ABSTRACT:
A miniature relay comprises a main body (1) having a coil (2) disposed on a core (3) riveted to a yoke (4), the yoke having a segment (4") substantially parallel to the axis of the coil (2) and receiving an armature (5) withheld by a resilient member (6), which maintains the armature transversely positioned relative to the core (3) and able to be attracted at least by a magnetic field produced by the coil (2), with the armature(5) being further provided with a flexible blade (7) on which two extreme breaker points (8) are held, the assembly being also provided with a supporting base (9), where fixed breaker points (10) are received and in which the extreme breaker points of the blade (7) operate, and a box (11) attachable to the said base (9), with the blade (7) being formed by a bifurcated plate, bordering a portion (12) for interconnection to the armature body and two elongated coplanar branches (13), whose free ends receive the breaker points (8) and, adjoining the point of bifurcation, are provided with a bend (14) whereby the entire extreme portion of branches (13) is held away from the armature body (5); while the fixed breaker points (10) are each mounted on a resilient structure (17), housed by a compartment (18) provided in a subassembly (19), fixed to a blade holder (20). Among other advantages, the relay provides a low noise level.
