Abstract

The invention relates to automation, radio, electrical and computer technology and can be used in automatic control systems, measurement control and communications. The purpose of the invention is to increase the vibration resistance. Inside the sealed balloon, two light guides 2 are mounted in a cantilever and opposite each other. In the gap between the ends of the light guides, there is a smaller portion of the L-shaped shutter 3, which is reinforced in a cantilever at the cylinder's face. The curtain end of the shutter serves as the output of an electrical circuit. A ferromagnetic plate 4 is fastened at the opposite end of the baplon, the protruding end of which serves as the second terminal for the electric circuit. A ferromagnetic plate 5 is welded to the L-shaped P1orke; its free end is located above plate 4 with a gap of 100–200 µm with overlapping. 1 il. (L

Claims (1)

Claim A magnetically controlled switching element comprising a sealed container, two optical fibers with polished ends mounted cantileverly and counter to each other inside the container at its opposite ends, and a L-shaped ferromagnetic shutter mounted cantilever in one of the ends of the sealed container so that its smaller section located above the gap between the ends of the optical fibers, different! the fact that, in order to increase vibration resistance, two ferromagnetic plates are installed in it, one of which is rigidly fixed to a larger portion of the L-shaped ferromagnetic curtain, and the other is cantilevered in the opposite end of the sealed one. the cylinder, while the free ends of the ferromagnetic plates are installed with the possibility of contact.
