The Ergo Clear mod is a Cherry MX switch that has been modified with a slider from a clear switch and a lighter spring.



In the original recipe, the spring is from a Cherry MX Black switch. Ergo clear later became associated with the use of springs from brown, red or blue switches, and the name has stuck.

They feel somewhat like the Brown switch, but with a bigger, longer tactile bump. Some users have reported "sticking", where the slider fails to return past the tactile point. Sticking can be reduced with lubrication or by choosing a somewhat stronger spring.

Panda Clear

The Panda Clear switch is a Cherry MX switch with a slider from a Clear switch and a spring from a Black switch.

It was named "Panda Clear" in 2011 after the Geekhack user panda-R who modified switches this way, and because of the two colours white and black resemble a Giant Panda's fur.

Custom Springs

The denomination "Ergo Clear" is also being used for switches with third party (Korean) springs.

Some users have also used custom Korean springs at 55–60 cN with Clear sliders to produce a switch between the original Ergo Clear and Panda Clear in feel, and which avoids "stickiness".

Note that these springs are often measured by their bottom-out weight, not weight at actuation when used in a linear-feel slider.


The switches are usually made by enthusiasts by combining parts from other switches.

On request, Cherry has stated that they will actually produce Ergo Clears in a slider-colour of choice, with a minimum order of at least 750,000 switches. Keyboard enthusiasts have yet to agree if such switches should be called Beiges, Pinks or Violets.[Citation needed]
