The 2-button module from Telecom Behnke is a component for telecommunications systems, specifically designed for integration into electronic devices without flat ribbon cables. It serves as an operating element with two illuminated call buttons, intended for selecting telephone lines or internal connections in industrial or commercial environments. The module is made of aluminium, ensuring high mechanical stability and resistance to wear. The buttons are surrounded by a coloured ring, enabling visual differentiation of functions. The ring colour can be selected from red, blue, green, yellow, or orange, and must be specified at the time of order.

Applications
This module is intended for use in telecommunications systems, particularly in systems that do not use flat ribbon cables for connecting operating elements. It is suitable for installations in offices, workshops, production environments, or other technical facilities where a robust and clearly identifiable operating interface is required. The use in electronic devices without flat ribbon cables is explicitly supported.

Functions and Equipment in Detail
The two call buttons are illuminated, ensuring good visibility even under low ambient lighting. The illumination serves to indicate the operating status or readiness for selection. The buttons are IP-rimmed, providing mechanical protection and shielding them from mechanical wear. The coloured ring optics support quick identification of button functions, especially in complex control panels with multiple modules.

Technology Explained Simply
The module consists of an aluminium housing, which provides both mechanical stability and heat dissipation. The buttons are equipped with illumination, activated via the electronic control of the device. The coloured ring illumination is not designed as an additional light source, but serves optical identification. The IP-rimming of the buttons protects against mechanical wear and provides a defined operating surface. Compatibility with devices without flat ribbon cables means the module connects to the electronic system via alternative connection techniques (e.g. plug connectors or printed circuit board connections).

Compatibility and Accessories
The module is specifically designed for electronics that do not use flat ribbon cables. No additional accessories or adapters are required to integrate the module into compatible systems. The connection is made via the device's designated electronic interfaces.

Mounting and Installation
Installation requires no additional tools or components, as the module is directly mounted into the device front. The electrical connection is made via the integrated terminals, designed for the respective electronics.

Advantages in Operation
The aluminium construction ensures long service life and high load capacity. The illuminated buttons improve operability in poorly lit environments. The coloured ring optics enable quick and error-free assignment of button functions. The IP-rimming protects the buttons from mechanical wear and ensures a uniform operating surface. Compatibility with devices without flat ribbon cables expands application possibilities in various electronic systems.
