ABSTRACT:
Disclosed is an improved switch particularly adapted to be used as a coaxial cable switch for cable television systems because of its superior isolation of the signal inputs. The switch comprises an electrically insulating body, first, second and third terminals located on the body in spaced relationship, a movably mounted contact, which is movable along a predetermined path to form alternative conductive paths between the first terminal and either of the second or third terminals, and a partition means between said terminals and located adjacent the path of the contact to form a barrier to radiated signals from whichever of the second and third terminals that is not in contact with the movable contact. Additionally, terminating means for the unused terminal and/or shielding means to further isolate the unused terminal from the used terminal can be provided.
