With the FE3 SE radio receiver switch, electrical equipment (lamps, touch dimmers, door openers, etc.) can be controlled wirelessly in switch or touch mode using Schalk radio handheld or flush-mounted transmitters. The FE3 SE radio receiver switch has a potential-free changeover contact. Thanks to its low height of 18.5 mm, it fits behind almost any flush-mounted switch box insert. The 3 functions (toggle, on, off) can be assigned to any transmitter button. The 'toggle' function (alternating on-off) is used for individual control. Several receivers can also be switched together using the 'on' and 'off' functions (group control). The function for input B1 (wirable local input) is also freely selectable., Compatible products: radio transmitter FS3 series, repeater FV2 R., Dimensions: 43x43x18.5mm, 230V AC - 1 changeover contact 10A
