ABSTRACT:
A coaxial jack with an internal switch mechanism includes a cylindrical shell having an axial front opening, and an elongate center conductor supported coaxially inside the shell. A back end of an elongate resilient switch contact is fixed by a switch contact support at a back portion of the shell on one side of the shell axis. The switch contact extends inside the shell toward the front opening at a certain inclination and has a free end located on a side of the shell axis opposite the one side. The switch contact is configured and positioned to make an electrical connection with the center conductor in the absence of a mating plug. An elongate actuator is supported on the inner periphery of the shell and has an engaging part that protrudes into a defined plug travel path inside the shell. The engaging part is configured to cause the free end of the switch contact to deflect by an amount sufficient to break the electrical connection between the contact and the center conductor when a mating plug travels into the shell and displaces the engaging part of the actuator.
