MENTOR's illuminable push button caps have been designed for membrane keyboards on a circuit base (short-stroke keypads). Single switch applications of keys are also possible. By the use of the illuminable push button caps the respective switching states can now also be shown visually. Due to the 2-component construction with diffusing screen and casing a very homogeneous illumination of the area of the cap is possible with only two LEDs. The push button cap is put onto the push button afterwards. The color of the LEDs and also the tactile characteristics of the push button can therefore be determined individually by corresponding choice. Here, the push button cap remains unchanged. (The push buttons and LEDs are not part of the scope of supply.) By equipment with different-colored LEDs or RGB LEDs it is possible to signal different colors and switching status fully adapted to the requirements of the environment of the controls.
The document presents Mentor's illuminable push‑button caps (Tastkappe) and signal indicators (Leuchtfeld) designed for membrane keyboards and control panels. It explains how the caps are mounted on existing switches and how different LED colors or RGB LEDs can be used to signal various switching states.
Technical data such as housing material, diffuser disk, operating temperature, climate class and minimum order quantities for special designs are listed, together with layout suggestions and contact information for worldwide sales offices. This manual is written in German.
