How To Open Mechanical Keyboard Switches Safely?

Opening a mechanical keyboard switch is a simple process once you understand the parts involved. You need the right tool, a steady hand, and a clear view of the switch’s clips. With a switch opener, you can separate the top housing from the bottom housing in seconds without damaging the delicate metal leaf contacts inside.

What You Need Before You Start

The most important tool is a proper switch opener. These come in two basic forms: a two-pronged metal tool that grabs the side clips, and a three-pronged plastic tool that fits over the top housing. Both work well. The two-pronged style is often easier to use on switches still mounted in a keyboard plate.

You also need a flat, clean workspace with good lighting. A soft mat or towel underneath prevents small parts from bouncing away. The switch itself contains a spring, a stem, and two metal contact leaves. These parts are small and easy to lose.

If you do not have a dedicated opener, a flathead screwdriver can work in a pinch. You insert the tip between the top and bottom housing where the clips are located and gently pry. This method carries a higher risk of scratching the plastic or bending the clips, so proceed slowly.

How To Open Mechanical Keyboard Switches Safely

Place the switch on a firm surface with the two side clips facing left and right. Hold the bottom housing firmly with one hand. Insert the opener’s prongs into the gaps on both sides simultaneously. Squeeze the opener handles together and lift straight up.

The top housing should pop off cleanly. If it does not separate, do not force it. Check that both prongs are fully seated in the clip channels. Forcing a stuck switch can snap the clip tabs, which ruins the housing.

Once the top is off, the stem will sit loosely on top of the spring. Lift the stem out and set it aside. Then remove the spring. The two metal leaves remain in the bottom housing. These are the contact points that register keystrokes. Avoid touching or bending them.

For switches with a two-piece bottom housing — common in some premium switches — you can separate the base plate from the bottom housing after removing the leaves. This step is optional and only needed for deep cleaning or stem replacement on those specific designs.

Opening Switches Still Mounted in a Keyboard

Opening a switch while it is installed in a keyboard plate requires a different approach. You cannot use a standard three-pronged opener because the plate blocks access from the sides. A two-pronged opener designed for in-plate use is the correct tool.

These openers slide into the clip slots from the top. The prongs push the clips inward while the tool’s body presses down on the top housing. You then lift the top housing off while the bottom housing stays locked in the plate.

This method is useful when you want to swap stems or springs without desoldering the entire switch. It is also riskier because the plate adds resistance. Work slowly and check that the prongs are aligned before applying pressure.

Some keyboards use plate-mounted switches with no screws. In that case, you must desolder the switch from the PCB before opening it. Never attempt to pry a soldered switch open while it is still attached to the board. You will bend the pins and damage the PCB.

Common Mistakes and How To Avoid Them

The most common mistake is using the wrong opener for the switch type. Cherry MX-style switches have clips on the left and right sides. Some clones, like older Kailh switches, have clips on the top and bottom. Check your switch’s clip orientation before choosing a tool.

Another frequent error is prying from one side only. This tilts the top housing and can snap the clip on the opposite side. Always apply even pressure from both sides at the same time.

Losing the spring is also common. Springs are lightweight and can bounce across a desk easily. Keep a small container nearby to hold each switch’s parts as you work. This also keeps stems and springs from different switches from mixing together.

Bending the metal contact leaves is the most serious mistake. These leaves are thin and fragile. If they bend, the switch will not register presses reliably. If you notice a bent leaf, you can carefully straighten it with tweezers, but replacement is often safer.

What To Do After Opening the Switch

Once the switch is open, you have several options. You can lubricate the stem and spring with a switch lube like Krytox 205g0. Apply a thin layer to the stem’s side rails and the spring’s coils. Avoid getting lube on the metal contact leaves, as this can cause inconsistent electrical contact.

You can also swap the stem to change the switch feel. For example, putting a linear stem into a tactile housing changes the switch’s characteristics. This is a common mod called stem swapping. It works best when the stem and housing are from compatible manufacturers.

Deep cleaning is another reason to open switches. Dust and debris can accumulate inside over time. Use compressed air or a soft brush to remove particles before reassembling.

Reassembly is the reverse of opening. Place the spring in the bottom housing, set the stem on top, and press the top housing down until both clips click into place. Test the switch by pressing it a few times before reinstalling it in your keyboard.

When Opening Switches Is Not Worth the Risk

Not every switch needs to be opened. If your keyboard works fine and you just want a different feel, consider buying pre-lubed switches instead. Many manufacturers now sell switches that come lubricated from the factory.

Opening switches voids warranties on some pre-built keyboards. Check your keyboard’s warranty policy before disassembling anything. If the keyboard is still under warranty, contact the manufacturer first.

If you have never opened a switch before, practice on a few spare switches first. Do not start with the switches in your main keyboard. Buy a small pack of cheap switches to learn on. This reduces the chance of damaging something you rely on daily.

For hot-swappable keyboards, you can remove the entire switch from the board without opening it. Use a switch puller to extract the switch, then open it on your desk. This is safer than opening switches while they are mounted in the plate.

Tools That Make the Job Easier

A dedicated switch opener is worth the small investment. Metal openers are more durable than plastic ones and provide a more precise fit. Look for one that matches your switch type. Most openers work with standard Cherry MX-style switches.

A switch puller is also helpful if your keyboard is hot-swappable. This tool grips the switch from the top and bottom and pulls it straight out of the plate. It prevents bending the pins during removal.

Tweezers with a fine tip help with positioning springs and stems during reassembly. A small brush or compressed air can clean dust from the housing. A soft mat keeps parts from rolling away.

You do not need expensive equipment. A basic opener, a pair of tweezers, and a clean workspace are enough for most switch opening tasks.

Long-Term Care for Opened Switches

Switches that have been opened and lubricated generally last as long as factory-sealed ones. The main risk is damage during the opening process itself. If you handle the parts carefully, the switch will function normally for years.

Re-lubricating switches every few years can restore a smooth feel. The original lube wears down with use. How often you need to re-lube depends on how much you type and the quality of the lube used.

Store spare springs and stems in labeled containers if you plan to do more mods later. Mixing parts between different switch models can change the feel in unpredictable ways. Keeping them organized prevents confusion.

If a switch stops working after you open it, check the metal leaves first. A bent leaf is the most common cause of failure after reassembly. Straighten it carefully or replace the switch if needed.
