The particularly narrow switching actuator, with a width of only 1 TE, can be easily installed on a DIN rail to control a channel from the distribution cabinet. This makes the device ideal for replacing impulse switches. Control is done directly via standard 230 V push buttons, wirelessly via Homematic IP buttons or remote controls, and even anytime through the smartphone app. The switching actuator not only allows for the convenient switching on and off of a connected light via an independent channel but also serves as a replacement for a conventional impulse switch. Installation on standard DIN rails is made particularly easy with spring-loaded terminals. Even without programming, the function and wiring can be checked directly on the device during installation thanks to the illuminated display and device buttons. The connected light can be flexibly controlled via wireless buttons or remote controls, as well as anytime through the Homematic IP app (e.g., using time profiles). Alternatively, manual operation via conventional wired buttons is also possible. It is suitable for renovations (e.g., attic) as well as for retrofitting. It can be easily installed in the distribution cabinet and takes up little space due to its compact housing. No intervention in the room-level installation is necessary. Existing switches and buttons can simply continue to be used.
