Abstract:
1. An electromagnetic relay, comprising: a plurality of fixed terminals, each having fixed contacts; a movable block holding a movable contact piece having a movable contact point contacting with and departing from the fixed contacts; and an electromagnetic block for driving the movable block, wherein the fixed contacts are opened or closed by driving the movable block by exciting or not exciting the electromagnet block to transmit or shield a high frequency signal, each fixed terminal is supported by a side of a base composed of a dielectric material and having an internal space and upper and lower planes and four sides, the fixed contact of each fixed terminal is exposed to the internal space, a surface of the fixed terminal is disposed parallel to a bottom of the base, while the movable block is disposed in the internal space of the base, signal lines are formed of the fixed terminals and the movable contact piece, and shielding portions to be grounded are disposed at either an upper part or a lower part of the internal space corresponding to the signal lines, the shielding portions having a plurality of terminals extended from at least two opposite sides of an edge of the shielding portions and lying in a horizontal position with respect to the relay.
