The 4-relay radio controlled switch FE3 Q2, together with series FS3 radio transmitters, enables wireless switching of electrical equipment (even without line-of-sight connection). It can be applied as a serial switch, for transmitting contact statuses or for controlling motors and blinds. The device distinguishes switching functions “ON/OFF“ (alternating ON/OFF by means of one transmitter button = 1-button control), as well as „defined ON” and „defined OFF” (both by means of separate transmitter buttons = 2-button control). The various functions are programmable.
