Abstract: Reed switches, contact sections of the reed of which bear with a predetermined positive force against inside surfaces of an elongated envelope, are made by forming combs, each including a header web and, integral with the web and projecting therefrom, a plurality of reed elements. The reed elements are parallel with one another and spaced from one another along the web. A plurality of elongated glass envelopes are mounted in a fixture, parallel with one another and spaced the same centerline-to-centerline distance as the reed elements. The reed elements of a first comb are inserted into one end of the envelopes and the reed elements of a second comb into the other end of the envelopes until the inner ends of the opposite reeds are in the desired positions lengthwise with respect to one another.

Abstract: A reed switch is made by forming an envelope tube, non-circular in cross-section, with a known internal heightwise dimension, forming a reed element with two end-bearing portions at least one of which is part of a contact section of the reed element and an intermediate sealing-bearing section between and entirely out of a plane defined by the end-bearing portions of the reed, the distance between the plane and a bearing surface of the sealing-bearing section being greater than the internal heightwise dimension of the envelope tube; inserting the reed element into an open end of the envelope tube sufficiently far to cause both of the end-bearing portions and the bearing surface of the sealing-bearing section to bear against the inside wall of the envelope tube, the end-bearing portion of the contact section of the reed element bearing with a force greater than the force ultimately to be exerted by that portion in the finished switch; sealing at least a part of the sealing section in the envelope tube to seal s
