信制御回路。 On a telephone circuit consisting of two terminals, the stationary contact side of a telephone switch is connected to one terminal of the telephone circuit, and one end of the communication circuit network and one end of the receiving side of the dial control terminal are connected to the make contact side of the telephone circuit. The other end of the receiving side of the dialing control terminal is connected to one end of the dialing circuit, and the other end of the dialing circuit is connected to the other end of the telephone circuit network and the terminal of the other end of the telephone circuit, and conductive. By attaching and detaching a U-shaped dialing terminal to the receiving side of the dialing terminal, direct current from a telephone exchange is controlled to the dialing circuit to set the operation or non-operation of the dialing circuit, thereby controlling dialing. A dial control circuit for a telephone set, characterized in that:
