ABSTRACT:
A high frequency switch to be mounted on a board, which includes an insulating housing to be mounted on a board of a high frequency apparatus on which ground and signal conductors are disposed; a pair of parallel ground conductive plates disposed on opposite sides of the insulating housing in a direction perpendicular to the board such that when the insulating housing is mounted on the board, the ground plates are connected to the ground conductors on the board; an non-ground conductive plate disposed in the insulating housing between and at right angles with the parallel ground conductive plates such that when the insulating housing is mounted on the board, the non-ground conductive plate is connected to the signal conductor, the non-ground conductive plate including: a switching spring to be connected to one of the signal conductors on an input side, and a connection plate to be connected to one of the signal conductors on an output side; a free end of the switching spring being pressed against a free end of the connection plate by a spring force in a direction perpendicular to the board but, when a probe is inserted in a direction perpendicular to the board to depress the switching spring, the free end of the switching spring being separated from the free end of the connection plate so that incoming signals are transmitted to the probe from the one of the signal conductors on the input side.
