Abstract

1,089,075. Magnetic switches. A. SLANDER. July 12, 1966 [April 13, 1965], No. 15610/65. Heading H2B. [Also in Division G4] A magnetic contact device carried by a window frame is actuated by a permanent magnet carried by a blind. For use with a burglar alarm, the blind is left down so that any movement of the blind moves the magnet from the contact device which therefore completes an alarm circuit. The contact device is preferably aa sealed magnetic reed device.
