Abstract

PURPOSE:To omit attachment of a short circuit plug when a signal line connector is separated by adding an exclusive OR circuit to a controller and setting a signal line between the input terminal of said OR circuit and the input/output terminal of a constantly closed switch means. CONSTITUTION:A current flows to a common earth terminal 11 from a power supply 7 via a resistance 14, a signal line 16, a constantly closed switch means 5 and an earth line 10 in such a state where a controller 2 is normally connected to a remote controller 1 and the switch 5 is not operated. At the same time, a current flows to a resistance 15 and the voltage of the power supply 7 drops with input terminals 13a and 13b of an exclusive OR circuit 13 set at low levels. The output 13c of the circuit 13 is also set at a low level. In case the controller 1 is separated from a connector 4, both terminals 13a and 13b are set at high levels with the output 13c set at a low level respectively. In such a constitution, it is not required to attach a short circuit plug when a signal connector is separated.
