Abstract
PURPOSE:To obtain one or both inputs signal as the output, by making automatic switching of two different input signals, through the control of a switching means, by detecting the presence of input signals at the 1st and 2nd terminals. CONSTITUTION:When it is desired to switch the signals of ''input 1'' and ''input 2'' automatically, the moving terminal of a switch 11 is connected to a terminal (a). When an ''input 1'' is applied to a terminal 1, a transistor 4 conducts, the relay contact is selected to the (a) side and the signal of ''input 1'' is outputted from output terminals 6,9. Further, when the ''input 1'' is absent and the''input 2'' is applied to a terminal 2, the relay contact is switched to the (b) side and the signal of the ''input 2'' is outputted to the output terminal 6. On the other hand, when the moving terminal of the switch 11 is switched to the terminal (b) side, the signal of the ''input 2'' is outputted to the output terminal 6, independently of the presence of the signal of the ''input 1''.
