The underside of a keycap contains a mount that connects it to the switch. Many mechanical keyboards use the cross-shaped mount associated with Cherry MX and compatible MX-style switches.
How to identify an MX-style stem
Gently pull off one ordinary letter key using a keycap puller. The switch stem should have a visible cross shape. Check the keycap underside as well: its socket should be shaped to fit that cross.
MX-style does not mean every keyboard fits
Matching the stem only confirms the basic connection. You must still verify the spacebar, stabilizers, and key sizes. Large keys use additional mounting points, and compact keyboards can use nonstandard modifiers even when their switches are MX-style.
Low-profile exceptions
Low-profile switches often use a different stem height, spacing, or mount design. Some may look similar from above but still require dedicated low-profile keycaps. Do not force a keycap onto a stem that does not align easily.
Proprietary systems
Some keyboards use scissor mechanisms, membrane plungers, optical designs, or proprietary mounts. Laptop-style keycaps are generally not interchangeable with standard mechanical-keyboard keycaps.
The Strawberry Cat set is designed for standard MX-style cross stems and is not specified for low-profile systems. If you are unsure, remove one ordinary keycap and compare the plus-shaped mount described in our compatibility checker before reviewing the set in Shop Keycaps.
