Mitsumi KSR Type|
Possible Mitsumi clone
The Commodore 64 typically used a linear Mitsumi KSR Type keyboard, with a PCB. Into the PCB is fitted a discrete latching action switch for shift lock; this switch is exceptionally smooth for a latching switch. The sliders use a cruciform mount instead of the more common square Mitsumi mount.
The keycaps are spherical double-shot; the front legends are likely to be pad printed.
The keyboard PCB model across all variants (C64, C64C and C64G) is KSR-A66YF.
Some Commodore 64 computers use an unidentified keyboard with Mitsumi-style sliders, but with an SMK J-M0404 series switch for Shift Lock. Typically, keyboards sourced from other manufacturers use whatever switches they have in their product range, but here, it looks like an attempt was made to clone the Mitsumi KSR switch mechanism. The PCB is marked "ACTION", which may indicate the manufacturer. The Mitsumi manufacture date label is also absent.
