Electric relay having multiple operational thresholds |
摘要 |
Electric relay comprising flexible-blade switches having multiple operational thresholds. In this relay, the most sensitive switches are within the coil whereas the least sensitive switches are located outside the coil, the magnetic circuit being directed toward the outside switches by the use of magnetic flux detectors. Moreover, the operational thresholds of the switches are adjustable by the use of magnetic shunts disposed in the coil and in the flux detectors, one of the shunts being constituted by a material chosen for its Curie point.
