Abstract

1. A high-sensitivity permanent-magnet latching relay with a magnet yoke (1, 2, 3) and a permanent magnet (7) secured thereto, an armature (4) mounted on the limbs (1, 2) of the magnet yoke and loaded by a spring (5), and an excitation coil (6), surrounding one (2) of the limbs of the magnet yoke (1, 2, 3), and with a thermo-alloy arranged in the magnet circuit, characterized in that, for the purpose of obtaining a constant response threshold independently of the surrounding temperature, a magnetic resistor (8) made of a thermo-alloy is arranged between the permanent magnet (7) and the magnet yoke shunt (3).
