surface hardness and allow for color matching with the machine’s design. Metal housings also provide electromagnetic shielding and help dissipate heat generated by the internal LED, contributing to longer component life.

While more expensive than plastic, metal components convey a premium feel and significantly increase the button’s lifespan, especially in high-traffic installations where thousands of presses occur daily.

Conductive Materials (Copper Alloys & Spring Contacts)

Inside the push button, conductive materials such as copper alloys, phosphor bronze, or beryllium copper are used in the contact mechanism to ensure reliable electrical connectivity. When the button is pressed, these metal contacts close the circuit, sending a signal to the game’s control board.

Copper alloys are chosen for their excellent electrical conductivity, mechanical resilience, and resistance to arcing and oxidation. Many designs incorporate spring-loaded contacts that provide tactile feedback and ensure consistent activation. These internal components must endure millions of actuations without significant wear, making material quality crucial.

High conductivity reduces resistance and heat buildup, minimizing the risk of failure during extended gameplay. For illuminated buttons, conductive traces may also route power to the integrated LED, requiring careful insulation and layout to prevent short circuits.

Rubber Seals (Silicone & EPDM)

To protect against dust, moisture, and accidental spills—common hazards in arcade environments—rubber seals are integrated around the base of the button. Silicone rubber is the most commonly used material due to its exceptional flexibility, temperature resistance (-50°C to 200°C), and long-term durability without hardening or cracking.

These seals create a watertight barrier between the button and the control panel, preventing contaminants from reaching internal electrical components. This is especially important for outdoor cabinets, redemption games, or locations with high humidity.

In addition to environmental protection, rubber gaskets help dampen vibrations and reduce noise during button presses, improving the overall user experience. Ethylene Propylene Diene Monomer (EPDM) rubber is sometimes used as a cost-effective alternative with good weather resistance, though it may not last as long as silicone in demanding applications.
