ABSTRACT:
A high frequency relay for switching a high frequency signal includes stationary contacts and terminals formed on a substrate in a planar configuration. An upper and a lower ground layer are respectively formed on the upper and lower surfaces of the substrate in the vicinity of the stationary contacts and terminals. A movable contact spring is so configured as to be connected to ground via the ground layers when it opens the contacts. With this configuration, the relay is capable of reducing the leakage of signals and thereby enhancing isolation characteristic.
