PROBLEM TO BE SOLVED: To provide a high frequency switch of a shunt type having a high reliability even to the use of high power high frequency signal, by reducing an occurrence probability of self actuation and latching phenomenon. SOLUTION: The high pressure signal switch has a signal line and a grounding line installed on a substrate and connecting conductors are arranged opposed to each other on it, and a displacement means for displacing the spacing between the connecting conductors and the grounding line is provided. When cutting off the signal propagating in the signal line, the signal line is grounded through the connecting conductor by bringing in proximity the connecting conductor and the signal line by the displacement means. When conducting the signal, the connecting conductor is insulated and made a stray potential, and the connecting conductor and the signal line are separated by the displacement means and the signal is conducted.
