STANDARD AND OPTIONAL PROTECTION
Standard protection which is applied to any membrane keyboard:

• graphite layer as a protection of silver conductive connections on contact surfaces of a connection tail and on contact surfaces of tactile elements,
• holding foil which creates a security chamber and prevents movements of tactile elements within the keyboard,
• isolation lacquer which protects tactile elements on a connective tail prevents unwanted electric contact within the device,
• two-sided protection of clear windows (LCD windows) with protective foil;

Optional protection which can be inserted on the basis of client's special requests:

• optional foil protection of conductive connections on the connective tail which is necessary in cases of demanding environments and in cases of pasting a keyboard on metal carriers,
• EMV protection realized through an optional conductive layer (silver or graphite layer) which can be contacted on a connective tail of a keyboard or with a separate connective tail;

CONNECTION TAIL
The membrane keyboard is usually equipped with a connection tail, whose length can be adjusted to device demands. The connection with electronics inside the application can be created through a broad selection of suitable connectors. In the case of 2,54 mm pitch the connectors can be crimped on the connection tail. In the case of smaller pitches the connection tail of the keyboard is prepared for the use of FFC-FPC connectors which are parts of electronics and are not delivered together with the keyboard.
