ABSTRACT:
A mercury-wetted relay construction is disclosed in which a substantially flattened "Z" shaped armature (20) is mounted by means of a flexible hinge (19), at one side of the stem (11) to extend in an overlapping and spaced-apart relation with a contact (16) mounted on the other side of a pole-piece (12), the armature (20) thereby crossing the common longitudinal axis of the stem and pole-piece. An armature oscillation dampening bumper (23) is affixed to the other side of the stem (11) which extends parallel and in a spaced relation with the armature (20) at the contact end. Because of the operating direction of armature (20), the latter member may be abutted against the stem (11) end to reduce to a minimum the magnetic reluctance at this juncture.
