IPC: H01H36/00
Filed: 1988-03-24
Abstract: PURPOSE:To prevent incorrect operation due to induction field near an installation position by moving an oxide superconductor by Meissner effect. CONSTITUTION:A photoelectric switch 6 is actuated by utilizing the Meissner effect of a normal temperature superconductor 2 without using a contact point opened and closed by electric field. Namely, in the case a device A and a device B is apart from each other, the normal temperature superconductor 2 is pushed forward by an elastic body 3, and a light from a light emitting section 4 is obstructed and does not reach a light receiving section 5. As a result, a signal of closure is sent to a photoelectric switch 6. When the device A approaches the device B, a magnetic attachment piece 7 approaches the normal temperature superconductor 2 and they repulse each other by the Meissner effect and the normal temperature superconductor 2 retreats and the elastic body 3 is compressed. As a result, the light from the light emitting section reaches the light receiving section 5 and a signal of opening is transmitted. This prevents incorrect operation due to induction magnetic field caused by a large external current.
