Differences between the model numbering rules and on-board features of the Topre REALFORCE keyboard

The Topre REALFORCE keyboards look the same, but in fact there are differences between models. In this issue, we summarize the differences between the model numbers and functions of the REALFORCE keyboards.

Model numbering rules for Topre/REALFORCE

The model number of the Topre REALFORCE keyboard is composed of the following three elements.

  1. generation
  2. size
  3. function

The generation starts with R. The latest model is "R3" and the one before is "R2".

Regarding size, models without any description are full-size, and "TKL" is a tenkeyless model, but from the R3 generation, TKL is not included in the model number.

As for the last feature, there are two

  1. A = APC (actuation point changer)
  2. S = Silent (silent)

However, in R3, APC has become the standard, so the "A" is no longer indicated.

Let's use the rules we have seen so far to determine the model from the model number.

For example, "R2TLSA" is the following model.

  1. R2 generation
  2. ten-key-less
  3. quiet and APC model

Differences in the functionality of the Topre/REALFORCE keyboard

Next, let's take a look at the differences in the features of the Topre REALFORCE keyboards.

The Topre REALFORCE keyboard models are divided into five categories. 1.

  1. supported layout (Windows / Mac)
  2. size (full size / tenkeyless) Built-in functions (silent, APC) 1. Key load (30g, 45g, variable load)
  3. color

The two most important differences in terms of keyboard functions are "built-in functions" and "key load.

搭載機能の違い

First of all, there is a big difference in whether or not the model is equipped with APC (Actuation Point Changer), a technology unique to Topre.

APC (Actuation Point Changer) is a function that allows you to change where the keyswitches respond. All R3 generation models are equipped with this function as standard, while R2 generation models are equipped only with "A" in the model number.

As for quietness, all REALFORCE keyboards are equipped with "Topre switches" that use a capacitive non-contact system, so they are quieter than mechanical keyboards, but are designed for quieter operation.

Key load

An interesting point about the Toplex REALFORCE keyboards is that the key load differs from model to model.

There are basically three types

  1. 30g
  2. 45g
  3. variable load

The 30g model is lighter to type on, and the 45g has some weight, but it is still a standard weight, since the standard key load for mechanical keyboards is about 50g.

Variable load is a model with different key load set for each key. The name of this model may lead you to think that it is a model that allows you to change the load, but it does not have such a function.

In the variable-load model, heavier switches are placed on areas where strong force can be applied, such as the index and middle fingers, and weaker switches are placed on areas where typing is done with the little finger.


We have looked at the model numbering rules for the Topre REALFORCE keyboards and the differences in functionality between the broad models.

At first glance, Topre/REALFORCE keyboards have a similar design, but each model has minor differences that lead to the feeling of typing and ease of use, so it is important to try various models and choose the one that suits you best.
