If you know a device you are going to produce will require in the course of manufacture so far unknown changes to legends of keys, for instance because of a new language version, individual changes to device functions and the like, we can make pockets for inserting cards with legends in the membrane switch (see Fig. 1).
Fig. 1
Legend pockets away from the keys can be created in all types of membrane switches. Legend pockets for legends in a location of keys cannot be done in polydome membrane switches.
We recommend strips of paper or a film approx. 0.1 mm thick for legend cards. The legends can be inserted from the perimeter of the membrane switch, or from the back (front), looking at the graphic overlay.
