Remote Control

Custom Metal Dome for Remote Controls — TV / AC / Set-Top Box Remotes

Consistent tactile feel, 1,000,000+ press cycles and sealed, low-resistance contacts — engineered around your remote control, PCB layout and cost target.

Remote Control Metal Dome — Key Requirements

Remote Control Metal Dome — Key Requirements

Remote controls are pressed hundreds of times a week for 5–10 years, in dusty and oily living-room environments.

Every key must feel identical, respond instantly and survive the full product life — at mass-production cost.

Clear Tactile Feedback

Distinct “click” sensation on press, with uniform and stable actuation force.

Reliable Conductivity

Low contact resistance (typically <1Ω); anti-oxidation surface treatment such as gold plating ensures more sensitive and accurate signal transmission.

Long Service Life

Press-resistant, typically rated for 1,000,000+ cycles without failure.

Fast Rebound

Instant reset upon release, eliminating “press-and-no-return” failure.

Dust & Contamination Resistance

Withstands dust and oil contamination without affecting contact performance.

1,000,000
rated press cycles service life

Common Challenges

Poor Contact – Key failure caused by oxidation, dust, or oil contamination.

Inconsistent Tactile Feel – Process deviations cause varying press force across keys within the same batch.

Sticking / No Rebound – Housing deformation or foreign debris jams the metal dome, preventing proper reset.

Insufficient Lifespan – Inferior materials or processes result in actual cycle life far below the rated value.

PCB Scratching – Burrs on metal dome edges repeatedly abrade and damage the PCB.

Common Remote Control Dome Issues and Solutions

Issue Cause Solution
Key unresponsive Oxidation/contamination on the metal dome or PCB contact point Clean the contact point; use gold-plated/silver-plated metal domes for enhanced anti-oxidation
Key insensitive Excessive contact resistance; metal dome not fully depressed Check dome height vs. PCB gap; use center-point gold-plated domes to lower resistance
Feel becomes too hard/soft Metal dome fatigue deformation; force value outside tolerance Optimize dome curvature design; tighten force tolerance to ±15gf
Dome doesn’t rebound Housing deformation, foreign debris jamming, or dome fracture Inspect housing structure; use high-durability SUS301 material rated for ≥1,000,000 cycles
Intermittent performance Dust/oil contamination entering the gap between dome and contact Use TPU or PET film encapsulation to seal out external contamination
Short lifespan, early failure Inferior material or burrs on stamped edges Use precision full-cut, burr-free metal domes; 100% electrical performance testing on all batches
