Abstract

PURPOSE:To display the input and output state and automatic switching of two different input signals, by detecting the presence of input signals and operating switching means. CONSTITUTION:When a switch 12 is selected to terminals A,A', if an input ''1'' is applied to a terminal 1, an output is produced from a signal detecting circuit 7, and a moving contact of a replay 9 is connected to the contact (a) side. An ''input 1'' is outputted from the 1st and 2nd output terminals 6, 10 as ''output 1'' and ''output 2''. If no ''input 1'' is present and ''input 2'' is applied to a terminal 2, the moving contact of the relay 9 is positioned to the contact (b) and the ''input 2'' is outputted to the output terminal 10 as an ''output 2''. When the switch 12 is turned to terminals B, B', automatic switching is stopped. Further, these switching states are displayed at light emitting elements 14-18.
