摘要: A keyboard has a protective foil which is a formed part to have dome-shaped vaults extending upwardly from a foil floor at respective individual keys of the keyboard. The protective foil is inverted (dome interiors open downwardly) so that the keys are respectively arranged relative to the vaults (8) and replaceable caps (9) are snapped onto the vaults and keys.

摘要: A rigid polyvinyl chloride foil with modified impact resistance and free from plasticizer especially suitable for the manufacture of audio-visual information carriers with stamped spiral grooves from which the information is played back by pressure scanning. The foil is characterized by a special combination of properties such as flow, reduction in length, toughness, surface resistance, elasticity, peak-to-valley height and surface deposit.
