SK-6 Rubber Switch Sheet

Difference Between Natural and Sharp Contacts -
- Height -

With rubber switch 12 PW218-224 for SK-6 keyboard,
natural-key and sharp-key contacts are made to different
dimensions. See the figures below and note the height of
contacts.

When replacing contacts, attach the sheet in place, i.e.
match characters with keys. Do not cut the sheet at a
point other than V-cut with a groove.

NOTE

Replacement SK-G keyboard and replacement contact
PCB are equipped with a complate set of rubber sheets.
Sheets are also available as separate replacement.
