With the radio controlled switch FE3 SE, electrical equipment (lamps, dimmers, door openers, etc.) can be controlled using Schalk handheld or flush-mounting radio transmitters in pushbutton or switching mode.
The FE3 SE has a potential-free change-over contact. Due to its low height of 18.5mm, it fits behind almost every flush-mounting insert (e.g. switch or outlet sockets).
The 3 functions (toggle, on, off) can be assigned to any button of the transmitter.
The function "toggle" (alternating on/off) is used for individual control. Using the functions "on" or "off", several radio controlled switches can be controlled simultaneously (group control). The functionality of the input B1 (e.g. for wire-connected pushbutton) is also freely configurable.
