Abstract

1,108,513. Electromagnetic contactors. WARMEX Ltd., and A. GOLDSTEIN. 21 Dec., 1965 [2 Aug., 1965], No. 32993/65. Heading H1N. In a plunger armature relay the plunger carries a suction cup which in the armature attracted position engages a second suction cup provided with a small air inlet so that on deenergization the resetting movement is delayed for a predetermined time.
