'''NMB dome with slider''' is a type of membrane [[rubber dome]] switch with [[slider]]s with a proprietary [[keycap mount]].

==Description==
These keyboards use discrete domes that are glued to the top membrane sheet. The dome colour varies between keyboards, and this characteristic has yet to be studied or explained. In most rubber dome keyboards, the domes are made from a medium opaque grey or translucent colourless material, and the use of brightly-coloured domes is unusual.

The keycap mount is proprietary; the slider snaps onto a horizontal bar inside the slider.

==Specifications==
The specifications for the NMB RT-2200W cite the switch as an "Ultra Silent Membrane Keyswitch", and the keycaps are helpfully noted as being made of "Thermoplastic" with UL flammability rating 94 HB.<ref name="AW-2200" />

The interesting specifications given for model RT-2200W are:

{| class="wikitable"
! Characteristic !! Value
|-
| Contact material
| Mylar with silver-carbon overlay
|-
| Keyswitch travel
|  0.140 ± 0.020 inch (3.56 ± 0.5 mm)
|-
| Travel to make
| 0.090 ± 0.020 inch (2.29 ± 0.5 mm)
|-
| Operating force
| Momentary Action: 2.0 oz. nominal (55 grams)
|-
| Feel
| Tactile
|-
| Life

Whether these specifications hold true for the entire series is not known.

===Digital RT10x===
The sliders are normally colourless, as seen in the 2nd image of a [[Digital RT101]], but the [[Digital RT102]] keyboard has been found with black sliders:
