Abstract
409,510. Press - button switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) May 8, 1933, No. 13365. Convention date, May 7, 1932. Addition to 409,075. [Class 38 (v).] In a switch of the kind described in the parent Specification an additional spring is provided for assisting the return action. A push-button f acts through a plunger d on a hollow elastic body b to compress it. When the elastic body has been partly compressed, a flange i on the plunger engages a disc k to compress a spring l until a spring g has been sufficiently strained to move a contact bridge h suddenly downwards past a spring-pressed ball which then holds it in the on position. The button f is returned by the spring g as soon as it is released. The hollow member b gradually fills with air and acts on the contact bridge through the plunger d to cause the bridge to snap to the off position assisted by the spring l acting through the disc k.
