PURPOSE:To provide the brancher/distributor for two-wire type video interphone for enabling the terminating processing of a branch terminal not to be used with one action and separately being used as a one-brancher, two-brancher and distributor easily corresponding to needs. CONSTITUTION:A dummy terminator 10 is connected through a contact between the branch terminals of a branch 2 not to be used, and a dummy resistor switch A for closing this contact is provided on the surface of the brancher. By selectively setting the ON/OFF of the dummy resistor switch A, the contact can be opened/closed and the two-brancher can be separately used also as the one- brancher. |
