Claims

[Scope of utility model registration request]

A first line made of a conductor of a predetermined length between the input and output terminals, and a second line made of a conductor of a predetermined length parallel to this first line.
a line, a wire-shaped movable contact provided at both ends of the second line, fixed contacts in contact with these movable contacts and connected to terminating resistors having a predetermined characteristic zampedance, and a case member that holds and houses a line and has an insertion hole near the fixed contact into which a connection line with a center conductor is inserted, and when the connection line is inserted into the insertion hole, the center conductor is inserted into the case member. presses the movable contact to disconnect the movable contact from the fixed contact, and 1. A termination switching type directional coupler characterized in that the perturbation contact is connected to the center conductor of the connection line.
