Editing Mitsumi standard mechanical (section)

==Evolution==
Type 1 switches all appear to have a blue switchplate. Type 2 switches are found with both blue and white switchplates. The Mitsumi-mount type 2 switches found in the Amiga 1000 have been documented as having blue switchplates<ref>geekhack — [https://geekhack.org/index.php?topic=19761.msg389989#msg389989 Amiga 2000 Cherry Keyboard]</ref>, while the same switch as shown below uses white switchplates of a design not seen elsewhere.

It would appear that blue switchplate were still in use at the start of the 1990s, but the point at which the colour changed to white isn't certain. Pictures from rzwv and MouseFan of the [[Apple Extended Keyboard II]] suggest that the change occurred around 1991; rzwv's 1993 Apple IIe keyboard with type 1 switches still has blue switchplates, but these switches may be old stock. The anomalous switchplate design below is found in switches being sold off via AliExpress, suggesting that the switches may be more recent, and the switchplate redesign may have occurred towards the end of the lifetime of the series. Presently there is not enough data to be certain of this.
