North vs South Facing Switches

Keycap Compatibility: The Reason This Matters

The most talked about consequence is keycap compatibility, specifically with a popular sculpted keycap profile that has interference issues. On north facing switches, the internals can collide with the inside of certain tall sculpted keycaps, preventing them from pressing all the way down. South facing switches move that obstruction out of the way, so they avoid the interference and work cleanly with those keycaps.

Why South Facing Is the Safer Default

Because of that, south facing is generally preferred on boards where you might use a wide range of keycap profiles, since it sidesteps the compatibility problem entirely. If your board is north facing, you are not out of luck, but you should confirm that your chosen keycaps clear the switch internals before buying a full set, particularly with the taller sculpted profiles.

LED Position and Backlighting

There is also a lighting consideration. With north facing switches the LED sits nearer the top of the keycap legend, which can light shine through legends more evenly on caps designed for it, while south facing places the LED nearer the bottom. For boards without per key backlighting, this point is irrelevant, and it only matters if legend lighting is important to you.

Sound and Feel: Mostly Overblown

Some people also debate a subtle difference in sound and feel between the two orientations, but this is minor and easily overshadowed by switches, keycaps, and mods. For most buyers the practical rule is simple: if you want the widest keycap compatibility, favor south facing, and if you have a north facing board, just verify keycap clearance before committing to a set. Beyond that, do not let orientation dominate your decision.

Common Questions About Switch Orientation

Is south facing always better? For keycap compatibility, yes. For backlit legends on caps designed for top lighting, north facing can look better. Compatibility matters to more people.

How do I tell if my board is north or south facing? Look at the switch top with the board facing you. If the LED slot and the clear window point away from you it is north facing, toward you it is south facing.

Can I still use Cherry profile keycaps on a north facing board? Often yes, but check clearance before buying a full set. Interference shows up as keys that will not bottom out cleanly.

Does orientation change the typing sound? Slightly, but switches, keycaps, plate material and mounting style all matter far more. It is not worth choosing a board on this alone.

North vs south facing LEDs for RGB and shine-through keycaps

If you care about RGB lighting, the question to ask is where the legends sit on your keycaps. Most shine-through keycaps have legends printed near the top of the key. On a north facing board, the LED sits under that top edge, so light passes through the legend more directly and evenly. On a south facing board, the LED sits toward the bottom of the key, and top-printed legends can look dimmer or unevenly lit.

Without shine-through keycaps, the difference largely disappears. Solid PBT or doubleshot keycaps that do not let light through the legend only show underglow around the edges of the keys, which looks similar on both orientations. Some keycaps place legends on the front face or near the bottom specifically for south facing boards, so check the keycap design if lighting matters to you.

This is the core tradeoff between the two orientations. North facing tends to give better legend lighting with standard shine-through caps, while south facing avoids the interference issue with certain sculpted keycap profiles. Decide which of those matters more for how you will actually use the board.

Can you change switch orientation on a keyboard

Switch orientation is set by the PCB, not by the switch. The hot-swap sockets or solder holes fix where the switch pins go, so you cannot rotate a switch to turn a north facing board into a south facing one. Choosing orientation is effectively part of choosing the keyboard or PCB.

If you already own a north facing board and run into keycap interference, the fix is on the keycap side. Try a different profile, or test a few keys from a set for clearance before buying a full kit. If you want the best RGB legend lighting on a south facing board, look for keycaps with legends positioned to match, rather than trying to modify the board.
