Abstract
A reed switch having contact electrodes extending within a sealed envelope to overlap and form a magnetically actuable contact gap of the switch. Each contact electrode has flattened bladed portions which taper from their overlapping forward extremities to form blades of varying thickness, the thickest part of the blades being at the overlap between them.
Claims2
A reed switch comprising a hermetically sealed enclosure, and a pair of electrodes extending within the enclosure, each electrode having mutually orthogonal dimensions of length, width and thickness and being flattened over a part of its length to provide respective flexible cantilevered electrode blade portions having free ends, the free ends having an overlap region within said enclosure extending in the length and width dimensions to form a magnetically actuable contact of said switch, characterised in that the blade portion of each electrode is tapered in the thickness dimension so that the thickness of the blade portion increases uniformly towards the free end.
