Backlit Keypads

The back-lit Profiline keypad is constructed in a similar way to the standard Profiline keypad.

One main difference in the construction of the back-lit Profiline keypad is the base membrane which is designed on the basis of an FR4 PCB. An LED is fitted in the middle of the key field on the back of this PCB.

• The key area is clear lacquered, max. ø 10.0 mm
• Key height: approx. 12 mm, tolerance +/- 0.2 mm
• Installation height of the keypad: approx. 2.8 mm, tolerance +/- 10%
• Actuation force: approx. 5N

In addition to the already available Profiline back-lit membrane keypads we now offer an advanced version!

The main difference between the new and the old Profiline back-lit version is the combination of the switch- and the light layer – these layers have been integrated on seperate layers.

With the help of special LEDs and a specific processing of the inlays a better lighting can be guarateed – of course, a durable use is possible.

The membrane consists of standard surface-material – for outdoor use we do also offer this membrane keypad made from UV-stabilised polyester.
