Abstract: A latching electromechanical RF switch is formed with an RF switch cavity having at least one inlet port and at least one outlet ports having switch contacts. A leaf contact member moveable between a first contact position connecting the switch contacts and a second position spaced from the switch contacts. A solenoid mounted in the cavity. A housing is formed with a hollow passage. An intermediate permanent magnet provided within the housing. A connecting member assembly is moveable within the hollow passage. The contact leaf member is connected to one end with a permanent magnet provided at another end of the connecting member. The intermediate magnet attracts and retains the permanent magnet and the contact leaf member in the first contact position. Upon reaching the first contact position electric current supply to the solenoid is terminated.
