What Is an Intercom Metal Dome Array & How Does It Work?
An intercom metal dome array is a set of tactile metal domes (snap domes) mounted on an adhesive sheet, designed specifically for intercom systems. It acts as a momentary switch contact, enabling reliable button operation for intercom communication.
When a user presses an intercom button, the metal dome collapses, making contact with the intercom PCB to send a signal. When released, the dome springs back to its original shape, breaking the contact—ensuring quick, responsive operation every time.
Our intercom metal dome arrays are engineered to work seamlessly with all types of intercom systems, from small residential units to large commercial and industrial intercom setups.
How to Select the Right Intercom Metal Dome Array?
Selecting the right intercom metal dome array starts with understanding your intercom system’s requirements. Focus on three key factors: trip force, size, and compatibility with your PCB.
- Trip Force: Choose a trip force that matches your intercom’s use case—100-200g for light-touch intercoms (residential), 200-350g for standard commercial intercoms, and 350-500g for heavy-duty industrial intercoms.
- Size: Ensure the dome array fits your intercom’s PCB layout. EBest offers standard sizes (8mm, 10mm, 12mm) and custom sizes to match your specific design.
- Compatibility: Verify that the array’s adhesive and mounting style work with your intercom’s PCB or flex circuit. Our peel-and-place arrays are compatible with most intercom PCB designs, simplifying assembly.
Key Applications of Intercom Metal Dome Array
Intercom metal dome array is used in a wide range of intercom systems across multiple industries. Below are four popular industries and real PCB application cases from EBest.

Result: The arrays ensured clear signal transmission even in noisy airport environments, with zero button failures over 6 months of continuous use.
- 4. Residential Intercom Systems (Homes & Gated Communities)
Case: A residential intercom brand needed a compact, light-touch intercom metal dome array for their smart home intercoms. EBest delivered an 8mm array with 150g trip force and custom adhesive.
Result: The compact design fit the client’s small PCB layout, and the light touch improved user experience—boosting the product’s market competitiveness.
How EBest Ensures Intercom Metal Dome Array Reliability
Reliability is critical for intercom metal dome array, as intercom systems often operate 24/7 in various environments. EBest uses a three-step approach to ensure maximum reliability.
First, we use high-grade stainless steel (SUS301) for all domes, which offers excellent elasticity and corrosion resistance—ideal for long-term use in intercom systems.
Second, we implement strict quality control at every production stage, from raw material inspection to stamping, assembly, and final testing. Every array undergoes 100% contact resistance and trip force testing.
Third, we conduct environmental testing (temperature, humidity, vibration) to ensure the arrays perform reliably in harsh conditions—matching the requirements of GJB 150A for environmental adaptability.
Standard vs Custom Intercom Metal Dome Array: What’s the Difference?
Choosing between standard and custom intercom metal dome array depends on your project’s specific needs. Below is a detailed comparison to help you decide.

How to Assemble Intercom Metal Dome Array on PCB
Proper assembly ofintercom metal dome array on PCB is critical for performance and reliability. Follow these simple steps to ensure correct installation.
- 1. Clean the PCB surface: Use isopropyl alcohol to remove dust, oil, or debris—this ensures strong adhesion between the array and PCB.
- 2. Peel the release liner: Gently peel the liner from the array, taking care not to touch the adhesive or domes (fingerprints can reduce adhesion).
- 3. Align and press: Align the array with the PCB’s contact pads, then press firmly across the entire array to ensure all domes are properly seated.
- 4. Test: After assembly, test each dome to verify tactile feedback and contact continuity—this ensures the array works correctly with your intercom system.
