Abstract

926,353. Press-button retractive switches. KOOPERATIVA FORBUNDET. Dec. 8, 1959 [Dec. 8, 1958], No. 41774/59. Class 38 (5). [Also in Group XVI] A push-button 3 loosely carrying a bridging contact 9 is held in its upper, off, position by an annular magnet 6, the contact being of magnetic material. Upward movement of the contact is damped by a sheet of soft elastic material 9a. Several such switches may be arranged in a common casing 1, 2 of a computing machine.
