MX Switch Tester Keychain

The YINGHUA MX Switch Tester Keychain is a compact gadget that holds four genuine Cherry MX style switches in a clear ABS housing. It lets keyboard enthusiasts feel the distinct clicky, tactile and linear actions before committing to a full board. A lobster clasp secures it to a bag or keys for on-the-go comparison.

Four switch feel in one tool

The sampler includes MX Blue clicky at 55g, MX Black linear at 55g, MX Red linear at 45g and MX Brown tactile at 45g. Each switch uses copper click leafs and softer plastic stems for a smooth stroke. Pressing each key repeatedly reveals how the actuation force and feedback behave during extended typing sessions rather than a single tap.

Silent pocket companion

No LED or active cooling means the keychain adds no noise or power draw in daily use. The clear hard plastic body measures 2cm by 2cm by 2.8cm and weighs almost nothing, so it stays unobtrusive on a keyring. Thermals are irrelevant because there are no electronics to generate heat.

Questions about this item

Does the tester make an audible click or stay quiet when pressed all day?

Two of the four switches — MX Blue and MX Brown — produce a click; MX Red and MX Black are linear and silent.

What keycap stems fit the MX Switch Tester Keychain so I can use my own caps?

All four stems accept standard MX‑compatible keycaps, so any MX‑stem cap will snap on.

Will the 45 g MX Red and 55 g MX Black feel different from the vintage MX switches I already own?

The tester includes both 45 g linear and 55 g linear options, letting you compare actuation force directly against older MX switches.
