Vibration switch having threaded terminals and plural roller contacts
First Claim
1. A vibration switch comprising, a housing, a side-by-side pair of substantially parallel, horizontally-disposed, elongate, electrically-conductive terminals supported within the housing, the terminals being of a configuration such as to present, upwardly, a plurality of discrete spaced-apart points and supporting from below a pair of loose, cylindrical, aligned, electrically-conductive bodies which partly occupy a space within the housing above the terminals, the terminals being spaced-apart by a distance such that the bodies cannot drop through and being respectively spaced away from the nearest adjacent part of the housing by a distance such that the bodies, if shaken out of contact with the terminals, cannot fall below the terminals but will fall back to be supported by the terminals.

Abstract
Two side-by-side elongate terminals support, from below, one or a pair of electrically-conducting bodies which contact the terminals and thus provide electrical continuity between the terminals so that vibration will cause the body or bodies to lift from one or both of the terminals and break the continuity.
