Abstract

1,263,076. Inertia switches. C. B. ASSOCIATES Ltd. 15 April, 1969 [19 April, 1968], No. 18722/68. Heading H1N. An inertia-actuated burglar-alarm switch comprises a conductive sphere 2 supported on a seat comprising three pins or legs 3, two of which are in an electric circuit which is momentarily broken when the sphere vibrates. A further fixed contact sleeve 6 may be provided to complete a circuit when engaged by the sphere 2. The sleeve 6 or the insulating support 5 for the contact pins 3 may be slidably adjustable in an insulating housing 1. In modifications the housing 1 may be conductive for engagement by the sphere or a wire ring contact may be supported above the sphere. The sphere may be of magnetic or non-magnetic material and the pins may be gold plated.
