Metal Dome: Bad Clicking Feel And How to Fix It

10 Jan, 2024

By hqt


Metal domes are an essential component in many electronic devices, particularly in keyboards and remote controls. They play a crucial role in providing tactile feedback when a key or button is pressed. However, sometimes users encounter a bad clicking feel when using devices with metal dome switches. In this article, we will explore the reasons behind this issue and provide practical solutions on how to fix it.

Understanding Metal Domes

What Are Metal Domes?

Metal domes, also known as tactile domes or snap domes, are small, circular or domed-shaped pieces made from stainless steel or other conductive materials. They are used as the contact mechanism in many membrane switches.

How Do Metal Domes Work?

When you press a key or button on a device with metal dome switches, the dome collapses, creating an electrical connection. This action registers the keypress and provides tactile feedback, allowing you to feel the actuation point.

Common Issues with Metal Domes

Bad Clicking Feel

One of the most common issues with metal dome switches is the unpleasant clicking feel. Users often describe it as mushy, unresponsive, or inconsistent.

What Causes the Bad Clicking Feel?

Several factors can contribute to the bad clicking feel in metal dome switches:

1. Dirt and Debris

Accumulated dirt or debris between the dome and the membrane can hinder proper contact, leading to a poor clicking experience.

2. Dome Deformation

Over time, metal domes can deform, losing their original shape and tactile properties. This deformation can result in a less satisfying click.

3. Inadequate Design

Improper design or poor-quality materials in the switch assembly can also contribute to a bad clicking feel.

How to Fix the Bad Clicking Feel


Cleaning the metal dome switches is the first step in resolving the issue. Here’s how to do it:

Step 1: Disassemble the Device

Carefully disassemble your keyboard or remote control to access the metal dome switches.

Step 2: Clean the Domes

Gently clean the metal domes using a soft, lint-free cloth or a cotton swab dipped in isopropyl alcohol. Ensure that there is no residue left behind.

Step 3: Reassemble the Device

Put your device back together and test the buttons. You should notice a significant improvement in the clicking feel.

Dome Replacement

If cleaning doesn’t solve the problem, you may need to replace the metal domes. Here’s how:

Step 1: Identify the Dome Type

Determine the type and size of metal domes used in your device. You can usually find this information in the device’s manual or by searching online.

Step 2: Order Replacement Domes

Order replacement metal domes that match the specifications of your existing ones. Make sure to buy high-quality domes from reputable suppliers.

Step 3: Replace the Domes

Carefully remove the old domes and replace them with the new ones following the manufacturer’s instructions. Reassemble your device and test the buttons.

Professional Repair

If you are unsure about cleaning or replacing the metal domes yourself, it’s best to seek professional repair services. Experienced technicians can diagnose the issue and provide the necessary solutions.


A bad clicking feel in devices with metal dome switches can be frustrating, but it’s not an insurmountable problem. By understanding the causes and following the steps to clean, replace, or seek professional repair, you can enjoy a better tactile experience when using your electronic devices.

FAQs (Frequently Asked Questions)

Q: Can I use any type of cleaning solution to clean metal domes? A: It’s best to use isopropyl alcohol, as it evaporates quickly and leaves no residue.

Q: Are metal domes the same in all electronic devices? A: No, metal domes vary in size, shape, and material, depending on the device’s design.

Q: How often should I clean my keyboard with metal dome switches? A: Cleaning your keyboard every few months can help maintain optimal performance.

Q: What if I can’t find replacement metal domes for my device? A: Consult the device’s manufacturer or consider professional repair services.

Q: Is it possible to prevent metal dome deformation? A: While it’s challenging to prevent entirely, using high-quality domes and avoiding excessive force can help prolong their lifespan.
