The push button interface is a binary input and output device for installation in in-wall boxes (∅ 60 mm, depth: 40 mm). Each of the four channels may be used either as an input for po- tential-free switch / push button contacts or as an output for control of a light emitting diode (LED). The required scanning / control voltage is provided by the push button interface (requires no additional power supply). Up to 4 switches/push buttons with one potential-free contact each or up to two 2-fold push buttons with two potential-free contacts each may be connected to a push button interface. The connection is carried out via a cable set which is perma- nently connected to the push button interface. The connecting cables between switches/push buttons and the push button in- terface may be extended up to 10 m. It must be ensured that twisted cable pairs are used. Commands can be given to actuators via the connected switches/push buttons, e.g. for defined switching on/off, for dimming fluorescent lamps or for
