KUJ Type, KUK Type and KUL Type are tactile membrane keyboard type from Mitsumi that appear to be targeted towards notebook computers.
Description
As with many other contemporary membrane switch types from Mitsumi, these types featured Mitsumi's "chip diode on membrane" to provide N-key rollover.
Tactile feedback and return force is provided by way of buckling rubber sleeves similar to KKQ Type and KPQ Type. The cross section diagram implies that the shaft within the keycap itself applies pressure to the membranes.
The three series offer four different sets of dimensions:
| Type | Height | Travel |
|---|---|---|
| KUJ | 7.5 mm | 1.5 mm |
| KUK | 9 mm | 2 mm |
| KUL | 10 mm | 3 mm |
| KUL | 11 mm | 3 mm |
Height is measured from the bottom of the backplate to the centre of a keycap. All three have the same tactile force.
Keyboards
None to date.
