Abstract

PURPOSE: To reduce the number of the poles of a connector, and to reduce the cost of production by providing a switching means by which a main electric circuit receives a discrimination signal through the connector and switches the connection or the operation of a circuit element so as to adapt itself for an additional electric circuit.
CONSTITUTION: When a circuit A 1 as the main electric circuit and the circuit B 2 as the additional electric circuit are connected by the connector 3, power is supplied from a circuit A 1 side, and levels determined beforehand are set in the signals S1 to Sm of the circuit B 2. The set levels are supplied to the switching means 4 of the circuit A 1 through the connector 3, and one of them is selected. The selected signal connects a partial circuit of coupling the circuit A with the circuit to output the signals I1 to Il of the circuit B and performing some processing function. Thus, the number of the poles of the connector to be used for connection can be curtailed, and the cost of production can be reduced.
