Abstract

A marking element for marking the function of a control element of an electric or electronic device with numbers or pictorial symbols. The marking element is composed of a first section composed of a first film having a luminescent layer to be applied to a control area of the control element, and a number or pictorial symbol is provided on the first section.

Claims

1. A marking element for marking the function of a control element of an electric or electronic device with numbers or pictorial symbols, wherein said marking element comprises a first section composed of a first film having a luminescent layer to be applied to a control area of the control element, and a number or pictorial symbol is provided on said first section.

2. The marking element according to claim 1, wherein, for providing the number or pictorial symbol, said element further comprises a second section composed of a clear second film carrying the number or pictorial symbol, said second section being applied on said first section.

3. The marking element according to claim 2, wherein at least one of said first and second sections is a self-adhesive film with a removable protective backing.

4. The marking element according to claim 2, wherein said second section is a self-adhesive film with a removable protective backing disposed on a reverse side of said film of said second section, and the number or pictorial symbol is disposed on the reverse side of said film of said second section.

5. The marking element according to claim 4, wherein the number or pictorial symbol is printed backwards on the reverse side.

6. The marking element according to claim 1, wherein said film is a self-adhesive film with a removable protective backing, said film has an upper side carrying said luminescent layer and an underside that is opposite to said upper side and on which said protective backing is disposed.

7. An electronic or electric device comprising:

a control element; and

a marking element for marking the function of the device with a number or pictorial symbol, wherein said marking element comprises a first section composed of a first film having a luminescent layer applied to a control area of said control element, and a number or pictorial symbol is provided on said first section.

8. The device according to claim 7, wherein, for providing the number or pictorial symbol, said marking element further comprises a second section composed of a clear second film carrying the number or pictorial symbol, said second section being applied on said first section.

9. The device according to claim 8, wherein at least one of said first and second sections is a self-adhesive film with a removable protective backing.

10. The device according to claim 8, wherein said second section is a self-adhesive film with a removable protective backing disposed on a reverse side of said film of said second section, and the number or pictorial symbol is disposed on the reverse side of said film of said second section.
