The Cherry MX Silent switches (MX Red variation) have an actuation force rating of 45 cN and those of our sample averaged at 45.6 cN. The Corsair Gaming Strafe RGB Mechanical Gaming Keyboard is exceptionally consistent, with a disparity of just ☓.08%. It is good to see that the modifications that Cherry made to create the MX Silent switch did not affect their quality. Still, very low figures on medium sized keys, such as the Shift and Enter keys reveal design issues and can easily be perceptible by the user. For this reason, we do display the force required to actuate every key but we only use the results of the typical sized keys for our consistency calculations. This is natural, as the size and weight of the keycap reduces the required actuation force. Note that large keys generally have a lower actuation force even if the actuation point is at the dead center of the key. Enter, Space Bar, etc.), the measurement is taking place at the center of the key, right above the switch. The machine we use for our testing is accurate enough to provide readings with a resolution of 0.1 cN. It is worth noting that there is typically variance among keyboards, although most keyboard companies will try and maintain consistency - as with other reviews, we're testing our sample only. Greater differences are likely to be perceptible by users. A high quality keyboard should be as consistent as possible, with an average actuation force as near to the manufacturer's specs as possible and a disparity of less than ☑0%. The conversion formula is 1 cN = 1.02 gf (i.e. Some companies use another figure, gram-force (gf). The actuation force is measured in Centinewton (cN). It can also reveal design issues, such as the larger keys being far softer to press than the main keys of the keyboard. By measuring the actuation force of every key, the quality and consistency of the keyboard can be quantified. In order to test the quality and consistency of a keyboard, we are using a texture analyser that is programmed to measure and display the actuation force of the standard keyboard keys.
