This additional control module, 18 mm wide, can be attached to the standard impulse switch and has a galvanically isolated contact level. The devices are mechanically connected. Two different control voltage potentials
(e.g. AC local, DC central) can be used between the local and central command point. The
E294 central control module is used professionally with control voltage circuits of various designs. This attachable additional device can be used to implement clean, higher-level and central commands (all off / all on). For such a solution, a central on-off control module must be attached to each impulse switch that is integrated into the central on/off control. The central commands always have priority and reliably switch the mechanically connected coil of the standard impulse switch on or off. This occurs regardless of the previous switching position of the individual impulse switches.
