Claims (1)
して接続し、前記能の回路へ到る端子と接点との間に第
１の電圧を供給する第１の電源を接続するとともに、前
記第１の電圧より絶対値の小さな電圧を有しかつ第１の
電源の電流よりも大きな電流を有する第２の電源を逆流
防止素子を介して接続した接点電圧供給回路。A terminal leading to another circuit and a reference voltage terminal are connected via a contact, and a first power supply supplying a first voltage is connected between the terminal leading to the circuit and the contact. At the same time, a contact voltage supply circuit having a second power supply having a voltage smaller in absolute value than the first voltage and a current larger than the current of the first power supply is connected via a backflow prevention element.
