Reed Switch Patents (Class 65/DIG12)
  • Patent number: 4769622
    Abstract: A novel reed switch element and method of fabricating the same comprises a ferrous alloy reed which is positioned in a glass envelope. The reed element is characterized by a layer of substantially pure titanium or chromium applied on that portion of the reed element which is in registration with the seal region of the glass envelope. Reed switch elements fabricated in this fashion display substantially improved glass-to-metal seal strength.

  • Patent number: 4055888
    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.
