Abstract

1434934 Magnetic switches F B ISAACS and R ANDERSON 9 July 1973 [14 July 1972 27 July 1972] 32946/72 and 35138/72 Heading H1N A retractive magnetic switch which may be responsive to the relative movement of two components, such as a door and door frame, is mounted on one of the components in a position so that its push-button 12 may be pushed, by the other component, into its housing 1 to move a permanent magnet 8 against the bias of a spring 9 to influence a reed contact unit 6 on the other side of a wall 7 of the housing which has two parallel elongate compartments for the contact unit and the permanent magnet actuator.
