2in/1out switch controlled by 0/12 V applied to DC socket of the switch, usually from a satellite receiver. It is possible to connect 2 satellite dishes to the inputs and a satellite receiver to the output of the unit, or to use a reversible connection, when the signal is distributed from one coaxial cable into 2 satellite receivers (e.g. analog and digital ones), and the required receiver is switched by means of 0/12 V on the DC socket. The unit is going through for 22 kHz and DiSEqC signals.
