Abstract

419,031. Interrupters. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place Des Etats-Unis, Montrouge, Seine, France. April 11, 1934, No. 10965. Convention date, April 12, 1933. [Class 38 (v).] An interrupter which is not influenced by vibration, comprises a contact arm 1 pivoted on an axle 2 passing through its centre of gravity and engaged by a ratchet wheel 5 to make and break contact with a fixed contact 4. The contact arm is provided with a return spring (not shown) which is coiled round the spindle 2 to which one end is attached, the other end being attached to the contact arm.
