PURPOSE:To reduce signal leakage between input and output terminals and the effect on external circuits, by connecting two switching elements in series at (b) contacts mutually and terminating (a) contacts with a suitable impedance. CONSTITUTION:A switching element changing over an input terminal 4 to a (b) contact 6 and an (a) contact 6' and a switching element changing over an output terminal 10 to a (b) contact 8 and an (a) contact 8', are controlled to the (a) contact or (b) contact at the same time. The contacts 6, 8 are connected with a lead 7 and the contacts 6', 8' are terminated at resistors 5, 9 respectively. |
