Abstract

976,743. Magnetic switches. M.A. VERMOHLEN. Jan. 18, 1961 [Jan. 19, 1960], No. 29143/64. Divided out of 973,080. Heading H2B. A float operated driving magnet (not shown) movable in a non-magnetic tube actuates a pivoted driven magnet 66, 67, between two end positions, the pole 67 co-operating with a pivoted contact-carrying armature 72 having a central aperture 75, to move it with a snap action. The magnet 66, 67 is pivoted at its centre of gravity and its movement is limited by stops 70, 71. The armature 72 is also balanced and carries contact 76, 77 which cooperate with fixed contacts 75, 79.
