The radio receiver switch FE3 SE has a potential-free changeover contact. Thanks to its low height of 18.5mm, 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, 12V UC - 1 changeover contact 10A
