Abstract

645,896. Gravity switches. SMITH & SONS (ENGLAND), Ltd., S. March 1, 1948; No. 6482. [Class 38(v)] [Also in Group XX] An erecting switch for a gyroscope comprises a circular or partcircular liquid container 15 secured to the inner gimbal of the gyro and provided with two arcuate contacts 19, 20 of the same radius disposed about the precessional axis 11 so as to provide a gap between them which may be bridged by a globule of mercury 18 and a third arcuate contact 21 concentrically arranged with respect to the other two but spaced therefrom and arranged to extend across the gap so as to be permanetly in contact with the mercury.
