In order to establish the defined distances between the contact points on the decorative film and the switch film itself, Lohmann offers touch-sensitive keyboard manufacturers a wide variety of self-adhesive spacer films. They ensure a hermetically sealed system that offers long-term resistance to both mechanical and environmental loads.

Touch-sensitive keyboards with snap domes give users tactile feedback using individual settings when data is entered. In addition to spacer films, backing films with adhesive on just one side are also used in these situations. These are used to fix the snap domes in place.

Many touch-sensitive keyboards now offer visual LED-based feedback as standard. A particular factor here is that customer-specific laminates formed by doubling up standard adhesive tapes are increasingly in demand. They serve as additional spaceholders.

Short-stroke keyboards are renowned for their robustness and are a particular favourite in industrial applications. In these applications, a decorative film bonding solution is sought that is resistant to all exterior influences. A solution such as adhesive bonds from Lohmann.
