ABSTRACT:
An improved high frequency selecting switch terminal comprising two conductor pins which are coaxial. When a conductor pin from a cable is inserted into the terminal, it pushes the front end of the first conductor pin forward into the front end of the second conductor pin. At the front ends of the first and second conductor pins are first and second sliding blocks which force the pins forward. Thus, input signals are transmitted from the cable to the switch. The terminal further comprises a thick film resistor which connects the front end of the second conductor pin and a conductor ring which is disposed on the front surface of the second sliding block. When the cable is removed, the first and second sliding blocks move to the original position and the conductor ring contacts with the rim of the terminal housing. In this way, the terminal absorbs undesirable signals from the surroundings so as to prevent interference.
