Electro-capacitive keyboard sound

Topre 45g Sound

Topre uses a capacitive, non-contact sensing mechanism rather than the metal-contact design found in conventional MX-style switches. REALFORCE documents 45g as one of its standard key press force options, while Keysloom's audio profile is based on an attributed generic Topre recording rather than a claim that one browser sample represents every 45g board.

What does Topre sound like?

The Keysloom Topre profile emphasizes a soft, rounded downstroke with an airy midrange and less sharp attack than a clicky MX switch. Real Topre boards vary with case construction, silencing rings, keycaps and model generation, so the simulator is best treated as an acoustic reference rather than a laboratory-identical reproduction.

What does 45g mean on a REALFORCE keyboard?

REALFORCE lists 45g, 30g and variable-weight configurations for its Topre capacitive keyboards. Current 45g models also document 4.0 mm key travel and the Topre capacitive non-contact switch mechanism. See the official REALFORCE mechanism overview for the manufacturer's description.

Topre vs tactile and clicky mechanical switches

Compared with Holy Panda, Topre is represented here as softer and more diffuse through the midrange. Compared with Cherry MX Blue, it avoids the bright, separate click event and instead produces a rounded electro-capacitive character.
