Video switch is required to mux/multiplex several video sources, enable multiple camera to be displayed subsequently on a single monitor. This multiplexing could significantly reduce the cost and the space for the monitor. High off isolation means that the signal path from input to output will be completely disconnected, ensuring there will be no signal leakage and cross-talk between channels.? The core of this video switch/multiplexer is DG542 integrated circuit, here is the schematic diagram:
