'''Matias switches''' are [[Alps clone|clones]] of the [[Alps SKBM White]] and [[Alps SKBM Black]] switches, designed by [[Matias Corporation]]. These switches were introduced by Matias as replacements for the [[Alps SKBL/SKBM series]] upon its discontinuation by [[Forward Electronics]]; design and development took two years<ref name="Announcement" /> and was instigated upon threats from Forward of termination of production of their switches, and a lack of suitable products on the market.<ref name="DT-Matias" />

==Description==
Matias switches are based heavily on the simplified Alps design. The shell is completely transparent, allowing for [[light-emitting diode|LED]]s to be mounted directly underneath the switch. Alps-type switches with tactile and [[click leaf|click leaves]] do not have room for an integrated [[light-emitting diode|LED]], and having the switch lit from below is Matias's alternative to using linear switches with integrated LEDs for lock keys. The major reason for this is customer complaints and returns arising from misunderstanding over the linear lock keys on the [[Matias Tactile Pro]] keyboards, which are by design and necessity, not a defect. Lock keys are thus able to have the same sound and keyfeel as the other keys on the keyboard.

Unlike typical Alps clone switches, Matias switches are externally an exact replica of Alps switches including the four wing-shaped plate retention clips.

The [[ping]] ("chorus of springs") which plagued SKBL/SKBM switches is reported to be eliminated;<ref name="Announcement" /> the cause of this is given as excessively thin springs that pick up vibrations from other switches.<ref name="AnotherQuiet" />

Matias switches are used in Matias keyboards and can be ordered separately. Possibly intended for the [[Matias Tactile Pro 3|Tactile Pro 4]], they were first introduced in the [[Matias Tactile Pro 3|Tactile Pro 3]] when stocks of [[Forward SKBM White]] switches ran out, which were discontinued by Forward in early 2012.

Final assembly is done by [[Gaote]].<ref name="DT-Matias" /> The switches are shown on the Gaote website and available from their Alibaba store.

Initially, the switches were manufactured unbranded; this has been reported to be an oversight. Branding has subsequently been added, but to the front of the switch above the mounting plate, instead of the top.

==Variants==
===Click===
The ''click'' switch (part no. KS101, previously PG155B02) is a clone of the [[Alps SKBM White]] switch and is intended as a direct replacement for it.

===Quiet click===
The ''quiet click'' switch (part no. KS101Q, previously PG155B01) is a clone of the [[Alps SKBM Black]] switch, with the damped [[slider]] from the [[Alps SKCM Cream Damped]] switch. The quiet click switch is a tactile switch designed to make as little noise as possible, and the term "quiet click" is a misnomer: the switch does not click.

The [[slider]] has two rubber bumpers that cushion both the down-stroke and the up-stroke. The bumpers [[damping|dampen]] the [[clack]] noise on [[bottom out|bottoming out]], as well as the noise when a key is released, thus making keyboards with this switch quieter. Unlike cream Alps, the rubber bumpers are white instead of black.

Matias first intended to make the switch with an orange slider, but had to change the colour to white because the pigment used in test batches interfered with the plastic's properties.<ref name="Announcement"/> The slider colour has subsequently been changed to grey; the shade of grey has also changed.

===Quiet linear===
The quiet linear switch (part no. KS102Q) has a red slider with rubber bumpers that dampen the sound both on the down-stroke and up-stroke.
The helical spring is identical to that used in the Quiet Click. Unlike linear [[Alps SKCL]] switches, there is an additional leaf spring as in tactile switches but it lacks any tactile bump.

==Tactile Pro 2 switches==
[[Strong Man]] was the OEM for the [[Matias Tactile Pro 2.0]], and they claimed that the switches used were their own product. Matias referred to these switches as "Matias switches", to provide a more professional name than "Strong Man switches". The switches have since been found to be the same [[Forward SKBM Grey]] switches that were used in late-issue original Tactile Pro keyboards (de-branded Alps SKBM Grey).
