Abstract

964,351. Electromagnetic relays. P. R. MALLORY & CO. Inc. March 23, 1961 [May 27, I960], No. 10625/61. Heading H2B. A resonant relay including a multiplicity of tuned reeds arranged when oscillated at their respective frequencies to be attracted and held by the operating electromagnet against permanent magnet bias has a rectifier in series and a capacitor in parallel with its coil so as to provide the pulsating D.C. required in the coil when an A.C. input signal is applied to the circuit. As shown, the reeds 23 are secured to a base 10 with the permanent magnet 30 and with arms 31 extending from one pole of the magnet 30 to attract the reeds 23 away from the pole 15 of the electromagnet 11. When a reed is held against the pole 15 on energization a contact 33 on the reed engages a respective fixed contact 20 on an arm 18.
